GHASSAN GAIDI

backend & security engineer — money & secrets, proven correct Rust · Python · TypeScript

ghassan.tech email Bizerte, Tunisia Open to remote roles

About

Final-year ICT student (graduating June 2027) who builds and ships backend and security software — in Rust, Python and TypeScript. I care about systems that are correct by construction and verifiable by CI: encrypted protocols with formal models, APIs with real auth and rate limits, and products that actually get deployed. Multiple verified high-severity vulnerability reports on HackerOne. Published SDKs for an AI-agent memory API to npm and PyPI.

⚡ Available for internships, part-time & contract engagements (20–30 h/wk) immediately — full-time from June 2027. Open to relocation.
