You will get Frontend API Integration & Performance Optimization (Next.js / React)

Project details
I bring 6 years of experience at Deloitte delivering frontend solutions for high-traffic public and private sector platforms, where reliability, performance, and maintainability are critical. My background means I don’t just “connect APIs”, I build integrations that are robust, scalable, and production-ready.
I specialise in Next.js and React, with a strong focus on performance optimisation. This includes efficient data fetching, reducing unnecessary re-renders, optimising Core Web Vitals, and ensuring API-driven UIs remain fast and responsive as applications scale.
My approach is practical and developer-led. I write clean, well-structured code, document decisions clearly, and test integrations thoroughly to avoid regressions. I’m comfortable working within existing codebases or designing new integration patterns that align with modern frontend architecture.
If you need a frontend engineer who understands both API design and real-world performance constraints, I bring enterprise experience and apply it directly to your product.
