John Tasie,
Product-focused frontend engineer building scalable, high-fidelity web applications.
Product-focused Frontend Engineer with 4+ years of experience driving frontend architecture for global clients across 5+ countries. I build scalable web applications where high-fidelity UX meets rigorous engineering standards.
I thrive in collaborative environments, translating complex Figma designs into pixel-perfect solutions that move the needle on business goals. My toolkit is built for the modern web with React, Next.js, and TypeScript, GraphQL and Supabase. I consistently expand into PostgreSQL and MongoDB to support end-to-end data integrity and optimized workflows.
