Over the past decade, I have focused on engineering reliable developer platforms, API contracts, and distributed backend infrastructure. At Walmart Global Tech, I orchestrate GraphQL platforms that streamline how services integrate and communicate across complex domain boundaries.
Prior to Walmart, I led frontend performance initiatives at Quikr, driving Progressive Web App architecture that reduced initial load times from 7 seconds to 2 seconds, cutting bounce rates by 25% for millions of users across India.
Outside enterprise platform systems, I experiment with homelab infrastructure, self-hosted clusters on Raspberry Pi, open-source utilities in Rust and TypeScript, and writing technical explorations on system architecture.

Operating Principles
Platform Engineering Philosophy
Paved Roads Over Mandates
The safest path must be the easiest path. Tooling, scaffolding, and automated validation should guide engineers into the pit of success without cognitive friction.
APIs & Schemas Are Forever
Public schemas outlive their implementations. Prioritize backward compatibility, contract-driven design, and evolutionary changes over disruptive breaking rewrites.
Leverage Is The Primary Metric
A platform team exists to multiply the velocity of product teams. Success is measured not merely by service uptime, but by how quickly and safely other teams can ship.
Boring Foundations, Expressive Edges
Rely on proven, predictable primitives for core routing and data pipelines. Invest creativity into developer ergonomics, typed client codegen, and instant feedback loops.
