Scouting report
Backend/ML engineer; built a Python RPC lib for Crown nodes
assessed from open-source footprint
Staff
58signal
Adrian is a Havana backend engineer with a 7.7-year account, 18 original repos, and genuine range across Go, Python and Jupyter (backend 45%, Data/ML 25%). His standout is crown-pycurl, a Python library for interacting with Crown blockchain node RPC over curl — a real tool, though only 1★. The big caveat is a high abandonment ratio (0.67); a solid mid-to-senior backend pick if you value applied breadth over polish.
