What I'm looking for

I'm looking to build user-facing web and mobile products end to end, owning reliable interfaces, offline behaviour, APIs, testing, CI, releases, and production health.

I've founded Jornal, a workforce-management SaaS with a React/TypeScript web app and iOS/Android app sharing a typed domain core over PostgreSQL. I built its test and CI foundation, including 41 Vitest suites and 40+ database integration scripts validating real migrations, RLS, triggers, immutability, and concurrency.

As co-founder of MMENTO, I build an offline-first React Native consumer app with video streaming, GPT-4 streaming assistance, subscriptions, and weekly App Store and Google Play releases. I own the parts users feel when the network drops, along with crash monitoring, testing, and production health.

I've also shipped Japify solo in three months, maintained internal operations software at Fuenlegal, and led game teams whose work reached Steam and university classrooms. I use Claude Code and Codex daily and care about automated checks over hope.
