Engineering in Action
OCPP Integration for a German Charger OEM
Integrated OCPP 2.0.1 into a new DC fast charger platform. Delivered protocol conformance, backend connectivity, and field-ready firmware across multiple charger variants.
Significantly faster commissioning vs. previous generation
Embedded Test Automation for a Healthcare Device Manufacturer
Built an automated unit testing pipeline for safety-critical MCU firmware. Replaced manual verification with CI-gated tests covering CAN bus, temperature compensation, and EEPROM integrity.
~85% reduction in manual test effort (estimated)
Communication Protocol Fix for an Industrial Systems Integrator
Diagnosed and resolved Modbus RTU timing issues causing intermittent data loss in a multi-device industrial network. Implemented deterministic task scheduling and time synchronisation.
Zero data loss after deployment
