About
Backend engineer with 5+ years building production-scale distributed systems. My work spans event-driven microservices serving millions of users and protocol-level upgrades to large, live peer-to-peer networks. I thrive in small, fast-moving teams with high ownership and high engineering standards.
Iām especially interested in developer tools, AI, and event-driven systems.
Writing
I love breaking down dense protocols and systems into approachable pieces. My deep-dive technical posts on Bitcoin and Lightning Network internals have been widely read and well received across the community.

Work

2021 to Present
One of the top contributors to LND, the most widely-deployed Lightning Network implementation. My work centres on shipping protocol upgrades and large database migrations safely across a live peer-to-peer network of thousands of nodes. I also lead major features in the Lightning Terminal and Lightning Node Connect developer tooling.
