Built for the hard parts.
Bitcoin consultancy for product teams, protocol builders and infrastructure operators. Bring a product brief, integration gap or unreliable stack.
Bitcoin product engineering
Wallet UX, Lightning payments, privacy-focused transaction flows, LNURL, submarine swaps, Nostr and payment-gated product experiences.
Protocol & wallet integration
Architecture, proofs of concept, upstream contributions, testing and production-minded handoff.
Infrastructure & hosting
Node-connected services, Docker, reverse proxies, release automation, monitoring and operations.
AI-assisted development
Agentic workflows for prototyping, implementation, testing and operations, with working software as the output.
Ways to work together / 06
Bring the problem. I can own the build.
Best suited to focused engagements where technical direction and implementation need to stay connected.
Focused product build
Turn a product brief or protocol opportunity into a working application, from architecture and UX through deployment.
Embedded engineering
Join an existing team to ship a wallet, payment or protocol integration without adding another handoff layer.
Technical intervention
Stabilize, extend or productionize an existing Bitcoin system when reliability, privacy or operations need senior ownership.
