At Transket, I designed and shipped an append-only, immutable double-entry credit ledger with idempotent writes, making the ledger sum the source of truth for balances. I also integrated two payment gateways behind one adapter interface and rebuilt consent as a first-class gate on inbound messages.
At Trigeminal AI, I built backend pipelines for large-scale medical imaging and automated ingestion with Celery and Watchdog, cutting manual operations by 50%. I optimize for correctness over cleverness, measure claims before acting on them, and design for idempotency and safe migrations.
