PROFILE

Daniël Koek

Developed end-to-end hardware integration and documentation for the GDEY029T94 e-paper display in the esphome/esphome and esphome/esphome-docs repositories, expanding ESPHome’s device compatibility. This work included model registration, initialization, rendering, and configuration dump in C++ firmware, alongside updates to reStructuredText documentation for improved user onboarding and clarity. Later, implemented Workload Identity authentication support in the MSAL integration for microsoft/Agents-for-net, enabling federated token-based authentication for AKS and adding validation for key configuration parameters. Demonstrated expertise in embedded systems, device drivers, authentication, and cloud security, with a focus on maintainable, cross-repository solutions using C++, C#, and Python.
