Eighteen years keeping cloud & networks online, secure & cost-efficient.
I'm Dexter — building and supporting cloud and carrier infrastructure for enterprises, ISPs and telcos since 2009. As a Technical Account Manager I embed with engineering teams as their trusted advisor: architecting solutions, killing wasted spend, and untangling complex networks.
From AWS to carrier networks — the full stack I've worked across
Eighteen years across cloud, enterprise and carrier infrastructure — currently as a Technical Account Manager at AWS, advising ISVs across EMEA on architecture, cost, security and governance.
Cloud cost optimization
Deep experience tracing AWS spend down to the resource level — identifying waste, rightsizing, and designing guardrails that keep costs under control without slowing engineering teams down.
Cloud & enterprise networking
VPCs, Transit Gateways and Direct Connect architected to carrier standards — segmented, resilient and built to scale across regions and into on-prem. BGP, WAN and Zero Trust in depth.
Cloud governance
Multi-account landing zones, security baselines and guardrails that let engineering teams move fast without losing control of the blast radius — built to scale as organisations grow.
Network & systems engineering
A decade of carrier and enterprise routing & switching across Cisco, Juniper, Huawei, ZTE and Ericsson — BGP, OSPF, IS-IS, MPLS L2/L3 VPNs, and high-availability edge design.
DNS, DHCP & IPAM at scale
Authoritative and recursive DNS (BIND9, Infoblox), DHCP at carrier scale (KEA), TACACS+ and IP address management — built and operated at scale across large service provider environments.
Monitoring & observability
NMS and observability stacks from Huawei U2000 to Grafana, Zabbix and Datadog — turning noise into signal with dashboards and alerting that NOC teams can actually act on.
18 years making complex infrastructure work
From network operations centers across Africa and the Caribbean to advising EMEA's fastest-growing ISVs at AWS, I've spent my career keeping critical infrastructure running and helping teams build it better. Earlier in my career I deployed carrier-grade networks across South Africa, Zimbabwe, Zambia, Guyana, Jamaica, Trinidad, Bermuda and more.
Today, as a Technical Account Manager in AWS's ISV-EMEA team based in Stockholm, I act as a dedicated cloud advisor embedded with engineering teams — running Well-Architected Reviews, optimizing costs, designing secure network topologies, and establishing governance frameworks that scale.
A decade-plus as a network and systems engineer across carrier and enterprise environments — multi-vendor routing and switching, core network services, and the monitoring stacks that keep them visible. I ran BIND9 and KEA DHCP serving over 500,000 subscribers.
