Where I've worked

From PLCs in a building's control room to Kubernetes in the cloud.

  1. Singapore

    Building IoT platform
    • Own the platform's Cloud Build CI/CD pipeline; 169 of my PRs merged so far.
    • Migrated it from one VM to GKE microservices with Terraform.
    • Wrote the safety pattern for remote control of air-conditioning and built its guards into the control bridge: deliberate arming, manual override, rate caps and readback from the plant.
    • Changed the live cluster in reversible steps: a password on the cache in two steps, a second replica for the command transport, and a register of single points of failure with measured or estimated recovery times.
    • Ran on-site control tests at a customer site, rehearsed first on a Modbus bench simulator I built.
    • GKE
    • Terraform
    • Cloud Build
    • Kafka
    • MQTT
    • Modbus
    • Grafana
    AI agent platform
    • Deployed and operated the agent and RAG services on Cloud Run, with models on Vertex AI and OpenRouter.
    • Set up per-environment CI/CD, IAM, Secret Manager and shared-VPC networking for dev, staging and production.
    • Benchmarked the stack: load and latency tests of the agent API, token cost per request, and models compared on latency and cost.
    • Built a demo building for the agents to query: 50 storeys, 2,014 BMS devices.
    • Cloud Run
    • Vertex AI
    • Cloud Build
    • Secret Manager
    • IAM

    Also

    • For a customer, outside both platforms: a read-only Modbus reader for 718 energy-meter channels, tested at full scale against a simulator.
