Résumé
Senior full-stack engineer, in software since 2010. Where I worked, what I work with, what is public — and the same as a PDF.
Experience
Independent — Founder & Product Engineer
Roughly forty builds solo since April 2025 — three I'd defend in detail.
Product, code, infra, ops and billing — using AI-assisted workflows to compress build time while owning every architecture and review decision myself. Shipped: Atlano (habit, goal and life-balance app), games and trainers, a web book, and research on 272 dossiers of the self-made wealthy.
Vereign AG — Switzerland
Owned mobile end-to-end on a Zero-Trust authentic-communication platform.
React Native + Expo apps shipped to the App Store and Google Play. Built the Personal Data Wallet UI on Credo-TS, the Outlook plugin (Microsoft AppSource) and a Chrome extension. Contributed to a Swiss healthcare Zero-Trust project (IPFS, self-signed cert identity) on the frontend/integration side. Upstreamed fixes to Credo-TS.
Mobilabsolutions — Germany
Kept a complex production app at 80%+ test coverage.
Frontend on a complex web app against a Python micro-service backend.
Mozio — USA
Worked on a live AngularJS → React migration in production.
Migrated page-by-page in production, with both stacks running side by side. Built new components and post-migration features.
SimbirSoft
Junior to senior in 3 years, across 30+ projects.
Very different stacks (JS, AngularJS, C#, Java, PHP, Ruby on Rails, desktop). Frequently rotated onto troubled projects to stabilize delivery.
Stack
What I work with day to day. I ramp on new tools quickly when a project needs it.
