[02] About

I’m Darryl-Win LOGOSSOU, a software developer with a production-oriented mindset. I build robust applications across backend and mobile, and on the web too, from architecture design to feature implementation.

My experience spans backend architecture, mobile development, and web applications. I work with Spring Boot, Nest.js, Flutter, and Next.js to turn complex requirements into reliable products with clean, maintainable foundations.

I also use AI in my workflows to move faster on research, prototyping, and reviews, while keeping architecture decisions and quality checks in my own hands.
