## Summary
I build consumer mobile apps from architecture to growth and monetization. At Openvibe I lead development of an iOS and Android app with 100,000+ downloads and 30,000+ MAU, covered repeatedly by TechCrunch. I took my own product, Meally, from idea to paying users in 50+ countries on my own, including design, market fit and go-to-market. I do my best work where engineering meets product: choosing what is worth building, building it and measuring whether it works.

## How I work with AI
I work primarily in Flutter, but in the age of AI I think the specific language matters less. What matters more is a well-built agent workflow and the ability to review the result and take it all the way to production.
- I split work across several agents in Claude Code: one builds the UI, another writes tests, another does the first code review.
- Agents work with my tools and data directly over MCP (Figma, analytics, the repository).
- I iterate on the result, review it and finish it: architecture and the final review stay with me.
- I ship whole features end to end, from the brief to release on the App Store and Google Play.
