April 2024 to now: working on capacity infrastructure at Meta's vast scale. Make services across Meta run efficiently and empower the AI growth. **I am hiring!**Nov 2022 to April 2024: AI infrastructure. Empower thousands of ML engineers to move fast and reliably with large-scale ML platform. Built and led team of ~50, Bellevue, Bay Area and London.2020 to Oct 2022: built the next-gen CI/CD platform for FB: distributed workflow systems, Machine Learning based test selection, developer-facing UX. 2018 to 2019: buck, buck2, and Facebook's distributed build infra

I run the Pipelines team. We own CI/CD for Amazon, powering thousands of services to release code continuously, safely, and rapidly. Pipelines, the in-house CI/CD platform, is used (and loved) by almost every Amazon developer, orchestrating millions of source/build/deployment/test workflows every day. * Grew the team size from 3 to 16, including another dev manager and multiple senior IC/tech leads.* Led the efforts to scale the system to meet rapidly growing demands and use cases. Transformed the product from running on a legacy monolithic backend to a modern microservice architecture on AWS.* Led the innovation of new CD solutions for large-scale deployment workflows.* Helped shape the CI/CD roadmap at Amazon and advocated for engineering/deployment best practices.

I designed and built test infra for ads management and serving systems. The tools and services I built were initially used by Ads org and later adopted by hundreds of teams in the company for fuzzing, failure injection testing, automatic test data generation, and integration test coverage analysis. Incubated operational analysis tools used by ads ops teams. Bootstrapped a team to keep developing the growing toolset.

I built test execution infrastructure, lab management and provisioning tools, model-based test automation tools for distributed VM / enterprise DataCenter management systems that orchestrated hundreds of physical hosts and thousands of virtual machines.

Built browser plugins to render 3D virtual rooms and a rich web application to find furnitures and decorate the virtual rooms with them.

I extended and customized game engines to build 3D modeling and industrial simulation software.
