I’ve been building software for nearly two decades, from Ruby to iOS and now Elixir. I’m an experiment-driven builder who loves shipping practical solutions to real problems. Over the past six years, I’ve focused on entrepreneurship, and today I’m the founder and CTO of a vehicle meta-search startup.

Rebuilding Workflow Orchestration in Elixir: The Story of Gust
A case study on building Gust, a durable workflow orchestration system in Elixir, after getting frustrated with Python/Airflow. I’ll break down what “orchestration” really means, what Airflow does well (and where it gets heavy), then walk through Gust’s core pieces: task, scheduling, retries, logs/observability, and secrets. Finally, I’ll show how OTP supervision and lightweight processes enabled a simpler, more reliable engine with major efficiency and performance gains.
Key Takeaways:
- Know what an orchestration system is, what problems it solves, what Airflow and Gust are, and how they differ from a background job library.
Target Audience:
- Platform / ML engineers, as well as tech managers.
