Anton Tsitou is a seasoned technology leader and co-founder currently serving as CTO of Spiral Scout with over a decade of hands-on experience building high-performance backend systems and developer tools. He combines deep expertise in PHP and Go—authoring influential projects like RoadRunner, Spiral, Cycle ORM and the Temporal PHP SDK—with practical product delivery for US-based clients from his San Francisco base. Anton’s background in advanced mathematics drives a pragmatic approach to system design, testing and observability, evidenced by his contributions to core framework internals, IPC/RPC bridges, and robust unit-test improvements. Besides leading engineering teams, he contributes technical documentation and SDK guides that lower the barrier for other PHP developers adopting modern async and orchestration patterns. Notably, he bridges embedded and server-side concerns, reflecting a rare full-stack systems fluency that spans from low-level IPC to cloud-scale process management.
