About

I'm a frontend engineer with over a decade spent close to the product — building the interfaces, platforms, and infrastructure that let large teams ship quickly and let users experience something that simply works. Today I work at Dream Sports, building high-scale gameplay, monetization, and developer-platform systems across Dream11 and its sister products.

I care most about the parts of engineering that never show up in a screenshot: the architecture that keeps a codebase fast as it grows, the contracts between frontend and backend, and the developer experience that turns a ten-person feature into a hundred-person platform. Good systems make the right thing the easy thing.

Over the years I've led frontend architecture for products handling 50,000+ requests per minute, shipped revenue-critical payment systems, and built an internal platform now used across an entire company. I optimize for outcomes — reliability, performance, and the speed at which a good idea reaches production.

Engineering Highlights

Production systems and internal platforms — framed as problem, approach, and outcome.

01 Platform Engineering

Dreamplay — an internal PaaS the whole company runs on

Problem Every internal tool and customer-facing app meant bespoke infrastructure work and waiting on platform teams. Shipping was slow, and ownership was fragmented.
Approach Built from scratch — a self-service Platform-as-a-Service for Node.js, Python, Docker, and static apps. Custom reverse-proxy and WebSocket routing layer with secure identity propagation, cross-domain auth, multi-tenant hosting, deployment orchestration, real-time build-log streaming, RBAC, PostgreSQL DBaaS provisioning, and AI-assisted query tooling.
Impact Adopted company-wide. Eliminated the platform-team bottleneck — any engineer can go from idea to production in minutes, with full observability, auth, and a managed database included.

02 Architecture · Scale

Manager Mode — a reusable foundation for mobile gameplay at scale

Problem A brand-new gameplay mode for millions of Dream11 users needed a frontend foundation that multiple teams could build on simultaneously — without diverging into one-off implementations.
Approach Owned frontend architecture, API contracts, and GraphQL integration patterns from zero. Built reusable platform foundations and led end-to-end delivery across Home, Team History, Draft, League management, leaderboards, and contest workflows on React Native and Expo.
Impact A coherent, reusable gameplay platform serving millions of Dream11 users — shipped end-to-end and adopted across every gameplay touchpoint.

03 Mobile · Creator Economy

Creator Economy — monetization, audio, and premium native experiences

Problem A creator-focused product needed end-to-end monetization, premium content discovery, and native audio experiences — for both creators and subscribers, on iOS and Android simultaneously.
Approach Owned the full creator-economy surface: in-app subscription flows with server-side validation and entitlement management; premium content discovery UIs; a custom cross-platform audio framework; and deep-linking via iOS Universal Links — all on React Native.
Impact A complete creator platform live on iOS and Android — with revenue-safe subscriptions, native-quality audio experiences, and measurable subscriber growth.

04 Performance · Enterprise SaaS

Freshworks — frontend architecture and performance at enterprise scale

Problem Operational workflows depended heavily on manual intervention, and high-traffic pages were slow enough to noticeably hurt daily usage across a global enterprise user base.
Approach Built automation processing 50,000+ requests per minute; led a cross-team performance program targeting the slowest, highest-traffic surfaces; and drove frontend architecture initiatives improving maintainability and developer productivity across the org.
Impact Over 50% reduction in page load times, sharp drop in manual operational overhead — recognized internally as Best Engineer (Q1 2021 and Q2 2022).
