Web apps & SaaS
Dashboards, platforms and SaaS products in React & TypeScript — fast, responsive and built to scale.
Web & native app development
Ship a real product — web and native, end to end.
I design, build and run full products: web apps and native mobile apps, with the database, accounts and cloud infrastructure behind them. One senior engineer who owns it from first spec to production — not just the code.
- From 4 weeks to production
- Web · iOS · PWA
- Database, accounts & infra included
For founders and teams who need a real product built and shipped — not a prototype that stalls.
What I build
Full products, not just screens
Everything a real app needs to go live and stay alive — designed, built and wired together by one senior engineer.
Native & mobile
iOS and cross-platform apps, plus installable PWAs — one product on every screen your users are on.
Backend & database
APIs, real-time data and databases — the engine behind your product, designed to last and to scale.
Accounts & auth
Secure user accounts, roles and permissions — sign-up, login and everything that protects your users’ data.
Cloud & infra
Hosting, CI/CD and monitoring — the cloud setup that keeps it running, deployed and maintained, not handed off broken.
Specs & architecture
We turn your idea into a clear spec and a solid architecture first — so the build is fast and nothing important is missed.

Visit site How it works
From idea to production
Most builds ship a first version in 4–6 weeks; larger products grow over a few months. Either way, you see working software every week.
01
Spec & scope
We turn your idea into a clear spec, a feature list and an architecture. You get a fixed scope, timeline and price before we build.
02
Design & architecture
I design the screens and the system behind them — database, accounts and APIs — so the product is solid from the foundations up.
03
Build in sprints
I build in short iterations with regular check-ins. You see and use working software every week, not only at the end.
04
Launch & scale
We ship to production — web and app stores — and I stay on to support, improve and scale it as you grow.
Pricing
Top-tier product, priced to scope
Builds start from €5,000. From there it depends on what you’re building — the scope and the complexity. We work out the real number together on a short call.
MVP
Your idea, live and usable — the core that proves it.

A starting point, not a quote — the real price depends on scope and complexity, and comes from a discovery call. Larger products are billed in milestones.
FAQ
Questions, answered
How long does it take?
A focused MVP usually ships in 4–6 weeks. A full product across web and native typically takes 2–3 months. I work in weekly sprints, so you’re using working software long before the final launch.
Web app, native app, or both?
Whatever fits your users. I build web apps, installable PWAs and native iOS apps — often one product across all of them, sharing the same backend. We decide the right mix in the spec stage.
Do you handle the backend and database too?
Yes — that’s the point. I build the whole product: front-end, backend, database, authentication and the cloud infrastructure. One person who owns how it all fits together.
Who owns the code and the product?
You do — completely. You get the full codebase, accounts and documentation. Everything is built on open standards with no lock-in to me.
Can you join an existing team or codebase?
Absolutely. I regularly pick up existing products to add features, fix issues or rescue stalled builds. An audit is often the best first step.
What happens after launch?
I don’t disappear at launch. I can stay on as your product partner — adding features, monitoring, scaling and supporting it — exactly as I do with my own products in production.
