What I'm looking for

I’m looking to lead frontend and platform/SDK engineering on scalable Micro Frontends and accessibility-first SaaS products, and to grow into agent infrastructure—building production-grade agents using MCP and the Claude Agent SDK.

I’m a Lead Frontend Engineer with 9+ years architecting scalable, high-performance SaaS web applications using React, TypeScript, and modern JavaScript. I bring deep Micro Frontends architecture and production SDK development experience, including real-time VoIP over SIP and WebRTC.

At Samsung SDS, I defined and enforced frontend best practices and led performance optimization using React Profiler and Webpack Bundle Analyzer—improving application performance by 30% and significantly lifting Core Web Vitals. I also advanced WCAG accessibility compliance, optimized CI/CD pipelines, and improved deployment reliability with observability via New Relic.

Most recently at CleverTap, I owned and evolved the core Web SDK for a high-scale SaaS customer engagement platform—shipping independently deployable modules via Micro Frontends to enable parallel team delivery. I built the SignedCall Web SDK from scratch (VoIP over SIP/WebRTC), improving user engagement by 20%, and increased SDK reliability with a TDD-based automated testing strategy (Jest, React Testing Library, Cypress), while mentoring teams to reduce defects by 40%.
