About

Building software that works

I'm David Saliba — a freelance software engineer with a Computer Science degree from Germany. My focus is on full stack web development, Python automation, and Solana smart contracts.

I care about doing things properly: understanding the problem, architecting a clean solution, and delivering it on time. No over-engineering, no shortcuts.

Whether it's a SaaS platform, an automation pipeline, or a secure on-chain program — I bring the technical depth and reliability to execute it right.
