Founder   2025-Present

Digital inheritance vaults for everyone. Would your family be able to access your devices, email, photos, cryptocurrencies, and accounts if you passed away? People's digital lives are getting larger, but there is no secure way to pass on your digital estate. Drawing on the security architecture of leading messengers and password managers, Upon is an end-to-end encrypted vault designed specifically for end of life.

Founder   2023-2025

The big goal was to replace email. Slack is so easy to use but internal-only, so we built a protocol that's fully backwards compatible with email but enables instant messaging, end-to-end encryption, identity verification, and more. We left it at prototype stage because we couldn't find a route to market, but I will always love to talk about the future of messaging.

Early hire at one of the world's most secretive quant hedge funds. I absolutely loved it. I couldn't recommend a better place to work, but I always promised myself I'd build more start ups.

Hobby Projects

2000s-2010s

When I was nine years old I asked my parents for 'C++ for Dummies' at Christmas. I broke and fixed many installs of Linux. Built many Minecraft Redstone contraptions which inspired me to learn Java through The New Boston's Youtube tutorials. Created my first website aged 11 and it's still online for friends to laugh at. Wrote unfinished game engines, a chat client-server, and a Minesweeper clone. Built a 7970 Bitcoin mining rig back in 2012 but didn't keep it running for long enough. Sold a bunch of Tumblr themes online, including a bespoke one for MVMT.
