for safe software
I'm Pascal Perrenoud, a software engineer based in Yverdon-les-Bains, Switzerland, with an MSc in cybersecurity. I build backends and systems in Rust and TypeScript, and through Codexa I build and run software for clients and for my own products. Available remotely, as a contractor or as an employee.
Selected projects
Feezio
A practice-management app used every day by a physiotherapy practice.
Theca
Self-hosted cloud storage. A Rust server with content-defined chunking onto S3, and a Rust client compiled to WASM.
what2do.ch
Cultural events in French-speaking Switzerland, gathered by a scraping pipeline and searchable on a map.
What I do
Rust systems and backends
Servers, network protocols and performance-critical code.
Web backends and apps
APIs, databases, and the front-end when the project needs one.
Security, built in
Secure code review and applied cryptography.
Who am I?
Before going independent, I spent three years in research and engineering: fault-injection countermeasures for cryptographic hardware at CSEM, then post-quantum cryptography and satellite protocols at HEIG-VD.
Let's work together
A project that needs building, a codebase to secure, or a role to fill? Tell me about it.
