My Journey

I'm Yaji NONFON, a freelance backend developer specializing in building secure REST APIs and complete web applications. My core strength is everything that makes your product reliable, secure, and scalable. But I also deliver clean frontends when the project calls for it.

My journey started at Accra Institute of Technology (GHANA) where I studied Computer Science and built a strong foundation in software development. Accra Institute of Technology (AIT), During my studies, I participated in a training program at Techten Planet Ghana, which allowed me to strengthen my skills in Node.js, Express.js, and REST API development.

From there, I went freelance and started delivering real projects. I built Mp Recharge, a mobile-first financial platform with African Mobile Money integration and 100+ active users in production. Then a complete billing SaaS that I use myself every day to manage my own freelance clients.

Every project I deliver is treated like a real product: deadlines respected, clean code, clear communication.

What drives me is simple: using technology to solve real problems and building things that people actually use.

Outside of coding, I'm always learning something new, experimenting with ideas, or building tools that make life a little easier. Growth matters to me both as a developer and as a person.

I'm currently open to freelance work, new missions, and any opportunity to bring ideas to life through code.
