Go · Kafka · MQTT/Sparkplug B · Modbus · OCPP · gRPC · Postgres · Kubernetes · Prometheus. Specialist: device-to-cloud ingestion at fleet scale. Python where it earns its place.

MQTT + Sparkplug B and Modbus/SunSpec, so fleetsim can speak what industrial devices actually speak. Next up: OpenADR 3.0, and a ClickHouse vs TimescaleDB benchmark for telemetry storage.

fleetsim — a multi-protocol device fleet simulator in Go. 10,000 concurrent devices on one laptop, with fault injection: connection drops, malformed payloads, clock skew, slow responses.

Remote backend/platform roles in energy, industrial IoT and robotics fleets. Contractor (USD) or EOR. 5+ hrs CET overlap. Always up for a chat about OCPP, MQTT, or telemetry cost.
