2026 - present: Senior IC on the (Ads & Core) Product Infra leadership team.

2022-2025: Senior IC/Architect on the Core Foundations org (basically Core Product Infra plus Client Foundations) leadership team, directly supporting the full stack Video/Image Platform (transcoding, delivery and playback on client platforms), and Performance Engineering (latency, efficiency) from end to end; also some cross-platform/org initiatives.

2020-2022 Client Platform/Infra initiative: - co-founded Client networking, upgraded Pinterest to http/3; built a logging/observability end-to-end pipeline for mobile client from the ground up; some iOS build/bazel work; a few optimization/reliability work.

One of the first few mobile platform engineers at Uber:

• Realtime api rewrite / client migrations.

• Founding member of App Performance and iOS lead (startup, models caching, UI responsiveness, etc)

• Founding member of Mobile Networking (Optimization/PushStreaming/HTTP3/gRPC, HelloHttp)

• Went though some app rewrites; platforms libraries optimizations, etc.

• C++ dev on mobile platforms

• First iOS engineer at the company(from a startup to a public listed company) since 2008, later as an EM led their iOS/WindowsMobile eng teams there.

I also learned Map & Navigation technology there.
