You vibe-code the business logic. I make sure your app is still standing two months from now — stable, secure, and with your data intact from day one.
How it works
You know what your business needs — so you build exactly that. You shape the process, because nobody understands your business like you do.
I know what good code needs to look like. I keep it clean and handle the servers and the rest of the technical side — so nothing breaks the day real users show up.
Building something just for yourself? You probably don't need me. But the second other people start relying on it, data integrity, uptime, and security suddenly matter a lot. Let me help you get it right from the start — way cheaper than cleaning up a mess later.
About
A lot of developers are nervous right now — AI is taking over parts of their work. Honestly? I love it. It means good ideas don't die behind a crazy invoice anymore.
Yes, I'm a developer too. But I also run businesses, so I get it. I've watched a single button cost €500 and a website cost thousands. It genuinely makes me happy when people can just build the simple stuff themselves.
In a way, AI took my old job — I used to take prototypes from zero to a hundred. But the new way is better: you understand the business, so you build it. I understand the tech, so I make sure it actually holds up.
Already built your thing and something's nagging you? Happy to jump in and take a look. I promise my first reaction won't be "rewrite the whole thing." But if it turns out to be my second reaction — promise me you'll at least hear me out. :)
Vibe freely — I'll keep it standing.
A fair warning
The popular starter stack — Vercel + Supabase and friends — is genuinely great for getting started. Idea to working app in a weekend. For a prototype or a tool you use yourself, perfect.
But nobody mentions the catch: the same speed that makes month one feel like magic makes month four feel like a brick wall.
Perfect for testing an idea or building something for yourself.
The boring, proven setup programmers have used for decades — for apps that need to keep growing for months and years.
That's the point: vibe-coding piles up technical debt fast, and fixing it eventually costs more than building it did. Neither stack is wrong — the mistake is using the fast one for a job that needs the lasting one. If your app's going to keep growing, let's lay the foundation now, while it's cheap.
Services & pricing
Bigger project, bigger price — obviously. But we agree on scope and cost up front, so you always know exactly what you're paying for.
Credited in full if we go on to work together.
One proper call. We go through your app and you get a straight answer — where the real risks are and what to do about them.
Includes a penetration test — handled by my partner.
I read through your code and review the server and database setup. A bug can be fixed — broken data can't be brought back. That's what I'm protecting you from.
6-month contract. You get my architecture foundation to build on.
You vibe-code the business logic, I take care of the rest. Servers, security, backups, and a good night's sleep — all covered. It doesn't last forever: once the architecture is in place, you become independent.
Now I'm the technical partner for Gold Adam — their team vibe-codes their internal app, and I keep the tech reliable and the data safe.
A penetration test (pentest) comes with the security checkup — it's done by my partner, who's a specialist in it. I handle the code and infrastructure side.
