About Yann

I have 10 years of experience as a software developer. I started in scientific programming and high-performance computing, and today I specialize in back-end development, API specification, and data processing.

My favorite technologies are Go (the language) and SQL (particularly PostgreSQL, SQLite, and BigQuery).

From scientific laboratories, I learned rigor and perseverance. In high-tech startups, I learned versatility and agility. In production, I learned to design, develop, deploy, and monitor large applications.
