Video Infra | Video Processing & InferenceAutodub + Lipsync• Worked on the A/V sync input batching library to batch and align audio/video frames before model inference• Refactored the inference daemon's threading model to resolve OOMs• Cross-host orchestration for Autodub and Lipsync inference pipeline to alleviate memory bottleneck• Ensure production readiness by adding observability signals (latency, throughput etc)Ads Measurement | Metrics EcosystemMetrics Reporting Reliability• Reduced the number of OOM (Out-of-memory) exceptions by up to 4x on 3 key endpoints powering Meta's Ads Manager by pruning unnecessary DB loadsExternal Metrics QualityLeveraging internal infrastructure to build tools and processes to ensure that metrics at Meta meet the defined metric standards. Metrics E2E Testing Framework• The sole framework that enables the end-to-end testing of the complex metric computation flow at an individual metric level.• Conceptualized and shipped a full-stack debugging tool that enables developers to visualise and inspect the event flows in a single test run. In the case of test failures, this tool allows developers to identify the point-of-failure in a matter of seconds.Operational Tooling• Developed a task chat bot on Meta's Workplace to support the triaging and resolving of HiVA (High-Value-Advertiser) reported bugs

Ads Measurement | Metrics Developer Experience• Bootstrapped a Sandbox environment which allows product team developers to quickly prototype new organic metrics (metrics updated by events that do not go through attribution)• The Sandbox reduces the time to create a new metric from 2-3 weeks down to a few hours and enhances reliability by enabling developers to perform end-to-end verification of their newly created metric locally• Owned the entire Sandbox development from setting up the infrastructure (Hack/PHP) to its integration onto a web portal that houses metric creation workflows for users• Onboarded an actual developer, who completed the development of an organic metric using the Sandbox environmentThe Sandbox is now part of the new metric development workflow across all teams at Meta.
