Guillaume in a few words

I am a backend and data engineer with ops skills and some interest in front-end development. I am able to understand a general computer science problem with potential scalability issues, design and discuss solutions potentially involving distributed systems and databases and implement them in a professional fashion.

This usually means:

developing proof of concepts
setting up initial projects, CI/CD, …
coding features with their different test families
writing deployment code for a cloud infrastructure
incrementally adding and fixing the initial result
reporting and communicating on work done and to be done

My daily work habits include ensuring I write simple clear and efficient tested code, version and document it, set or improve the team’s tooling regarding code quality, automatic delivery and deployment. I also check the software I work on include reporting and alerting and I regularly troubleshoot and fix problems that arise in live environments. Depending on my position in the team I pair with team-mates, submit/review code or simply try to learn as much as possible or improve knowledge sharing.

I am interested in Clojure, TypeScript/Node.js, Go, Rust backend/data long- term projects and work as a contractor. I do not wish to work with Java nor Scala anymore.
