I'm a Frontend Developer with 2+ years of experience building enterprise-grade web interfaces. At DEPT®, I worked on AU Small Finance Bank's public-facing site serving millions of users — implementing site-wide search, voice search, and the Branch Locator.
At Rejolut, I built XPharms Xchange (a Next.js B2B platform achieving 92+ Lighthouse scores) and Research Assist, an internal AI copilot for ICRA's financial analyst team.
