GitHub Sponsors Profile

I have authored or contributed to ~100 packages on npm which have collectively been downloaded over 20 billion times! These packages are used in production by companies like Facebook, Netflix, Google, Microsoft, Twitter, Airbnb, Coinbase, and GitHub, as well as by millions of individual developers around the world.
I'm also very interested in Bitcoin. I've made significant contributions to the @browserify and @bitcoinjs projects to bring the latest Bitcoin features to JavaScript. I've published some libraries and educational sites related to Bitcoin and have added privacy improving and recovery features to wallets such as Electrum and BlueWallet.
Security research is something that I do a lot of too. I help keep open source software secure by responsibly disclosing any vulnerabilities I find without any expectation of payment. Here's an example of one of my disclosures of a critical vulnerability in an open source password manager: https://github.com/buttercup/buttercup-browser-extension/issues/92.
And finally, I'm very passionate about privacy and censorship resistance. I've been running a Tor relay since 2013. I also run a Bitcoin full node with a public Electrum server available over clearnet (bitcoin.lu.ke) or as a Tor hidden service (lukebtcygzrosjtcklev2fhlvpbyu25saienzorhbf3vwc2fpa475qyd.onion). This node serves thousands of users concurrently and is depended on by major Bitcoin wallets.
Currently most of my time is spent focused on my startup @getumbrel. I have limited time outside of Umbrel to work on FOSS, so I no longer accept recurring monthly donations. However if you've benefited from some of my existing FOSS work or want to help with running costs of my servers then a one off donation is always appreciated.
If you prefer Bitcoin you can donate on-chain or via Lightning.
