Over the past 5\+ years, I’ve worked on enterprise systems that required strong architecture, thoughtful UX, and measurable performance improvements\. At Infosys, I helped build a KYC workflow platform processing 500K\+ annual submissions, designed validation\-heavy user flows, and improved testing reliability with 85%\+ unit coverage and 77% mutation coverage\. At Accenture, I contributed to a micro\-frontend architecture used by 6 teams, helped reduce Lighthouse scores from 62 to 90\+, and improved frontend performance through lazy loading, code splitting, and reusable design systems\. I care deeply about writing clean, maintainable code and solving real product problems, not just shipping features\. My work spans performance optimization, accessibility, state management, API integration, and frontend architecture at scale\. I also enjoy learning beyond my core stack, which is why I’ve built side projects with Next\.js, GraphQL, Firebase, and AI\-powered workflows to keep expanding my technical depth\. I’m now looking for frontend roles where I can take ownership of difficult product challenges, collaborate with strong engineering teams, and build experiences that are both technically solid and valuable to users\. ## Location India ## AI stack antigravity claude code deepseek gemini geminicli replit ## Work experience Senior Associate Consultant at Infosys, Nov 2024 \- Present · 1 yr 11 mos, Pune District, Built a React\-based financial crime trigger management tool from scratch, replacing a manual review process across ops teams\.
