My work

I help fast-growing tech teams solve problems and grow. I also perform technical due diligence for venture capital firms, as part of their funding process.

I work with most of my clients for either half a day or one day each week, but I also take on one-off projects. I try to always reserve some time for new clients facing an emergency, so if you're in the middle of a crisis please get in touch, and I'll do what I can.

I'm often asked to solve technical problems, like rearchitecting software, replatforming, choosing technologies, or firefighting urgent performance problems and scaling issues.

I also work with clients on technical management problems, either alongside an existing CTO or acting as the CTO. This work can include making key technical hires, improving processes and communication between teams, making software teams faster and more effective, or just maintaining progress while we find a permanent tech leader.

With many clients, I also help them solve general commercial problems: improving their understanding of their customers, improving non-technical processes to increase revenue (e.g. sales and onboarding processes), reaching product-market fit and coping with exponential growth.

I've worked on scalable web apps, beautiful responsive desktop apps and mobile apps, highly optimised supercomputer software, robust B2B automation tools, digital hardware projects, and everything else in between. I've worked in a wide range of technologies and industries too, from prototypes to fast-growing products being used around the world, so I'm happy to jump into any project in any team that wants to grow fast.

My background

I've been writing software since I was 9, and have a degree in Computer Science and Machine Learning from Cambridge University.

I've been a Founder/CTO and Consulting CTO for a variety of companies since 2010.

Sam Morgan, CEO of Handcrafted

Hywel is a rare developer: communicative, responsive, and utterly obsessed with the finer details. He knows code inside out, but knows how to handle humans, too.

Richard Bridgwood, Chairman at Si5 Spy Missions Ltd

Hywel is an experienced software engineer and CTO who also understands the consumer, consumer behaviour and marketing. He is able quickly to identify the gaps in a startup idea and produce creative ways to solve them, saving business owners time and money. His skillsets are not often found together and make a powerful combination which I can highly recommend.
