What I'm looking for

As a software engineer with experience improving app performance and developing scalable platforms, I'm interested in roles that allow me to use my skills and work independently or as part of a team. My experience building and managing products may suggest a potential interest in entrepreneurship. Ultimately, my career goals and preferences will depend on my individual priorities.

I am a seasoned software engineer with over a decade of experience working with startups, agencies, and small businesses. I possess proficiency in modern development tools and methodologies, and I exhibit adeptness in both autonomous project management and collaborative teamwork.

I hold a BTech in Computer Science from the Federal University of Technology, Owerri, where I excelled with a 4.35 GPA. During my studies, I undertook courses such as Algorithms and Data Structures, Operating Systems, Networking, and Logic Design.

In my professional career, I have successfully improved app performance, built highly scalable SMS platforms, led the development of a flight platform, and improved platform retention through migrations and new designs. I possess proficiency in the latest development tools and techniques, and I have a strong ability to work independently and as part of a team.

Apart from my professional experience, I have also developed a full-stack mobile app called Coincord. The app enables users to easily spend crypto assets and currently boasts of over 700 users and $36,000 in transaction volume.
