Rockstar🎓
Top SchoolBill De Hóra is an Executive Principal Engineer and Dublin site lead at Zalando with 15 years of experience building resilient, large-scale distributed systems and leading engineering organisations. He blends hands-on backend engineering—contributions to projects like Kakfa-backed Nakadi and the widely used intercom-php client—with strategic leadership roles from principal engineer to interim VP and director-level positions. Known for pragmatic improvements to robustness and maintainability (API error handling, CI integration, serialization and feature-toggle work), he moves fluidly between code, architecture and people management. His background in AI and industrial design hints at a multidisciplinary approach to problem solving, combining systems thinking with user- and product-aware engineering.

Contributions summary:Bill primarily contributed to the back-end functionality of the `nakadi` project, a distributed event bus. Their work included adding Scala support, which involved creating Scala test and source files. Further contributions involved merging branches, and modifying Java files, alongside API definition adjustments, specifically related to data serialization for event streams and updating the content type. They also added feature toggles and integrated them into the event stream, to improve its functionality.
