Hello, I'm
NJOHPRINCE JR.
FullStack Engineer · Senior Frontend Engineer · Technical Leader
Who I Am
I'm a results-driven FullStack Engineer with 5 years of experience building high-performance, production-grade web applications. Specializing in React.js, TypeScript, Next.js, and Node.js — I architect products from 0 to 1 and scale them to support thousands of active users.
Expert in component-driven architecture and performance optimization. I've led engineering teams, built accessible design systems, and consistently delivered measurable results: 40% Core Web Vitals improvements, 35% faster server response times, and 30% less technical debt.
Whether it's a greenfield product, a legacy modernization, or a team that needs a technical leader — I bring precision, ownership, and craft to every engagement.

What I Deliver
Performance Engineering
Obsessive about speed. I optimize Core Web Vitals (LCP, TTI, CLS), implement code-splitting, lazy loading, and intelligent caching strategies that deliver measurable 40%+ performance improvements in production.
Scalable Architecture
From MVP to enterprise-scale. I design component-driven systems, A11y-compliant design systems, and distributed microservice architectures built to handle growth with zero technical debt accumulation.
Technical Leadership
More than code — I build teams and cultures. Leading cross-functional squads in Agile environments, mentoring engineers, and translating complex product vision into precise, measurable engineering execution.
