06 / ACTIVITIES
Performance Management Tool
Personal · Ongoing
Building a lightweight performance management tool for team leads — scoped, built, then paused pending real user feedback before pushing further. Not every side project needs to ship; some need to sit and be tested against actual use first.
Self-Hosted Infrastructure
Personal · Ongoing
Run a home lab covering email (Soverin + PGP), DNS filtering, monitoring (ELK), password management (Vaultwarden), and workflow automation (n8n) on a VPS with Tailscale networking. Where the architecture opinions get tested before they reach client work.
Cooking & Gardening
Personal · Ongoing
Kitchen and garden as the other systems I maintain — one with recipes instead of runbooks, the other with a lot more waiting for feedback loops to close.
