@seliwanoff
Frontend Engineer specializing in React and Next.js, building fast, scalable interfaces that help startups launch and grow products.
NigeriaWhat I'm looking for
I am a frontend engineer focused on building responsive, accessible, and high-performance web applications using React, TypeScript, and modern CSS frameworks. I design and implement reusable component libraries, optimize load times, and ensure WCAG-compliant experiences.
I've led web frontend development for cross-border payment platforms and fintech products, integrated payment and wallet APIs, and built data-driven interfaces and mapping visualizations for mining and exploration platforms. My work has reduced load times, improved usability across devices, and accelerated project delivery through reusable components and performance optimizations.
I collaborate closely with product, design, and backend teams, mentor junior engineers, and apply practical SEO, accessibility, and security best practices to deliver reliable, user-focused web solutions that scale.
