Top School

Joël Gähwiler is a Swiss CEO and managing director with 14 years of hands-on software engineering and product leadership experience, currently leading Networked Artifacts and sternenbauer GmbH from Zurich. Trained as an interaction designer (MA/BA, ZHdK), he combines design sensibility with deep backend engineering—contributing to performance-critical Go projects such as the RocksDB-inspired Pebble and JSON:API implementations where he improved resource management and reduced allocations. His open-source work spans embedded IoT (Arduino MQTT client) to core database internals, reflecting a rare blend of low-level systems thinking and user-focused product design. Comfortable shipping both firmware-level clients and server-side infrastructure, he emphasizes robustness (proper io.Closer patterns, memory safety) and pragmatic performance. Colleagues would note his dual focus on craftsmanship and business outcomes: he moves between code, architecture and company strategy with ease.
