I build scalable backend and IoT platforms for real-time device operations and fleet management.

At Truckx, I build backend and IoT systems for a fleet of 5K+ active devices, including real-time telemetry, live tracking, remote commands, and dashcam onboarding.

I migrated production delivery from Jenkins to GitOps with ArgoCD on GCP GKE and built event-driven Node.js microservices using Pub/Sub, MySQL, and WebSockets.

I also shipped Django services that automated support workflows, cut geocoding latency by 50%, and saved $10K per month through in-house Nominatim, Mapbox fallback, and caching.

Previously, I built IoT command services at Bert Labs and REST APIs, SFTP automation, and MySQL optimizations at Visit Health.
