Jamal Toyin

I am a backend software engineer focused on building scalable, secure, and performant APIs that power user-centric applications. I bring hands-on experience with RESTful API design, database optimization, and security practices like JWT authentication and RBAC.

At Briskit Agency I built robust APIs, improved system stability by 25% through debugging and refactoring, and optimized database queries to mitigate N+1 problems. As a backend intern at Netwalkers Nigeria I contributed unit tests that reduced production bugs by 30% and helped tune queries to improve response times by 20%.

My projects include collaborative work on an e-commerce system where query optimization improved server response time by 26% and a school management system implementing token-based authentication, RBAC, indexing, caching, and rate limiting. I emphasize clean code, performance monitoring, and secure design.

I hold a B.Sc. (Ed) in Computer Science and a backend software engineering certification from ALX Africa; I am adaptable, communicative, and committed to continuous learning and contributing effectively to dynamic engineering teams.
