👤
Senior🎓
Top SchoolJames Crowson is a hands-on Head of Engineering with 14+ years building scalable web and mobile products, currently leading an AI-powered B2B SaaS platform from a one-person codebase to a 16-person engineering organisation. He combines day-to-day delivery—shipping production React/Next.js/TypeScript code and shaping backend Node.js architecture—with strategic responsibilities including hiring, roadmap prioritisation, and technical due diligence for seven-figure Series A/B raises. Over the past three years he’s focused on LLM-driven features and agentic workflows that embed GPT- and Claude-class models into customer-facing apps and developer platforms. A former solo founder of Upmostly, he grew a React/JavaScript tutorial site to 3M annual visitors, honing SEO, mentoring, and content-driven growth skills that complement his product-minded engineering leadership. Based in London, he’s equally comfortable in code reviews and board-level technical reporting, and has a track record of delivering high-traffic, reliable systems used by major retailers.
