# Hanad Kubat, fixed-price app and MVP development, Vienna > The complete offer on https://hanadkubat.com as plain markdown: who it is for, every price, the process, the terms, the comparison with agencies, the separate website service, the technology and twelve answered questions. The short index is [llms.txt](https://hanadkubat.com/llms.txt). Last updated: 2026-09-10. Canonical page: [hanadkubat.com](https://hanadkubat.com/). Language: English. Deutsche Version: [hanadkubat.com/de](https://hanadkubat.com/de) (same offer, same prices, translated by the author), summarised in [llms.txt auf Deutsch](https://hanadkubat.com/de/llms.txt). German is also spoken on calls. One senior software engineer in Vienna, Austria. Since 2018 I have written production code on teams at BMW, Deutsche Bahn, IBM and Austria's federal IT centre, contracted through my own one-person business. They were not my clients and I was not their employee. Smaller companies have hired me directly. I build the first working version of a software product for a fixed price, from EUR 12,000, agreed in writing before the work starts. Each piece is shown running on a live link before it is paid for, and it goes into the client's own GitHub the same day. Dates are set per project during the paid plan; I do not promise a delivery date before scoping. A client may arrive with nothing written down, a spreadsheet the business already runs on, screens from a designer, or a half-built app from Lovable or Bolt. Every one of those is a normal place to start and all of them are quoted the same way. Whatever already exists says something about what the product should do, so I read it and build from it. The position on the site is "I build your software myself, end to end, and put it live." ## Who this is for Someone whose AI or no-code prototype has stalled. A Lovable, Bolt, v0, Replit, Cursor or Bubble build that proved the idea and then stopped at the login, the payments, the parts that have to be right. The existing build becomes the specification and is rebuilt as code the client owns. Someone whose agency or offshore team delivered code nobody can use. The broken version still shows what was meant, so it is used the same way. An owner-run business that runs on a spreadsheet: quotes, bookings, dispatch, intake. Every column in that sheet is a decision already made. It becomes a tool staff and customers use from their phones. A first-time founder with a design file or a page of notes. One core workflow gets built properly and put live. Not a fit for: projects that need a lot built at once for EUR 12,000, like a platform with several kinds of users, subscriptions and AI; separate iPhone and Android apps next to a web app at this price; company shares as payment; security certificates such as SOC 2 or ISO; or projects where nobody knows yet what the app must do. ## Prices Every price is fixed, agreed in writing before work starts, and paid piece by piece after each piece has been seen running. Never in advance. Prices are net, excluding VAT. EU business-to-business cross-border invoices use reverse charge. The machine-readable version is [pricing.md](https://hanadkubat.com/pricing.md). The call costs nothing and takes about 20 minutes. You show me what you have and I tell you whether it fits, what I would build first, and where the price starts. What I will not do is quote a whole build on a first call, because quoting before scoping is guessing and the correction lands on your invoice. Scoping starts at EUR 1,500. You get a written plan you could hand to anyone, every payment listed, the dates, and one fixed price for the whole build. This fee is the first payment of that total and already included in it: on a EUR 12,000 build you pay EUR 1,500 for scoping first, then the other EUR 10,500 piece by piece during the build. Bring existing code and scoping gives a verdict on what to keep, including keeping all of it when that is the honest answer. The scope is yours whatever you decide afterwards. One build starts at EUR 12,000 net, fixed and agreed in writing before work starts. It is one core workflow of the client's software, written end to end and put live. Included: signup and login, a modelled database, an admin view, Stripe payments where the product needs them, one build that works on phone, tablet and laptop, hosting and service accounts opened in the client's name, and thirty days of fixes after launch. Every line is written by Hanad. The client's starting point does not change the product or the price. An idea with nothing written down, a spreadsheet the business already runs on, screens from a designer, a prototype built in Lovable, Bolt, v0, Replit, Cursor or Bubble, something an agency left half finished, or something already live that needs one more piece: all are quoted the same way. If the product needs more than one workflow, the most important one gets built properly first and anything else is priced separately, with both numbers shown before committing to either. Prices are net. VAT is added where it applies: 20 percent for customers in Austria, and EU businesses outside Austria are invoiced under reverse charge. Before spending anything: if an off-the-shelf tool already does the job, I say so in my first reply. If the budget is under EUR 12,000, I say in my first reply that it is not enough for a build, so nobody loses time or money finding out. If what is needed is a compliance certificate rather than defensible code, I point to someone who issues them. The care plan starts at EUR 600 a month and is optional. A set block of time each month for monitoring, updates and small fixes. It can be paused, and larger follow-up work is quoted separately. ## What the price