What I'm looking for

I’m looking for roles where I can build scalable, high-performance APIs and reliable systems—especially in cloud environments. I want to lead engineering delivery, optimize latency and database performance, and partner across frontend and backend to ship dependable products.

I’m a Senior Backend Engineer with 5+ years of experience designing and improving scalable systems and high-performance APIs used in production. I specialize in building frontend and backend systems that stay fast, stable, and reliable as usage grows, with a strong focus on performance, scalability, and reliability.

In my most recent role at MyCyber Clinics, I owned backend architecture for a telehealth platform serving 5,000+ users. I improved system performance by 30% through backend restructuring and database optimization, and I reduced API latency by over 25% to deliver more consistent real-time responses. I also designed and maintained REST APIs for secure healthcare data exchange and led a team of engineers to raise delivery timelines and code quality.

Across roles, I’ve continued to deliver measurable results—such as reducing API response time by 25% at Clivo and cutting system load time by 35% at RentNaija Homes through query optimization and backend improvements. I enjoy building modern interfaces with React and TypeScript as well, including contract work with enterprise-grade UIs and reusable component libraries, while applying my system-design mindset to integrations, security, and maintainability.
