Airgo XP — Ergonomics Platform
Co-led Airgo XP, a production ergonomics platform for logistics environments. I built the Kotlin session-processing pipeline that turns 500 Hz sensor streams into worker sessions, ergonomic metrics, and analytics-ready records — a write-heavy, timing-sensitive path that had to stay reliable on resource-constrained field devices.
The most useful thing I did on it was designing a k6 load test simulating five teams, 100 workers, 15 days, ~1.4M sensor records. The results surfaced the real bottlenecks and drove roughly a 70% throughput improvement in the workflow. I also integrated custom ML inference into the pipeline for real-time posture / activity recognition (≥80% accuracy) and validated the whole thing through 600+ hours of user testing.
Companion — BLE Signal Processing
Built Kotlin/BLE processing components handling signals from 600+ Bluetooth beacons concurrently in warehouse environments. Pushed for clean architecture and disciplined testing — the component reached 90%+ test coverage, which cut regression risk on releases meaningfully. Also mentored junior developers and helped drive technical planning and release prep.
