What I'm looking for

I’m looking for a role where I can build fast, polished React/Next.js experiences, collaborate with engineers on real-time features and APIs, and grow by shipping production-grade projects with measurable performance improvements.

I’m a Freelance Frontend Developer (Remote) building user-focused web experiences with React and Next.js, with a strong performance mindset. I delivered 2 client landing-page projects and improved core web vitals scores from ~50 to 90+ on Lighthouse using lazy loading, code splitting, and CDN caching.

I also enjoy building the systems behind the UI—like real-time monitoring and dashboards. In Inspekt, I engineered a WebSocket bridge, built a multi-tenant Next.js dashboard with API key management, and shipped an open-source NPM SDK for AI-powered root-cause analysis and anomaly detection. I’m currently developing Webless Finder to create an auth-free lead tool with IP-based rate limiting (5 scans per 24-hour quota).
