What I do

Three layers of the same job: keep the picture up.

From the player on the glass to the alert that fires before anyone notices, and the tools built to prove it works.

01 / Broadcasting · Video

Streaming that stays on air

Video players and playback at scale: delivery, DRM, latency and the long tail of devices.

02 / Reliability · SRE

Systems that tell the truth

Observability, alerting and load testing. Signal over noise, so failures surface before users feel them.

03 / Build

Products, shipped

From idea to deployed: tools, services and side projects across 50+ repositories.
