What I'm looking for

I’m looking for a team where I can build scalable full-stack web applications, architect RESTful APIs, and improve performance with measurable outcomes. I value cross-functional collaboration, mentorship, and shipping production-ready features.

I’m a dynamic Full Stack Software Developer with hands-on experience designing and building scalable web applications. I specialize in JavaScript ecosystems, API architecture, and performance optimisation, and I enjoy delivering robust, maintainable code that works in real production conditions.

At CodeGallantX (Lagos, Nigeria), I built and maintained responsive web applications using React.js, Node.js, and RESTful APIs. I architected RESTful APIs that reduced integration time by 30%, and I optimized performance through profiling, code reviews, and debugging to achieve measurable loading time improvements.

I also designed and deployed automated testing suites using Jest and Mocha, cutting post-release bug rates significantly. I collaborate across design, backend, and QA teams, mentor junior developers on Git workflows and coding standards, and deliver full-stack projects from architecture planning to deployment.
