About Jay Okawachi

Senior full-stack software engineer with a backend and platform focus, working on scalable, data-intensive systems. I’ve spent much of my career modernizing and stabilizing complex, legacy platforms, which sharpened my ability to reason about system boundaries, failure modes, and long-term maintainability.I specialize in backend and data platform development using Elixir, applying functional programming, OTP, and distributed systems patterns to build reliable ingestion, curation, and application layers. I focus on pragmatic architecture, iterative delivery, and strong testing practices balancing near-term execution with long-term scalability.I regularly contribute to architectural direction, influence engineering standards, and mentor teammates, while remaining hands-on with design and implementation. Open to connecting with engineers working on backend systems, data platforms, or functional programming.
