Backend Developer · End-to-end systems
Javier Zader
I build backend systems in Java, Go and Rust — from industrial platforms running predictive ML on edge hardware to AI-powered dev tools that write and review code. 20+ years in tech.
apigen — a tool I built that turns a SQL schema into a complete, running Spring Boot API.
About Me
I build software that holds up in production
My Journey
I've spent 20+ years around technology. It started in IT support and hardware maintenance — which taught me how systems really work under the hood. Then came several years running a farm, where a bad call costs you a season, not a rollback.
That mix of hands-on experience is what pulled me back into software. Now I build systems end to end in Java, Go and Rust — I own the whole stack, from the database to the deploy — and I'm always picking up something new.
My Approach
- Scalable, modular architecture
- Clean, maintainable, well-documented code
