About Claire

Douala, Cameroon Master's in Data Science, in progress

I'm a backend-focused developer with hands-on experience designing and building secure REST APIs for real business applications. From mobile payment systems to internal authentication portals. My foundation is Java and the Spring ecosystem (Spring Boot, Spring MVC, Spring Data, Spring Security), paired with a good instinct for performance, security, and maintainability. I'm comfortable in Agile teams, working closely with product and frontend engineers to ship things that hold up.

I'm currently a Backend Developer at Yata Experts, while completing a Master's in Data Science and a Data Scientist certification on DataCamp, growing my engineering practice toward data-driven decision making.

Outside of work

A few things that keep me balanced and curious.

Staying active

Regular workouts are non-negotiable for me. They're where I clear my head and come back sharper.

Music

There's always something playing while I code. It's how I get into flow and stay creative under pressure.

Personal growth

Books, podcasts, and a lot of reflection. I like being intentional about how I grow, as an engineer and beyond.

Healthy routines

Sleep, nutrition, mindful breaks. A balanced routine is what makes consistent, high-quality work possible.

Anime

My go-to way to unwind. I love stories built around strong world-building and character growth.
