About Sequoya
Senior backend engineer, 10 years across fintech, education, and Web3. I started with C and systems
programming at 42 Paris; that foundation shapes how I approach performance, data integrity, and architecture decisions.
Core stack: Go, Node.js, PostgreSQL. I work well on data-heavy systems: complex migrations,
pipelines, schema design that holds up under load.
Remote-only. Fixed-price or day-rate. I own projects end to end.
