Who am i?

I'm Jack Spargo, an Engineering Leader

I've spent the last decade working for myself, employers and clients to solve problems using computers. As well as building software for banks, supermarkets and the public sector, I've also used technology to simplify processes and make life easier where I can. I'm passionate about building things that are delightful to use and that make sense to users. Whether as a consultant or on my own side projects, I believe in quality and simplicity in the software building journey. Anyone can code and everyone should try it. With the right quality gates, a continuous delivery and integration process and a positive learning culture, every organisation can support their teams to deliver high quality software alongside their learning and development. If you want to talk to me about any of this or you are wondering how your team can work smarter, not harder, please do get in touch.

My work

Builder. Leader. Engineer. Entrepreneur

Since graduating in 2010, I've worked across a range of industries, primarily in the roles of technologist, software architect and software engineer. Currently I'm the CTO at Ctrl Alt, a FinTech platform for alternative assets. Previously I was the CTO at Strikepay - a cashless tipping and payment platform. This was a role I took on when Strikepay acquired Gratsi, a company I founded in 2020:

  • 2010 - 2013 - Accenture
  • 2013 - 2017 - Deloitte Digital
  • 2017 - 2020 - ShopKeep
  • 2020 - 2022 - Gratsi / Strikepay
  • 2022 - 2023 - Consulting & fractional CTO
  • 2023 - present - Ctrl Alt

In the final year of my Masters degree I wrote a dissertation on how the UK can use Carbon Capture and Storage (CCS) to lower it's carbon dioxide emissions and meet it's environmental targets. This was adapted into a paper that was published by Elsevier's Energy Conversion and Management journal.