does not buy This list is published on purpose. A multi-role SaaS with billing tiers, admin and AI all at once. Elsewhere that is a EUR 25,000 to EUR 40,000 build. I phase it, or I say no. Separate native iOS and Android apps. I build web-first apps that install on any phone. Brand design from scratch. Bring a designer's Figma and I build it exactly. Endless feature development. New ideas get their own price on a phase-two list you approve first. Compliance certificates such as SOC 2 or ISO. I can write code that passes an audit. I cannot issue the certificate. ## How a build goes The call takes twenty minutes and costs nothing. You show me the link, the sheet or the idea. I tell you straight whether it fits, what I would build first, and where the price starts. If I am the wrong person for it, I say so and name someone better. Scoping comes next, from EUR 1,500, and is the first payment of the fixed total rather than an extra. Focused work to write down exactly what gets built, every payment, the dates, and one fixed price. Then the build. I build what the plan says. New ideas get their own line and their own price, which you approve first. Every week you see the latest piece running on a live link. You pay for a piece once you have watched it work, and it lands in your GitHub the same day. Then it goes live, on accounts in your name, with plain documentation. For thirty days afterwards I fix anything that breaks, at my cost. ## Terms You pay for a piece once you have watched it run on a live link, and never before that. Each paid piece goes into your GitHub the same day, with every account in your name, so by launch there is nothing left to hand over. There is no maintenance fee and no licence pointing back to me. The scope is frozen when the build starts. What the plan says is what gets built. If a piece turns out harder than planned, that is my problem rather than your invoice. Thirty days of fixes after launch are included, at my cost. You can stop at any finished piece and keep everything you have paid for. I take two builds at a time and never more. The next open slot is shown on the site. Everything is documented and in the client's repo from the first paid piece, built with widely used tools, so another senior engineer could pick it up. I am a registered sole trader in Vienna working under Austrian and EU law and invoicing from the EU. Builds are GDPR-compliant by default, with EU-hosted servers where it matters, and no client data is ever used to train anything. I sign NDAs on request. ## Compared with the alternatives With me, your prototype is what I build from; elsewhere you usually pay for a discovery workshop before any work starts. The person you had the call with writes the code, rather than a senior selling it and a junior building it. The price is fixed in writing before line one, rather than an estimate followed by a surprise. You see each piece running before you pay for it, rather than a reveal at the end. The code is in your GitHub from the first paid piece, rather than held until the last invoice clears. You message me directly instead of an account manager and then a ticket. Thirty days of fixes are included rather than sold as a support tier. An agency is worth it when you need five specialists at once. For one workflow you are mostly paying for meetings. The cheapest quote sometimes works out; when it does not, you pay twice, once for code nobody can use and again for someone to rebuild it. Cheap per hour is not cheap in total. ## Websites, a separate service A second, independent service, in [a section of the homepage](https://hanadkubat.com/#websites). It is not a tier of the software offer and is priced on its own. A website designed and built by Hanad and put live on hosting and accounts opened in the client's name. From EUR 2,000 net, fixed in writing before work starts. Included at the starting price: three pages of content; the Impressum, privacy policy and the other legal pages done properly for Austrian and German requirements; up to two languages, so English and German can run side by side; a website that works on phone, tablet and laptop; the first version of the text written and placed by Hanad; hosting and the domain set up in accounts in the client's name; analytics; and thirty days of fixes after launch at his cost. What raises the price: more than three pages of content, a content editor so the client can change text and pictures themselves, an online shop with products, cart, checkout and payments, or more than two languages. What does not raise it: how many people visit, a domain the client already owns, and which two languages are chosen. There is no paid scoping step for a website. The quote is free and given on a call before anything is invoiced, which is the main structural difference from the software offer. The terms are identical to the software builds: the client pays only after seeing the work running on a live link, hosting and every account are opened in the client's name, the scope is fixed in writing first, and the client can stop at any finished piece and keep what they have paid for. Text: Hanad writes and places the first version. Rewrites after that carry their own price, quoted and approved before he starts. After launch: optional care covering updates, backups and keeping the site online. Priced per website, with no published rate, arranged on the call or whenever the client asks. Not included at this price: brand identity from scratch, ongoing SEO or advertising campaigns, rewriting the text after the first version, and custom software features, which are the separate service described above. ## Technology TypeScript, Next.js, React and Node. Standard SQL