Web and mobile app development, end to end.

What I build

• Mobile apps for iOS and Android with Flutter, from the first screen to the store release.
• Web apps with Angular or Vue on the frontend and Node.js or NestJS with Postgres behind it.
• AI features on AWS Bedrock, such as assistants that take real actions, with guardrails.
• Automation and tooling, such as build and release pipelines.

How a project runs

1. Brief: you describe what you need, on a call or in writing.
2. Scope: within 48 hours you get a written scope with timeline and price, as a fixed price or time and materials.
3. Build: a demo every week, so you see progress and can change course early.
4. Handover: the code and the documentation belong to your team, plus 30 days of support.

Why one senior engineer

No project manager in between and no juniors learning on your budget: the person you talk to is the person who writes the code. For an MVP or a clearly scoped product, that’s often faster and cheaper than an agency.
