I led a team of engineers to build AutoClean, combining agents and static analysis to remove 1 million lines of dead code in two years. The system reduced stale flags and plugins from over 30% to below 7%, with 95%+ developer acceptance.With Stefan Heule, Diego Marcilio, Daniel Ramos, and Nikhil Parasaram.

NilAway is a static analysis tool that detects potential crashes caused by accessing nil values in Go. I co-led its development and rollout across 70 million lines of Go, detecting 500+ potential nil panics monthly, and built an agentic system to propose and validate fixes that helped reduce reported nil panics by 80%+ in six months in one of Uber's largest organizations.With Lazaro Clapp, Julia Turcotti, and Sonal Mahajan.

I led RPCShield's inbound and outbound dependency analysis and infrastructure, identifying 1,000+ cross-tier fail-close violations in one year. This exposed cascading-failure risks and supported more efficient CPU allocation. I also expanded RPCShield's scope to power cross-organizational initiatives such as finer-grained service criticality classification.With Milind Chabbi, Sonal Mahajan, Yufan Xu, and many others at Uber.

I built and deployed Last Diff Analyzer, eliminating manual review for 14%+ of code changes through automated checks for behavior-preserving revisions. I partnered with the testing team to integrate it into CI, saving thousands of testing hours weekly.With Adam Welc and Lazaro Clapp.
