Senior full-stack software engineer from João Pessoa, Brazil. Since 2020 I've been building and evolving enterprise systems with Java/Spring Boot and Angular, and since 2022 I've led development teams technically while staying hands-on with the code.
Outside my day job, I'm the founder of IF Dev Tecnologia, where I build my own products and custom apps and systems:
- Conta Certeira (live): free Brazilian calculators that run in the browser, no sign-up, mobile first.
- spring-specification-tools: builds Spring Data JPA Specifications with less boilerplate. Published on Maven Central.
- ng-mask: input masks for Angular forms. Published on npm.
- spring-auth-service: OAuth2 and JWT authentication service with Spring Boot.
- angular-app: Angular starter with login, users, groups and permissions.
