I enjoy building the “operating system” behind communities — processes, tools, automation, and reporting — so teams can move quickly without chaos.

What I build for teams

Automated comms: email workflows, reminders, task notifications, approvals.
Self-hosted tools: portals, internal knowledge hubs, search, dashboards.
Reliable ops: roles, checklists, templates, and “runbooks” for events and committees.
Data clarity: simple reporting that decision-makers actually use.
