What I'm looking for

I'm looking to build backend services, cloud infrastructure, and developer tooling where I can lead delivery, solve production problems, and mentor engineers.

I'm currently building backend storage features for Zitadel, including Golang/gRPC services, PL/pgSQL database functions, and a migration from CQRS to a PostgreSQL relational model.

At Spenmo, I led a team delivering a Go microservice for card and team spending limits, migrated data from DynamoDB to MySQL, and reduced card preauthorisation performance from roughly 1.2 seconds to under 500 milliseconds by simplifying PHP code into Golang on AWS Lambda. I've also built internal Go CLI tools for Skyflow, Airflow DAGs and Go services for GoodRx, and production infrastructure on GCP for The New Fork.

Across roles at Gentrack, Amadeus, and N.able-it, I've delivered Java, C++, Python, Linux, REST, and SQL solutions for utilities, airline migration, and backup systems. I enjoy investigating production issues, mentoring junior engineers, and contributing improvements to open-source Go editor tooling.
