About

Hi, I’m Jayzelle Yanga—a full-stack engineer who loves turning complex problems into clean, scalable web applications. Over 8+ years, I’ve designed, built, and deployed high-performance apps using React, Next.js, Angular.js, Vue.js, Node.js, and Express.js across various industries.

I’ve led cross-functional teams, introduced CI/CD pipelines and automated testing, and partnered with designers and product managers to translate ideas into polished user experiences. I’m passionate about performance, accessibility, and writing robust APIs (REST/GraphQL) that scale.
