Web & AI
Next.js, NestJS and robots that run every day
N° 1Focus
I build products that are:
React Native and Expo apps live on the App Store and Google Play. I currently lead the rebuild of Pede.ai's three delivery apps: 1.5M+ installs, thousands of daily sessions and lower Android ANR rates. Six apps shipped over my career.
Next.js and NestJS systems on PostgreSQL: dashboards, marketplaces and a white-label platform used by 90+ fintechs. I have led squads of up to 6 engineers, from the data model to deploy, with code review and CI.
Integrations that work on their own: robots that read PDFs, classify with the OpenAI API and return schema-validated JSON. That is Licite Nordeste, every single day.
N° 2Process
The path every app of mine takes. Four steps, always in this order.
I talk to whoever pays and whoever uses it. I leave with the problem in one sentence, a sketched data model and a short list of what must exist in the first version.
Clickable screens before code. The main flow end to end in Figma, tested with the client, so mistakes are cheap and the interface is decided with real data.
TypeScript end to end. React Native with Expo in the app, Next.js and NestJS in the back, PostgreSQL, tests where things break and CI on every PR.
Signed build, Apple and Google review, staged rollout and crash and ANR monitoring. After the store, the product keeps going: metrics, tuning, next release.
