Hey! I’m Berenis MASSAMBA
Full-stack developer with a DevOps culture. I build web applications end to end, from code to production.
About
Full-stack developer based in Brazzaville, I design modern web applications and I also take care of what comes after going live: containers, releases, databases, monitoring. My path started on the systems side, administering servers at SIAT, before moving to product development. That double background changes the way I code: I think about migrations, response times and error logs while writing the feature, not three months after it ships. I work mainly in TypeScript with React and Next.js, in Node.js and PostgreSQL on the server, and in PHP with Laravel or Symfony when the project calls for it. I also teach HTML, CSS and JavaScript at the GOOD TECH training centre.

Writing
What I learn while building: what held up in production, what broke, and why.
Containerising a Next.js app without a bloated image
18 Aug 2026A multi-stage Dockerfile, the standalone output, and the few traps that take an image from 1.2 GB down to 180 MB.
#Docker#Next.js#DevOpsViewWhy I model the database before the interface
02 Jul 2026Starting with the screens gives you something to show faster, and something much slower to fix.
