What I'm looking for

I'm looking to build pragmatic, high-quality software with teams that value learning, collaboration, scalable architecture, and delivering features quickly without sacrificing code quality.

I've led development for KiwiSkips, RevZilla, and Dycoders, building customer platforms, scalable services, and production deployment pipelines across Elixir, Ruby on Rails, Node.js, React, and Phoenix.

At RevZilla, I led the transition from C# and Ruby microservices to Elixir, improving response times, resource utilization, resilience, and fault tolerance through OTP and supervisor patterns. At KiwiSkips, I delivered a mobile-friendly customer platform with real-time bin-emptying tracking and feedback mechanisms.

I've also led teams on Vendorful and Spideraf, migrated a React frontend to Phoenix LiveView to address performance issues, and built systems for food supply chains, HR, recruitment, IoT, e-commerce, and digital media fraud detection.
