Description

Frontend Senior with 5+ years of experience, specialized in React, Next.js, and TypeScript. I build high-performance, scalable web applications with a strong focus on user experience and clean architecture.

Beyond client work, I’m a SaaS product builder: I created and launched PDFToolsHouse (online PDF toolkit), GrowinTools (developer productivity tools), and Vocaa (voice notes app). This entrepreneur mindset means I understand your business goals as deeply as your technical challenges.

Available for Tech Lead, frontend architecture, and React/Next.js development missions. Let’s discuss your project.
