IndiaWhat I'm looking for
I am a Senior Frontend Engineer with five years of experience building and scaling production-grade React and Next.js applications, focused on frontend architecture, performance optimization, and SEO-friendly rendering.
At Profolo I owned frontend architecture for core user-facing SaaS modules and built an AI-driven real-time interaction module; I routinely delivered high-quality, accessible dashboards with 95+ Lighthouse scores. Previously, as Lead Developer at Freeflow Venture Builder, I led frontend delivery across multiple products, increased engagement with 3D visualization tools, and improved retention through optimized state and animation flows.
I convert complex designs into pixel-perfect implementations, implement secure auth and performant API consumption, and establish reusable frontend patterns to reduce defects and accelerate delivery. I emphasize accessibility, technical SEO, and measurable performance gains in every project.
