Serene

The first entry in the ledger. Serene tackled student burnout with binaural beats synchronized to the listener's actual heartbeat — calm engineered from biometrics rather than a generic meditation track.

It won first place at the Smart India Hackathon 2022, against a field of 1.5 million participants. More durably, it taught me the pattern every later project follows: find the mechanism (entrainment), instrument the human (heart rate), close the loop.
