About Me

Josiah James Fowler

I build scalable web and mobile products that prioritize accessibility, reliability, and real user impact. Based in Boston, MA, I specialize in end-to-end full-stack development with TypeScript, React, React Native, Node.js, PostgreSQL, and GraphQL.

Key Achievements:
• Delivered 25+ full-stack features and launched a mobile app with full web parity, driving a 3x increase in user adoption
• Cut deployment time by 60% and reduced maintenance overhead by 40% by migrating from microservices to a Convex-powered monolith
• Led engineering processes that increased team velocity by 35% and reduced spam 70% in 30 days

I thrive in collaborative environments, working directly with product owners to shape roadmaps and creating systems that drive measurable outcomes for users and business.
