Software Engineer at Meta

June 1, 2022 - Present

Built an internal AI-driven document intelligence platform to parse, classify, and extract structured data from unstructured documents (primarily financial PDFs). Architected Python-based backend orchestration handling 100K+ documents per day, coordinating ingestion, asynchronous processing, retries, and delivery to downstream compliance and analytics systems. Implemented a dynamic AI model routing and fallback framework (Llama, Gemini, OpenAI, and Anthropic), selecting models based on confidence scores, document complexity, latency SLAs, and cost thresholds. Developed high-throughput C++ components for text extraction and layout analysis; deployed containerized microservices with distributed queues, centralized logging, and metrics-based monitoring, achieving 99.9%+ pipeline availability.

Senior Software Engineer at LinkedIn

September 1, 2018 - June 1, 2022

Built scalable backend services for Kafka Cruise Control to automate cluster health monitoring, partition rebalancing, and self-healing across LinkedIn's trillion-message-per-day streaming infrastructure. Implemented REST APIs for triggering rebalances and retrieving cluster health, extended pluggable optimization goals for rack awareness, replica distribution, and capacity constraints. Developed metrics ingestion and analysis pipelines to drive rebalance decisions and capacity planning, improving efficiency and reducing manual intervention by 60%+. Collaborated with infra and SRE teams to safely deploy changes in multi-tenant clusters.

Member of Technical Staff III at VMware

July 1, 2017 - September 1, 2018

Contributed high-performance C++ components for NSX-T Data Center's distributed data plane and control plane, enabling scalable software-defined networking across multi-cloud environments. Improved stability by addressing memory usage and threading efficiency, reduced packet loss in stress scenarios, and supported multi-tenant network isolation and security policy enforcement. Participated in performance benchmarking, scale testing, and production hardening; collaborated across teams to debug complex distributed systems issues.

Software Engineer at Intuit

January 1, 2015 - July 1, 2017

Developed real-time invoice and payment processing microservice for QuickBooks Online using Java/Spring Boot, handling 3M+ monthly transactions. Implemented backend business logic integrating with billing, ledger, and tax calculation systems; designed relational data models and optimized PostgreSQL queries (approx. 25% performance improvement). Built Redis caching, asynchronous processing with ActiveMQ, Swagger API documentation, and CI/CD pipelines; contributed to staging/deployments and improved peak-load latency by 30-40%.

Software Engineer at Viralheat

September 1, 2013 - January 1, 2015
