Website, web system and app development in Petrolina, Brazil
I'm a full-stack software developer with 6 years of experience, based in Petrolina, Brazil. I work in person with companies from Petrolina, Juazeiro and the São Francisco Valley, and remotely with clients across Brazil and abroad. No middlemen: the person you talk to is the person who writes the code.

What I do
Web systems
Admin dashboards, marketplaces, white-label platforms and custom systems in Next.js and NestJS on PostgreSQL. From the data model to deploy, with tests and CI.
Android and iOS apps
React Native apps shipped to the App Store and Google Play. Six apps so far, including delivery apps with 1.5M+ installs and white-label fintechs.
AI integrations
Robots that read documents, classify them and return structured data with the OpenAI and Anthropic APIs. Automation for routines that still depend on copy and paste.
Maintenance and evolution
I take over existing systems and apps: bug fixes, performance, new features and store releases, delivered in small reviewable PRs.
Where I work
In person in Petrolina, PE, and Juazeiro, BA. Remotely, anywhere in Brazil and abroad, with written communication in the Brasília time zone.
