Hello! I’m Rivo Rahajason
Ships things that actually work…
Because a system nobody can maintain isn’t really shipped.
I’m a Full-Stack Developer
Currently, I’m a Lead Full-Stack Developer atTF1
An engineering graduate with over a decade of experience building full-stack systems in .NET, Angular, and React — from healthcare SaaS to newsroom tooling to fine-tuned language models. I care about clean architecture, reliable systems, and shipping software that lasts.
