Self-taught backend and infrastructure engineer. For five years I've been the sole on-call engineer for production crypto infrastructure: a multi-operator custody system safeguarding $200K across 7 independent operators, 15 containerized services, and the Prometheus/Grafana monitoring and automatic failover behind them.
I also built ccnodes.net, an API service running archival nodes for 9 blockchain networks (~2 TB kept in sync at tip), with two different indexer engines normalized behind one REST API.
I enjoy building software, I do it for fun or for pay.
Looking for backend, infrastructure, or API roles. Happy to walk through any of it.
