About Me
Hi there. I am Bart, a cloud and network engineer. I design and build secure, scalable AWS and Azure infrastructure using Terraform. I focus on automation, strong networking foundations, and production-style delivery.
With 5+ years across infrastructure, support, and networking — including hands-on Palo Alto firewall administration, SD-WAN rollout, and designing Ibstock's full hybrid cloud device estate with Intune and Autopilot — I combine deep technical experience with strong stakeholder communication. My background in corporate banking gives me an edge in translating business needs into scalable cloud solutions.

Featured Projects
Production-style cloud work drawn from my CV, labs, and hands-on builds.
AWS Production-Style Infrastructure
A secure multi-tier AWS build with Terraform: segmented VPC (public / private / isolated subnets), ALB, autoscaling EC2, private RDS MySQL, Secrets Manager, and a GitHub Actions pipeline with drift detection.
↳ Repeatable infrastructure provisioned end-to-end in under 10 minutes via a lint → validate → plan → apply → drift-detect pipeline.
Event-Driven Serverless Pipeline
An AWS serverless workflow using Python Lambda, SQS, DynamoDB, and SNS to process data asynchronously with clean separation between handler code and business logic.
↳ Zero-server architecture handling async processing across three decoupled services with automatic retry and SNS notification on completion.
Azure Terraform Architecture
An Azure translation of the AWS design: VNet segmentation, Application Gateway with WAF, private database access via private endpoints, Key Vault, and NSGs across all tiers.
↳ Multi-cloud parity achieved — identical security posture deployed on Azure proving platform-agnostic infrastructure design.