databases. Stripe and merchant-of-record payment rails. Vercel and Cloudflare for deployment. LLM integration using Claude, Gemini and comparable APIs where a product needs it. GitHub for everything. I pick boring, widely used tools on purpose, because anything unusual becomes a hiring problem for whoever works on the code after me. Covered inside a build: payments, including cards, Apple Pay, PayPal, subscriptions, automatic invoices and VAT receipts, and retries on declined cards. Authentication, including one-tap Google and Apple login, magic links and two-factor. Hosting and deployment on accounts the client owns. Pages built so Google and ChatGPT can find them. An assistant that answers customer questions from the business's own data. And the long tail nobody budgets for: backups, uptime monitoring, error tracking, GDPR basics, cookie consent, transactional email, admin panels, audit logs, data export, translations, accessibility, offline support and handover documentation. ## How I work Prices go on the website. Fixed price, never hourly. You own what you have paid for. I show working software, not slides. Your prototype is the spec. Boring tools on purpose. I cut scope before I cut quality. Plain words, no jargon. Saying no is free. A guarantee should cost me something. ## Questions people ask ### What happens on the call? You show me the prototype, the sheet or the idea, in plain words. I tell you whether it fits, what I would build first, and where the price starts. What I will not do is quote the whole build on a first call. Quoting before scoping is guessing, and the correction always lands on your invoice. ### What does it cost, all in? Scoping starts at EUR 1,500 and is the first payment of the build price, not an extra. A build starts at EUR 12,000 net, fixed, in writing, and paid piece by piece. Afterwards the care plan is optional, from EUR 600 a month. Anything bigger gets its own quote. ### Why is EUR 12,000 enough for a senior engineer? Because you are paying one person directly, with no agency margin and nobody billing through a middleman. The trade-off is a limit I publish openly: one core workflow per build. ### Can my Lovable, Bolt or Bubble build be saved? Yes, and it is worth more than you think. It shows me exactly what you meant, which is the expensive part of any build. I use these tools every week, so I build on what you already have. Scoping tells you what to keep, including all of it when that is true. ### Do I own the code? All of it. Each piece you pay for goes into your GitHub the same day, with every account in your name, so by launch there is nothing left to hand over. No maintenance fee and no licence pointing back to me. ### Can the price go up halfway through? No. The price is fixed and the scope is frozen when the build starts. A new idea gets its own line and its own price, which you approve first. If a piece turns out harder than planned, that is my problem, not your invoice. ### How long does it take? It depends on what the one core workflow actually is, and your dates are set during scoping before you commit to anything. A rebuild with a working prototype moves faster than a build with payments and several user roles. As early as six weeks is realistic for a focused first version. ### What do you need from me? Twenty minutes a week to look at the latest piece on a live link and say yes or no, plus quick answers when something comes up. You do not write specs and you do not manage me. That is what you are paying not to do. ### What if you disappear, or get sick? You never pay ahead, so there is no money of yours to walk away with. Everything you have paid for is already sitting in your GitHub, documented, and built with tools any senior developer knows. If I am slow, it costs you time. It cannot cost you money. ### Why not offshore for a third of the price? Sometimes it works out. When it does not, you pay twice: once for code nobody can use, and again for someone to rebuild it. Most of the rebuilds I take on started that way. Cheap per hour is not cheap in total. ### Do you sign NDAs, and where does my data live? Yes, yours or mine. I am a registered sole trader in Vienna working under Austrian and EU law, invoicing from the EU. Builds are GDPR-compliant by default: EU-hosted servers where it matters, and no client data ever used to train anything. ### Which projects are not a good fit? Anything too big for EUR 12,000, like an app with subscriptions, several types of users and AI all at once. I build one app that works on every phone, rather than separate iPhone and Android apps. I do not work for company shares, and I cannot issue official security certificates such as SOC 2 or ISO. The app also needs one clear main job. ## Pages - [Homepage](https://hanadkubat.com/): the offer, the prices, the process, the comparison and the questions above. - [German homepage](https://hanadkubat.com/de): the same page in German, with its own [Impressum](https://hanadkubat.com/de/impressum) and [Datenschutzerklärung](https://hanadkubat.com/de/datenschutz). - [Pricing in plain markdown](https://hanadkubat.com/pricing.md), also [in German](https://hanadkubat.com/de/pricing.md). - [Blog](https://blog.hanadkubat.com/blog): articles for founders and technical leads on software due diligence, rewrite versus refactor, SaaS security, GDPR for AI, LLM evaluation and monitoring, and Postgres multi-tenancy. - [Impressum](https://hanadkubat.com/impressum) - [Privacy](https://hanadkubat.com/privacy) ## Elsewhere - [GitHub](https://github.com/hanadkubat) - [LinkedIn](https://www.linkedin.com/in/hanadkubat) - [X](https://x.com/HanadKubat) ## Contact Book the free 20-minute call from the [homepage](https://hanadkubat.com/).
