Technical owner for a mission-critical rental + inventory platform with Lightspeed R-Series integration supporting real-time, location-based availability and operational workflows. Implemented idempotent workflows and correctness guards to keep rental state consistent with POS-side actions.
- Designed near-real-time ingestion and reconciliation (streaming sync, backfills, consistency checks) with a 2-minute worst-case propagation SLA.
- Built a multi-tenant worker system with strict timeouts, retries/backoff, and an ops dashboard to harden reliability under third-party failures.
- Authored a typed R-Series client + distributed Redis token-bucket limiter to stabilize concurrency and sustain 7+ months incident-free operation.
