Full-stack engineer building scalable web apps with measurable performance improvements.
KenyaWhat I'm looking for
I’m a Full-Stack Engineer with 4+ years of experience building high-performance, scalable web applications using React, Angular, .NET Core, Node.js, and TypeScript. I design and deliver production-grade systems that improve performance, reliability, and user experience.
I’ve architected RESTful APIs and data-driven platforms with PostgreSQL and MSSQL, optimizing query handling and caching to improve API response times by 30–40%. I also strengthen frontend performance through lazy loading, code splitting, and efficient state management (reducing initial load time by 45%), while using Docker, Azure DevOps, and CI/CD to cut deployment time by 50% and eliminate environment inconsistencies.
