Suleiman Abdulrahman

Cloud Infrastructure & DevOps Engineer

I design and operate production-grade cloud infrastructure, CI/CD pipelines, and distributed systems. Infrastructure as Code, Kubernetes, observability, and security-by-default are my building blocks.

What I've Built

Production-grade infrastructure platforms, security automation, and distributed systems.

Flagship

nexuspay-platform

Flagship fintech microservices platform on AKS with Istio mTLS, ArgoCD GitOps, Prometheus/Grafana/Loki observability stack, and Helm-based deployments. 4 services with blue-green and canary rollout strategies.

Project

vpcctl-linux-networking

Python CLI simulating AWS VPC networking from first principles — Linux network namespaces, bridges, veth pairs, iptables. Zero cloud account required.

Python Linux iptables Networking CLI
Project

aws-cost-security-auditor

CLI scanner detecting AWS cost waste (idle EC2, unattached EBS) and CIS-aligned security misconfigurations (public S3, permissive SGs). JSON + Markdown output with severity scoring.
