About Dorivaldo
Senior Full-Stack Engineer specializing in TypeScript, Node.js, React, and cloud infrastructure.
Over the years, I've built and shipped production systems for companies in Angola, Brazil, and Portugal, and I'm currently working with Novobanco through ITSector.
Outside of consulting, I enjoy building products from scratch. I'm the solo founder of WhaMail, a SaaS with paying customers, and I also created Simplr, a leave and absence management platform that's used in production at Novobanco.
I like owning projects from end to end—from architecture and development to infrastructure, deployment, and operations. Whether it's an MVP, a new feature, or a complex integration, I'm comfortable taking ideas from concept to production, even under tight deadlines.
If you have a project in mind, I'd love to hear about it.
