What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth in backend development and cloud technologies.

I am a backend engineer with over 5 years of experience in building scalable, distributed systems using Node.js, TypeScript, and NestJS. My journey has been marked by a proven track record in designing RESTful APIs, migrating monolithic architectures to microservices, and implementing CI/CD pipelines on platforms like AWS and DigitalOcean. I am passionate about clean code, system architecture, and team leadership, which has allowed me to contribute effectively to various projects.

At Nazza, I led the refactoring of a monolithic architecture into microservices, significantly improving system availability and scalability. My role involved building high-performance APIs that processed over 1 billion Naira in transactions. I also established monitoring and alert systems for real-time incident response, showcasing my commitment to operational excellence. My experience at Medtech Africa further honed my skills in architecting and deploying infrastructure, where I successfully launched educational tech initiatives that increased regional outreach by 40%.
