• ● Scaled a multi-service, asynchronous governance platform with 200–500K MAU, handling
• peak compliance-window traffic and processing millions of records with 99.99% uptime, directly
• funnelling multi million dollar revenue-critical seller operations at Microsoft.
• ● Designed and implemented APIs in a distributed Azure environment, handling 100K+ RPS, owning production readiness using blue-green deployments, idempotency, rate limiting, DLQ handling, and operational monitoring.
• ● Spearheaded development of a dynamic Business Rules Engine leveraging NodeJS and .Net, supporting 100+ workflows, enabling complex approval and conflict resolutions at scale, replacing a legacy system and adopted by 10+ internal teams.
• ● Led performance optimization across multiple services, introducing multi-layer caching, reducing P95 latency from 3–5s to <1s and eliminating production timeouts.
• ● Improved SQL Server performance, reducing query latency by 30% on critical apis and eliminated timeout alerts in production.
• ● Improved reliability of legacy systems by increasing unit and integration test coverage, reducing production regressions.
• ● Built end-to-end observability (tracing, telemetry, dashboards) across services, improving incident detection and MTTR by 30%, reducing Sev-1/Sev-2 azure incidents.
• ● Led zero-downtime migrations across 3 production services, delivering infrastructure, application, and schema upgrades for revenue- and compliance-critical workloads.
• ● Refactored a +100K LOC legacy monolith in .Net and nodeJS, eliminating 20K+ lines of duplicate code, reducing blast radius, faster, safer deployments.
• ● Migrated 20+ REST APIs to GraphQL for core Microsoft offerings, enabling read-heavy access (100K+
• req/day) and solving N+1 and schema evolution challenges.
• ● Mentored 2+ engineers through design reviews and on-call guidance, establishing team-wide standards for backend design patterns, API versioning, and test coverage, improving code quality and long-term maintainability.

• Built products and services for Microsoft’s Partner and Seller Ecosystem.
• Led the development of a configurable Widget generation toolkit using reactJS and typescript, which accelerated boilerplate react code generation for widget earlier developed from scratch, reduced time from 3-4hours to few minutes. The eventual adoption also led to “time to deliver” improvements from a week to 3 days commanding 50% improved efficiency.
• Enforced and led the design system, code ethics, coding standard, accessibility compliance and code coverage of all the widgets and components being developed by the team, ensuring high quality delivery in UI with high code coverage thereby increasing production confidence and reduced prod regressions.
• Improved the newly built complex widget by integrating it with detailed observability using consistent correlation ids which allowed on-call engineer to trace and mitigate any ui related or backend data staleness related issues within 15 mins, down from 2 hours.
• Single handedly led the development of a complex widget which allowed users to view seller account hierarchies and make changes to it via drag n drop features, powered by graphQL as an api layer and MSSQL as data layer. The backend system is further enriched by ETL pipeline using azure databricks to pull data from crucial upstreams (azure data lakes), transform and rollup information using scripts written in scala/python and finally push it to MSSQL as a destination.
• Joined as a sde 1, responsible for integrating GraphQL apis with react UI layer for seamless, multi device payload optimisations. Further improved the user experience by optimising client side performance by using techniques like “application caching”, “indexed DB” for optimistic UI updates. This improved the overall perceived latency from ~2 seconds to under 1 second and directly led to improved user retention by 20%
