BEN TARTAGLIA

EXECUTIVE PROFILE

Technology operations and architecture leader with 20+ years spanning enterprise infrastructure, Microsoft 365 and Entra ID, Active Directory, Windows Server, networking, identity and access management, security, automation, IoT/edge systems, and distributed support. Current work extends that discipline into Trusted AI Operations: measurable accuracy, provenance, risk-based human oversight, observability, safe failure, and controlled production adoption.

SELECTED BUSINESS & TECHNICAL IMPACT

• Enterprise reliability: Supported 2,200+ users across 89 locations while sustaining 99.99% availability in a distributed operating environment.
• Identity modernization: Supported hybrid identity and SSO work involving approximately 1,300 Microsoft 365 accounts across Active Directory and Entra ID.
• Automation: Built PowerShell/Python and API-driven workflows that reduced manual effort by approximately 30% and improved consistency.
• Operational improvement: Standardized deployment verification and root-cause practices, reducing deployment-related errors/downtime by approximately 25% and improving recurring-issue resolution by approximately 30%.
• Security: Strengthened email security with SPF, DKIM, DMARC and threat analysis, contributing to an approximately 80% reduction in phishing incidents.
• Service analytics: Audited 81 Zendesk fields and approximately 540 support tickets to identify routing gaps, recurring failure patterns, workflow friction, and documentation opportunities.

CURRENT TECHNICAL PROOF OF WORK

• Automation Operations Platform: TypeScript/PostgreSQL reference platform with queues, idempotency, approvals, retries, dead-letter handling, Prometheus/Grafana, hardened Docker, GitHub Actions, and AWS Terraform.
• Enterprise Identity Reference Architecture: Entra ID lifecycle, RBAC, privileged access, Conditional Access, emergency access, workload identities, audit/incident response, and PowerShell assessment patterns.
• AI Model Longitudinal Lab: Multi-provider evaluation architecture with provenance, prompt/schema versioning, structured-output validation, evaluator separation, and token/cost accounting.
• IoT / Edge Reference Architecture: Offline-first BLE/RFID/NFC patterns with buffering, deduplication, store-and-forward synchronization, connectivity resilience, and operational handoff thinking.

WHERE I ADD THE MOST VALUE

Complex environments where technology has outgrown the operating model: fragmented ownership, recurring incidents, weak documentation, inconsistent deployment practices, integration sprawl, field/edge constraints, or automation that needs stronger reliability and governance. I work to make the system more observable, supportable, repeatable, and easier to hand off.
