About

I mend, break and fix things to learn how they work. Twenty years of hands-on tech. By day I lead information security and GRC at a UK startup. Evenings and weekends, I build the tools I wish existed. Innovation is what I love. Security is the proof I can be trusted with it. I'm neurodivergent. I spot patterns early, link problems to fixes, and learn new things fast. Maker of Gridlark: turn the Google Sheet your team avoids into an app. No migration, no AI. Founder of AI2B Ltd and Left Foot Forward Away from screens: an allotment, some bees, and The Plotcast. No experts, no rush, no perfect rows. Always happy to hear from people who like building things together.

Gridlark - Turn the sheet your team avoids into an app they'll use.

Every team has a Google Sheet nobody else dares to touch. Gridlark gives it an app: dashboard, search, guided forms, and Approve and Mark done buttons. The sheet stays the source of truth, and formulas are never overwritten. The app is plain Apps Script in your Google Workspace, so your data never passes through us. No AI: written rules propose every field, each with its reason, and the same sheet always gives the same app. One price per organization, never per seat. One live app is free.
