Experience
Software Engineer
Microsoft · NoidaPython, TypeScript, Docker, Azure, React, Playwright
- Engineer and evaluate AI-powered experiences across multimodal models and agentic workflows for the Excel Copilot team.
- Owned the end-to-end Responsible AI (RAI) evaluation pipeline gating model releases; optimized execution latency by 50% through asynchronous worker pools, intelligent request batching, and custom retry algorithms.
- Onboarded next-generation multimodal AI agents into the core evaluation platform, designing pluggable backend adapters, isolated container sandboxes (Docker), and concurrent distributed cloud runtimes.
- Designed and implemented a parallelized automation framework for synthetic data generation and evaluation; boosted throughput by 5x and generated 70,000+ trajectories across 20,000+ enterprise workbooks.
- Served as on-call engineer driving infrastructure reliability across evaluation pipelines—triaging partner team issues, resolving live-site instabilities, and handling incident response to maintain >95% reliability.
- Integrated comprehensive telemetry pipelines and KQL aggregations processing millions of daily events, establishing single-pane system health dashboards and automated triage.
System Software Designer
Advanced Micro Devices (AMD) · BangaloreC/C++, Java (OpenJDK), Linux perf, Python, Django, React, SQLite, Docker
- Engineered an OpenJDK performance monitoring and telemetry platform (Django, React, SQLite) to track nightly SPECjbb runs, enabling early detection and isolation of performance regressions.
- Automated systems to benchmark and tune Java nightly using machine learning models, achieving a 30% reduction in manual effort and improved parameter accuracy.
- Applied advanced Java tuning techniques and profiled CPU/memory bottlenecks with Linux perf, yielding a 2% throughput increase on SPECjbb benchmarks across High Performance Computing (HPC) servers.
- Refactored and containerized legacy benchmarking workflows with Docker for cross-platform execution, driving a 90% reduction in deployment and environment errors.
- Awarded the Spotlight Award for exceptional contributions to automation, tuning, and nightly benchmark visualization.
