Experience
- Built an always-on, cloud-free on-prem multi-agent LLM cluster on 15 Mac Studios over Tailscale, auto-recovering on reboot
- Designed a normalized 27-table call-center/customer schema - passed 2 external reviews and adversarial code review
- Automated work logs and daily reports on access-isolated Hindsight memory plus a Graphify knowledge graph
- Shipped 2+ MVPs solo: OurFolio (evidence portfolios), ASHD v2 (OCR+LLM warranty mgmt, eval gates), BluePy 2.0 (open-source security scanner)
- Operated BK-HQ: 15 AI agents, 4 teams, 31 skills, 19 automation hooks, and 5 crews
- Open-sourced (MIT) Hindsight-Crew · memory-bench: agent-memory tenant isolation proven by 9 executable gates - 4 adversarial bypasses rejected, fully offline, measured
- Applied POS data to demand forecasting, inventory optimization, and customer analysis - the move into AI/ML
- Monitored 20+ Fortinet WAF/IPS/UTM/SIEM appliances for 50+ clients, 1,000+ events monthly - false/true-positive accuracy +50%
- Ran the full CERT lifecycle (detect → analyze → block → policy → report) - automation cut handling 30 min → 5 min
