Engineering Lead \| Scalable Frontend Architect \| Leading high\-performance teams

## About

I am a Senior Technical Lead with 10\+ years of experience building scalable frontend platforms, SDKs, and hybrid apps across FinTech, Healthcare, and Public Sector domains\. At Paytm, I led the architecture of a central Frontend SDK powering \~80% of app pages, improving Core Web Vitals, integrating OM\-SDK for ads tracking, and cutting regression testing time from 1 week to 3 hours through automation\. I thrive at the intersection of technical leadership and hands\-on coding, mentoring teams while solving high\-scale performance challenges\. Previously, I delivered impactful solutions at Optum, Deloitte, Nagarro, and TCS, including PWAs with Next\.js, scalable React Native applications with offline\-first design, and Salesforce LWC systems\. My career highlights include: Performance\-driven engineering → PWAs, lazy\-loading, workers, offline\-first systems\. Platform building → SDKs, atomic architecture, code\-generation frameworks\. Leadership & collaboration → Led teams of 2–4 engineers, cross\-functional delivery with PMs, QA, and stakeholders\. I’m passionate about building reliable, high\-performance frontend systems that directly drive business growth and user engagement\. Beyond product delivery, I built Z\-One, a VS Code extension integrated with MCP tools to streamline developer workflows — a project that gained strong adoption within Paytm and showcased my ability to innovate developer productivity platforms\.
