@matthewsaunders
Senior software engineer building scalable Elixir-aligned backend APIs and microservices.
What I'm looking for
I’m a Senior Software Engineer with 10+ years of experience designing and delivering distributed backend services, microservices architectures, and high-traffic systems. I focus on performance, observability, and maintainability, with strong alignment to Elixir-style patterns like OTP, Phoenix-style APIs, Ecto-backed data access, and async processing.
Across Meta, Twilio, and Aha!, I’ve built and scaled backend services and orchestration pipelines, improved production reliability with structured logging/metrics/tracing/alerting, and mentored teams through code reviews and design leadership. I also integrate AI-driven capabilities—automation, recommendation systems, and LLM-powered experiences—while partnering cross-functionally to deliver end-to-end solutions from architecture through deployment and iteration.
