I'm a senior software engineer and technical leader with over 30 years of experience building high-performance systems for startups, media companies, and enterprise platforms. I specialize in backend architecture, functional programming, and system design, with deep experience in Go, Elixir, and Python. I've led engineering teams, shipped production software across a range of stacks (Rails, Django, Flask, FastAPI, Phoenix, gRPC, GraphQL, Kubernetes), and delivered mission-critical features in areas like streaming media, mobile infrastructure, and AI/ML pipelines. Beyond hands-on coding, I’ve run Elixir training workshops across the US and Europe, launched internship programs to support underrepresented developers, and trained in both product leadership (SVPG) and management (AIM Utah LDI). I bring a "simple and demonstrably correct" approach to every project—prioritizing clarity, testability, and long-term maintainability. I'm available for remote freelance and contract opportunities—especially those that value thoughtful architecture, fast iteration, and strong collaboration between product and engineering.More...
