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.
