What I'm looking for

I'm open to remote opportunities where I can own end-to-end delivery of scalable web products, turn ambiguous requirements into practical solutions, and improve reliability, automation, testing, and developer productivity.

I've built and scaled production web platforms at Moonshot Partners, CareerBuilder, Bigwave, and Slice Group using Ruby on Rails, React, EmberJS, TypeScript, Node.js, and AWS. At Moonshot Partners, I helped scale a multi-tenant Rails monolith to 1,000+ concurrent tenants while keeping average response times below 200ms.

I own features from ambiguous requirements through delivery, with a focus on automation, reliability, and code quality. I've reduced survey-processing latency by about 80%, cut deployment time by 30%, improved test coverage by 30%, and modernized infrastructure with Terraform.
