About
Full-Stack & Mobile Engineer
I design digital products that stay consistent across platforms. From mobile to web, I build experiences meant to be performant, maintainable, and able to evolve with the product. I care as much about what the user sees as what makes it all run underneath: fluid interfaces, reusable components, solid APIs, systems built to hold up as the product grows. The goal stays simple, turn an idea into a reliable product, with the architecture needed to go further.
About
Architecture & High Tech
I work on systems where the technical choices actually matter: real-time backends for e-commerce, securing transactions between mobile money and banks, integrating AI into CRMs. I design the architecture, structure the APIs and components so the system stays readable to maintain and can handle growth without turning into spaghetti code. Automation is part of the deal too; less friction to ship, test, and evolve a product over time.
About
Background & Method
Mathematics at the University of Lomé, Computer Science at the University of the People, full-stack certification at Epitech: three programs, three angles, one thread running through them, understanding a problem before writing a single line of code. In practice, that means a complete, well-managed development cycle: design, development, testing, CI/CD, deployment, all in Agile, with user experience treated as a guiding thread rather than a final touch.
