You will get Fix Bugs in React, Next.js, Node.js & JavaScript
Project details
Stuck with a bug that's blocking your project? I'll fix it fast.
I'm a Full Stack Developer with 4+ years of experience building
SaaS platforms, web apps, and e-commerce solutions. I specialize
in debugging React, Next.js, Node.js, and JavaScript — from broken
layouts to API failures to console errors.
What makes me different:
→ I don't just patch the symptom — I fix the root cause
→ I test across browsers and devices before delivery
→ You get clean, commented code you can actually understand
→ Fast turnaround — most fixes delivered within 24 hours
What I fix:
→ React/Next.js: hooks, state, routing, rendering issues
→ JavaScript: logic errors, async bugs, DOM issues
→ Node.js/Express: API errors, server crashes, middleware
→ CSS/HTML: layout breaks, responsiveness, cross-browser issues
I'm new to Upwork but not to development. You get senior-level
debugging at starter prices while I build my reputation here.
Message me first if unsure which package fits your bug — I'll
point you to the right tier so you're never overcharged.
