Over mij
Most apps fail in production. I build the ones that don't.
4 years shipping Flutter apps and NestJS backends that handle real users, real traffic, and real business operations — including a transport platform with 50+ drivers and 5,000+ active users.
I also integrate AI into products that actually need it — chatbots, workflow automation, backend intelligence — not just AI for the sake of it.
Clean architecture. Clear communication. You'll always know what's happening and what's next.
Tell me what you're building — I'll tell you exactly what it takes to do it right.
