// about me

Engineer who ships.
Enjoy building
B2B SaaS.

I'm a senior software engineer with experience building backend systems for B2B SaaS companies. Most of my production work has been in Ruby on Rails with focus work on tenant provisioning, payments with Stripe, search with Elasticsearch, third-party integrations, and the background-job infrastructure that holds it together.

I care about clean architecture, solid test coverage, and code that the next engineer can actually read.

I've mentored junior engineers, led code reviews, and written documentation that outlasts the sprint it was written in.
