Project details
Frontend bugs cost time, users, and revenue. React and Next.js issues around rendering, state, and data flow can silently break UX.
I work daily in React and Next.js and fix production issues across SaaS apps:
• Broken UI components and layout issues
• React state, hooks, and lifecycle bugs
• Next.js routing, hydration, and SSR errors
• Performance bottlenecks and unnecessary re-renders
• API integration bugs and frontend data mismatches
• Build, deploy, and environment-specific issues
My process: reproduce the issue reliably, identify the root cause, apply a clean minimal fix, and verify across browsers and breakpoints.
The basic package covers one reproducible issue. The 24-hour window starts once I have repository access, reproduction steps, and any required credentials. If the issue depends on an unavailable third party, I will tell you before you pay for a fix.
Share the issue and repo access. I will confirm scope before starting.

Concierge Medical App - UI Improvements
Working with Noman was an absolute pleasure. He not only brought top-notch technical skills but also really understood the complexities of building an AI-based healthcare platform. He combined precision with creativity, built a solid scalable system, and even suggested improvements that made the product better than I had imagined.
Communication was smooth and professional, deadlines were always met (often early), and he was super responsive despite different time zones. I couldn’t recommend Noman enough; he truly turned a complex idea into a working reality and I’d gladly work with him again.

Frontend Web Developer Needed to Complete Existing Website
Working with Noman was an absolute pleasure. He was incredibly responsive, highly capable, and lightning-fast with every task. His communication was crystal clear, and he always kept me in the loop—even when I was wondering if he ever stopped working! His attention to detail, problem-solving skills, and professionalism made the entire project smooth and stress-free. If you’re on the fence about hiring him, don’t be—Noman is the real deal. I would hire him again in a heartbeat!
