Summary
👤
Senior🎓
Top SchoolBrian Fitzsimmons is a Lead Software Engineer in Seattle with nine years of hands-on experience building full-stack web products, mobile apps, and ML pipelines. He’s shipped fast, cost-efficient production systems—from a purchasable academic recruitment platform built in under three months with sub-$100/month operating costs to Sporcle features that scaled to millions of daily gameplays. Comfortable across TypeScript/React/Next.js, PostgreSQL, AWS/GCP, Docker, and data tooling, he blends product-minded engineering with evidence-based decisions (including a 98% accurate time-series forecasting model). A self-taught developer and former food-truck hopeful, he pairs entrepreneurial grit with practical delivery in startup settings. Outside code he’s an avid pianist, hiker, and dancer, and plans to add game development to his technical repertoire.
