About Sergio Arenas
Service-delivery & vendor-management leader for large retail tech environments. I orchestrate multi-site network/voice rollouts (fiber + LTE/5G + VoIP), hold suppliers accountable with KPI scorecards, and partner with Finance/AP to control the invoice-to-pay lifecycle. My teams have delivered 700+ store turn-ups/year and multimillion-dollar savings through rate renegotiations, inventory normalization, and SLA credit recovery. I’m hands-on with PMO cadence (RAIDs, risk/esc), TEM controls, and change management — and I love turning messy, cross-vendor programs into predictable delivery.Interests: Service Delivery/Director, Infrastructure/Network TPM, Vendor/Supplier Mgmt, TEM. Keywords: SD-WAN, VoIP/UCaaS, circuit provisioning, SLA governance, TEM (Sakon/Tangoe/Calero), MTTR/OTIF, QBRs, Tableau.
