About

Senior full-stack engineer with 13 years of experience taking production systems from concept to scale. Currently leading platform initiatives at iFIT: Owning real-time data pipelines, cross-domain communication infrastructure, and high-impact partner integrations across Node.js/TypeScript, Kafka, MongoDB, and AWS. Recent work includes: * Owning a biometric telemetry ingestion pipeline (NestJS, Kafka, MongoDB, GraphQL) handling tens of millions of samples per month * Engineering lead on an MQTT bridge providing real-time, two-way messaging between client systems and platform services * Leading the engineering integration with Strava for a go-to-market partnership reaching 150M+ users I'm also actively shaping how my team works with modern AI tooling with agentic coding workflows, custom Claude Code skills, and AI-assisted code reviews to multiply team velocity without sacrificing engineering rigor. Prior to platform work, I spent 8 years in mobile development at iFIT, with earlier stops as an engineering lead at a web agency (Eyeseethree) and a software engineer at a Los Angeles ticketing company (Flavorus).
