About

I’m a Frontend Engineer where I lead frontend initiatives focused on building scalable, high-impact, and accessible user experiences. In my role, I’ve taken ownership beyond my title, acting as the lead frontend engineer for accessibility initiatives and mentoring multiple engineers across the team. I work closely with design, product, and backend partners to translate complex requirements into clean, performant, and user-centric interfaces. My day-to-day work involves solving non-trivial UI problems, optimizing rendering performance, and implementing robust frontend architectures that scale with product growth. I care deeply about engineering fundamentals, clean abstractions, and writing code that other engineers actually enjoy working with. Having often been the only frontend specialist in the room, I’m comfortable setting best practices, reviewing designs critically, and raising the bar for frontend quality across teams. Always open to conversations around frontend engineering, scaling UI systems, and building products that last. Tech focus: React, Next.js, TypeScript, Frontend Architecture, Performance Optimization, Accessibility (WCAG), System Design (Frontend) 🔺 Visit my portfolio → www.sayanmaity.in 🔺 You can always reach out to me → sayancr777@gmail.com
