I help CEOs Scale Products, Teams & Innovation

I am passionate about technology and entrepreneurship. I began my career at Oracle Consulting, where I built rapid prototypes for the next generation of single-instance internet systems. After honing my skills at Oracle, my entrepreneurial spirit took over, and six years later, I had founded TVM—a pioneer in video analytics and intelligent command and control. Our team supported high-profile police operations throughout the UK by applying cutting-edge technology to deliver reliable, operational systems. After raising venture capital and growing the business, I sold it to Bowmer and Kirkland and moved on to bet365.

At bet365, the world’s largest online bookmaker, I led the R&D team to tackle the massive scale challenges caused by in-play betting. We adopted novel technologies—such as Erlang, Elixir, Riak, and Go—to ensure the platform remained fast and reliable for millions of users. I revolutionised an industry with groundbreaking systems that were both massively scalable and highly reliable 24*7*365.

After six years, I moved on to lead the innovation team at Lloyds Bank, collaborating with the Bank of England to transform regulatory reporting. One of our key breakthroughs was a domain-specific language (DSL) called UMLANG, which could produce both compilable code and human-readable text to improve transparency and consistency in reporting.

Next, I joined aws in a leadership role within the innovation team, working with their largest customers to identify product gaps. Through customer interaction I uncovered the difficulty customers faced in visualising their evolving cloud architectures. To solve this, I led the creation of aws Workload Discovery, a digital twin that provides greater insight into cloud deployments.

From there, I joined the start-up Huler to bootstrap and launch its fresh employee experience platform, HulerHub. Working with a small team during the pandemic, I successfully brought the product to market on AWS. My next challenge was at Improbable, a metaverse company renowned for creating the world’s most scalable virtual experiences. I led the technical and product teams to adapt this technology for enterprise and defence sectors, successfully onboarding clients seeking next-level immersive simulations.

Having navigated these diverse challenges—from start-ups and scale-ups to innovation roles at major financial institutions and global tech giants—I am now available to help your business and technical teams thrive. Whether you need fractional leadership, strategic product guidance, or a fresh perspective on complex problems, I can provide clarity, innovation, and confidence in your next steps.
