What I'm looking for

I seek backend-focused roles where I can lead Elixir microservice work, apply TDD, mentor engineers, improve reliability, and reduce technical debt.

I am a senior backend software engineer with nearly two decades of experience building and maintaining web applications, microservices, and integrations. I prioritize TDD, clean code, reducing technical debt, and shipping reliable production features.

For the past 4–5 years I have focused on Elixir and have led migrations from Ruby on Rails monoliths to Elixir microservices, worked with GraphQL, REST, Kafka, and optimized CSV streaming from S3 using Oban Pro Batch.

I have designed and implemented API integrations (DocuSign, Greenhouse), improved operational health through library updates and Kubernetes scaling, and led customer-facing automation to reduce response and resolution times.

I am a collaborative mentor who documents processes, participates in architecture and patterns working groups, manages and supports junior engineers, and evangelizes best practices to improve team delivery and product quality.
