Most Proud Of

Zero-Rollback at Enterprise Scale

Migrated 1000+ Linux servers to AWS across multiple production waves at DXC Technology. Every cutover window closed without a critical rollback — the result of dependency gated readiness validation built into every wave plan.

Flagship Program Ownership

Sole TPM on DXC's WFR infrastructure transformation — the largest program in my portfolio. Owned planning, stakeholder alignment, wave execution, rollback governance, and production handover across a 40+ engineer global delivery team.

First Applied AI Delivery

Delivered a LangChain RAG pipeline using ChromaDB at Savvy Global Technologies — expanding from infrastructure TPM into applied AI program delivery and establishing a new capability track in my portfolio.

Professional Highlights

Migrated 1000+ Linux servers (RHEL/SLES/CentOS) to AWS across multiple production waves with zero critical rollbacks, full readiness validation on every wave.
Achieved 15–20% infrastructure cost reduction by designing right-sizing and decommission sequencing into the migration wave structure before execution began.
Led cross-functional teams globally across discovery, validation, and deployment phases using RAID governance, dependencies, & Power BI executive dashboards.
Improved delivery velocity by ~20% at Savvy Global Technologies through sprint restructuring and dependency mitigation across AI-driven program delivery.
Delivered LangChain RAG pipeline (ChromaDB + Ollama) — first applied AI delivery in career portfolio, expanding from infrastructure TPM into AI program execution.
10+ year career arc: telecom OSS/BSS (Huawei, Ericsson, TATA) → Linux infra migration (Adecco) → Enterprise cloud transformation (DXC) → AI delivery (Savvy, CDF).
MS Information Systems, Stevens Institute of Technology (2024–2025) — graduate-level foundation in Digital Innovation, IT strategy, and Machine learning.
