Faster React & Next.js apps, even when AI wrote the code

Work
AI tools help teams ship SaaS products quickly, but the code they generate often slows the app down: pages that load late, clicks that lag, screens that freeze on phones. I'm a Senior React Performance Engineer. I find what is causing the slowdown and fix it, so your product feels fast to real users and holds up on Google's Core Web Vitals.
I've applied this in the real world:
- At Linitani, I spearheaded development to bring new efficiency and transparency to the agriculture industry.
- I audit and repair performance regressions in AI-generated React and Next.js code, from slow page loads to laggy interactions, without rewriting the whole app.
I'm also passionate about building the developer community, having personally mentored and trained over 50 aspiring front-end developers in ReactJS at Binar Academy. I thrive in fast-paced environments where I can learn quickly and deliver results.
