Ugochukwu Meshach

I’m a results-driven Full-Stack Software Engineer with hands-on production experience building scalable, high-performance web applications using React, Next.js, TypeScript, Node.js, Express.js, and MongoDB. I love clean architecture, secure coding practices, and systems that scale with measurable impact.

During my Full-Stack Software Engineer internship at Pluralcode Academy / Sage Institute, I architected and implemented a Node.js/Express.js backend infrastructure supporting 500+ concurrent active users with 99.9% uptime. I delivered secure RESTful APIs with JWT authentication and role-based access control (RBAC), optimized MongoDB queries and indexing to reduce average API response times by 40%, and improved system throughput by 40% through debugging and query profiling.

I build quality into everything: unit/integration testing with Jest (80%+ coverage), CI/CD pipelines on Vercel and Railway (reducing manual deployment time by 60%), and accessible front-end components aligned with WCAG—improving engagement by 25% while reducing UI support tickets by 30%. I’m also AWS-certified in Generative AI (AIP-C01), and I apply that mindset to performance monitoring, Core Web Vitals optimization, and production-ready delivery.
