What I'm looking for

I'm looking to build scalable backend systems, AI developer tools, and production web platforms where I can own architecture, improve performance, and lead engineering teams.

At Refactyl, I’m building a developer tool that automatically migrates and refactors production codebases with clean, reviewable diffs. I engineered a deterministic Express-to-Fastify migration engine benchmarked at 3.1x throughput, shipping files only when real compilers accept them.

I own engineering for Mighty Champions’ preventive mental-health education programs, shipping 15+ production websites and an end-to-end admissions platform. At Voxa, I led architecture and technical direction for an AI-powered multilingual speaking coach while managing eight engineering interns and establishing code review, CI/CD, and repeatable releases.

Across independent work, I’ve architected backend systems for 10k+ concurrent users, sub-100ms real-time latency, and 2M+ events per day. I also build AI-enabled platforms such as LUTBuilder.ai, combining real-time workflows, AWS Lambda pipelines, and subscription billing.

Refactyl

Dec 2025 - Present (8 months)

Founded Refactyl, a developer tool that automatically migrates and refactors production codebases to modern frameworks with clean, reviewable diffs. Engineered a deterministic migration engine (Express to Fastify) benchmarked at 3.1x throughput (12k to 38.9k req/s), compiler-gated (tsc, @vue/compiler-sfc) so files ship only if the real compiler accepts them.
