  • Held DevOps, IT, and InfoSec simultaneously at a 220-person gaming/blockchain company — historically three separate hires — with a combined budget of ~$300–350K/yr
  • Built IT helpdesk from zero: eliminated the 30%+ month-long backlog pattern and achieved 45-min average resolution through workflow redesign and automation — without adding headcount
  • Delivered ~$100K/yr in cumulative FinOps savings over tenure — through continuous AWS cost review, resource consolidation, and vendor rationalization (35% IT infra reduction; 40–70% on DevOps projects)
  • Commissioned external Gap & Risk analysis of 100+ data assets (Estonian security firm); built ISO 27001 risk register, asset inventory, and access-review cadence from scratch — program built and scheduled for audit
  • Replaced zero-observability posture (manual CTO-office escalation, days-to-weeks MTTR) with SLO-driven Prometheus + Grafana + Loki + FluentBit stack and on-call playbooks
