about
Hey, I'm Sanjae. I'm a software engineer at Bloomberg, and I build backend systems for a living. Outside of work, I love travelling, learning new skills and just pushing past my comfort zone.
I've been lucky with the teams I've landed on. At Rippling, I built backend services for profile changes across HR and payroll for 20,000+ companies. At Activision, I worked on the Call of Duty store (that one, 100M+ players). At Nokia, I built internal data tooling.

6 entriesBouncerv0.1 · cliactive
A context compiler for AI coding agents: LLVM, but for context windows. It sits between the agent and the model, converts repository state, history, and tool output into a compact intermediate representation, and emits a leaner prompt tuned to each target model. First shipped piece is a recording proxy that measures where an agent's tokens actually go.
flight-trackerv1.0 · webshipped
A $0/month cheap-flight tracker for one route (NYC ↔ Toronto). An hourly poller queries Google Flights, stores fare snapshots in Postgres, and emails a booking deep-link the moment a round trip gets cheap; a React dashboard shows which weekends are cheapest with per-option price history. Runs entirely on free tiers.
s.suitedev toolingactive
