Hello 👋, I'm
Hey, I’m João, a React & Next.js developer who helps businesses fix, optimize, scale, and build high-performance web applications. If your app is slow, buggy, struggling to scale, I can help you!
📌 What I Do Best:
✅ Fixing Bugs & Broken Code – Debugging, API issues, UI glitches that frustrate users.
✅ Optimizing Performance – Speeding up apps, improving SEO, and delivering a smooth experience.
✅ Scaling Web Apps – Making sure your app grows without downtime or technical limits.
✅ Building from Scratch – Creating fast, scalable, and future-proof React, Next.js and Vue applications.
📌 Why Work With Me?
🔹 I focus on real results, not just code. Your web app should run fast, handle traffic, and grow without breaking—I make sure it does.
🔹 I work fast and efficiently. No endless back-and-forth, no unnecessary delays—just solutions that work.
🔹 I don’t just fix problems—I prevent them. Whether optimizing an existing app or building something new, I ensure it’s scalable, maintainable, and built for the long run.
📌 Let's Talk
If your app needs fixing, optimizing, scaling, or building, let's connect.
