I work fulltime on open-source Bitcoin projects and are currently supported by a Brink.dev Bitcoin Developer Grant. In 2021, Coinbase supported me with a Coinbase Bitcoin Developer Grant. I run mempool.observer, the Bitcoin Transaction Monitor, transactionfee.info, the miningpool.observer, an open-content and educational blog called bitcoin-dev.blog, and have worked on a lot of other projects over the past years.
I use the GPG key with the fingerprint
982A 193E 3CE0 EED5 35E0 9023 188C BB26 4841 6AD5 and without spacing
The public key can be found here and on the ususal key servers. There is also a key transition notice (February 2021) for a key I previously used.
I’m currently only avaliable for short-term Bitcoin freelance and consulting projects. My main focus lies on open-source projects.
