Translating high-level architectural patterns into working configurations for lean teams without enterprise bloat.
Identity & Infrastructure Strategy

- High-availability network topology reviews built for actual recovery.
- SSH key orchestration and service credential isolation.
- Translating zero-trust theory into affordable SMB configurations.
Diagnostics & Root-Cause Escalation
- Packet-level forensic captures (Wireshark) to isolate dropped traffic.
- OS and proxy bottleneck debugging when third-party software stalls.
- Deciphering hostile server stack traces into straightforward action items.
- Sub-contracted senior engineering support for local MSPs.
The Principal's Pedigree
10+ years in enterprise IT and still figuring it out every day. The only difference is that now I read the raw packet trace before panicking.
