Experience

1. Software Engineer 2

   Microsoft

   Aug 2021 — Present · Hyderabad, IN

   Designed and led a distributed data integrity and validation platform processing millions of service metadata records across microservices, introducing automated validation gates that prevented invalid state from reaching production and reduced manual audit toil by ~70%.• Solved burst-traffic and contention failures by introducing Redis-based traffic reshaping and adaptive concurrency control (95% optimistic / 5% pessimistic) after observing 50+ production retry storms, eliminating cascading update failures.• Implemented automated quality gates in CI/CD pipelines to enforce Windows developer build standards before release, and built ARM-based platform validation tooling achieving 80%+ test coverage for hardware compatibility.• Created internal developer tooling that reduced environment setup time from 60+ minutes to under 20 minutes, delivering a 3× improvement in developer onboarding and iteration speed.• Implemented a Test-in-Production (TIP) telemetry framework using C++ instrumentation hooks to improve Windows platform observability, and drove adoption through office hours and mentorship, enabling teams to detect correctness issues earlier in real production environments.• Built a UI and platform validation framework using PowerApps and RPA (Microsoft Power Automate), converting 120–130 manual QA workflows into deterministic automation and reducing UI-related bugs by ~40% prior to release.Tech Skills: Core: Distributed Systems, Event-Driven Architectures, Concurrency Control, Platform Reliability, CI/CDCloud & Infra: Azure (Service Bus, Functions, Cosmos DB), Redis, KubernetesLanguages: C++, C#, Python, BashTooling: CI/CD Pipelines, Automation Frameworks, Observability & Telemetry
