NigeriaWhat I'm looking for
I am a Full Stack Developer with 4+ years building performant web, desktop, and mobile applications using React, Node.js, and Electron.js. I focus on delivering measurable improvements in performance, load times, and development velocity.
My work includes designing RESTful APIs, implementing CI/CD pipelines, and applying Agile practices to drive team efficiency. I have improved load times by 50%, optimized performance by 40%, and reduced development cycles across projects.
I have hands-on experience across the stack: React, Next.js, React Native on the frontend; Node.js, Express, AdonisJS on the backend; and databases including MongoDB, MySQL, and Firebase. I prioritize test coverage and reliability, achieving high uptime and robust API performance.
I lead frontend efforts on complex projects and have rebuilt legacy systems to modern stacks, improving UX and traffic. I am driven to join teams that value performance, scalable architectures, and continuous delivery.
