About James Crowson

As an accomplished Head of Engineering and seasoned software engineer, I have a robust track record of successfully delivering projects, building B2B and B2C products, and leading and expanding high-performance engineering teams.Career highlights:With over 14 years of experience in the tech industry, I've had the opportunity to work with a range of businesses, from small startups to large enterprises. My journey has seen me take on various roles, including engineering manager, tech lead, and software engineer, primarily within the web ecosystem, and using JavaScript and TypeScript (React, Next.js, Node, and RedwoodJS).For the past six years, I've been leading engineering teams, most recently as Head of Engineering, where I manage a talented group of 16 engineers, designers, and QA professionals. While my leadership skills are well-honed, I'm always ready to get hands-on when needed, bringing excellent software engineering and architectural skills.One of the most exciting chapters of my career has been experiencing the full "start-up journey". As the first engineering hire at a startup back in 2020, I built the early engineering team to develop an AI-powered B2B SaaS platform. We quickly scaled to a team of 16 engineers, successfully raising both series A and B funding rounds. This journey allowed me to gain invaluable insights and experience in scaling operations and managing growth at a start-up / scale-up, while at the same time leading a team to successfully deliver a SaaS platform.My entrepreneurial spirit has driven me to create and launch my own projects. In 2014, I developed an iOS app that was used by major retailers like Toys "R" Us and Marks & Spencer. Additionally, in early 2019 I founded a React & JavaScript tutorial website that became a go-to resource for developers, attracting over 3 million visitors annually.I'm deeply passionate about mentoring and leading teams, helping individuals grow and succeed in their careers. My international experience, having lived and worked in London, Berlin, and New York City, has enriched my perspective and approach to leadership. I also hold a Master's degree from NYU, which has further shaped my professional journey.Outside of work, I enjoy playing the guitar and drums, and I keep fit with spin bike sessions.

Listed skills include Javascript, Html 5, Mobile Applications, Agile Methodologies, and 13 others.
