About Me

I'm Symplice BONI, a backend engineer with a deep focus on building reliable, scalable server-side systems and APIs that power great products.

My daily stack revolves around Java — Quarkus and Spring Boot — and Node.js. Beyond coding, I specialize in Technical Project Management. I have a proven track record of leading Agile teams, ensuring high-quality delivery while mentoring developers to reach their full potential.

When I'm not writing backend logic, I'm exploring new technologies, contributing to open-source, or sharing knowledge with the developer community.
