About

Enterprise background.
Cloud focus.

I'm a Network Analyst at Visa with close to four years of experience working within enterprise financial infrastructure — the kind of environment where uptime is non-negotiable and change control is religion.

I'm actively transitioning into Cloud and DevOps engineering, building hands-on AWS projects alongside my current role. I don't just read documentation — I build things, break them, and fix them properly.

My network background means I understand the infrastructure layer that most cloud engineers treat as magic. That's a genuine edge when designing secure, well-architected systems.

Production-Grade Flask App on AWS EKS
A full DevOps platform built from scratch — local Docker Compose stack through to a live, auto-scaling Kubernetes deployment on AWS with automated CI/CD. A Python Flask API serves health, metrics, and readiness endpoints. The monitoring stack (Prometheus, Grafana, Alertmanager, cAdvisor, Node Exporter) runs alongside the app. Infrastructure is provisioned via modular Terraform across four modules: vpc, eks, ecr, and cloudflare. Kubernetes manifests handle deployments, ingress, HPA, and cert-manager SSL. Every push to main triggers a 3-stage GitHub Actions pipeline: test → build & push to ECR → deploy to EKS. OIDC authentication throughout — no long-lived AWS credentials stored anywhere.

Modular ALB + Private EC2 Infrastructure
Production-style AWS infrastructure built with Terraform. An ALB routes traffic to private EC2 instances inside a custom VPC — no direct internet exposure. Refactored from a flat layout into a three-module architecture (vpc, alb, compute) using moved.tf blocks to eliminate state destruction. Reduced a 19-destroy plan to zero.

ALB + Private EC2 (Console Build)
The original hand-built version of the same ALB architecture — deployed via AWS Console before being codified in Terraform. Documents the manual process and serves as a reference for understanding what the IaC automates beneath the surface.

2022 – Present
Visa
Network Analyst
Working within Visa's enterprise financial network infrastructure on a rotating shift pattern — the kind of environment where reliability isn't a target, it's a baseline.
  • Managing and monitoring enterprise-grade network infrastructure supporting global payment processing
  • Participating in incident response, root cause analysis, and structured change management processes
  • Operating in a high-availability, high-compliance environment with strict change control
  • Applying network fundamentals (routing, switching, DNS, firewalls) daily in a production financial context
