Description

I design, build, and fully automate secure, scalable, and high-performance cloud network architectures — with deep expertise in complex multi-account, multi-region AWS and hybrid environments.

What I deliver:

End-to-end hybrid connectivity: Transit Gateway, Direct Connect, PrivateLink, Site-to-Site VPN, VPC Endpoints

Advanced networking automation using Terraform + GitOps for repeatable, version-controlled deployments

Low-latency, resilient, and secure network designs for business-critical workloads

Large-scale AWS migrations, landing zones, and environment separation programmes

Centralized egress, inspection, and routing across multiple AWS accounts and regions

With over 20 years in infrastructure and networking (and 10 years focused on AWS), I help organisations reduce operational risk, eliminate manual processes, and accelerate their cloud journey.

Currently operating through my UK limited company (Mplexia Limited) and immediately available for remote UK/EU contract roles (£500/day).

Open to 3–12 month contracts or shorter missions. Happy to jump on a quick call to discuss your needs.
