Engineering software that scales.

I'm a Senior Software Engineer with deep expertise in Ruby on Rails, Elixir/Phoenix, and modern web architecture. I thrive on solving complex problems — from designing GraphQL APIs and microservice architectures to optimizing performance with caching layers and search engines.

Currently at Local Labs, where I build and maintain the platform powering community news delivery across thousands of US communities. I bring a pragmatic, product-oriented approach to backend engineering — writing code that is maintainable, performant, and built to last.
