You will get React & Next.js bug fixing
Project details
I specialize in fast, reliable React.js and Next.js bug fixes the kind of issues that are easy to overlook but frustrating to live with: broken UI states, failed API integrations, performance bottlenecks, hydration errors, and hard-to-reproduce edge cases. What sets me apart is that I don't just patch the symptom I trace the actual root cause before touching your code, so the fix holds up instead of resurfacing later. I write and run tests around the fix to catch regressions, and I communicate clearly throughout so you're never left guessing about progress. Whether it's a single stubborn bug or an app-wide health check, I treat your codebase with the same care I'd want for my own.

I'm a SaaS MVP Developer and Full-Stack Engineer who focuses on solving software problems, not just writing code.
I help startups and businesses build, fix, improve, and scale SaaS products and web applications from new MVPs to existing products that need debugging, new features, integrations, or performance improvements.

👉 Understand the problem. Find the right solution. Build it properly.
I don't immediately jump into coding. I first understand what is going wrong, why it is happening, and what solution makes the most sense for the product and business.
