Sylvester Ojay
@sylvesterojay
Fullstack developer building scalable, user-focused web apps with React, Node, and performance-first UI/UX.
NigeriaWhat I'm looking for
I’m a results-driven Fullstack Developer with 2+ years of experience building scalable web applications using React.js, Next.js, and Node.js. I focus on turning product goals into intuitive UI/UX and fast, reliable experiences that improve real business outcomes.
Across my roles, I’ve helped lift performance and engagement—proving impact by increasing user engagement by 30% and sales by 40% through UI/UX design and performance optimization. At GoMyCode, I reduced page load time by 35% using code optimization and lazy loading, while delivering an e-commerce frontend with React and Redux.
On the backend side, I build secure, production-minded APIs with Node.js and Express.js, including RESTful APIs and JWT authentication. I also integrated payment and data services (including Amazon product catalog integration and payment APIs), and I’ve worked with real-time analytics and dashboards to improve operational efficiency.
I bring a unique perspective from my graphic design background, which strengthens my attention to user-centric design and visual clarity. Whether I’m building marketplace interfaces that increased sales conversion by 30% or creating student dashboards for 500+ users, I aim for clean architecture, strong collaboration in Agile sprints, and measurable results.
