Selected engineering work
Four independent projects covering streaming, Kubernetes operations, infrastructure and delivery. Each case study documents my implementation, the tradeoffs and the evidence behind the result.
Every architecture, measurement and demonstration shown here comes from my own project environments. No former-employer source code, configuration, customer information, infrastructure inventory, budgets or production metrics are presented.
Flagship case study
I built a sensor-event pipeline with Python services, a three-node Kafka KRaft cluster and PostgreSQL on Kubernetes. Application logic, stateful infrastructure and the ordered Argo CD rollout are managed separately.
Platform operations
I built an EKS operational layer with workload-aware provisioning, shared observability and scoped CI runners. A 22-day Cost Explorer report records 100% Spot usage in this project environment.
Infrastructure automation
I defined the networking, identity and cluster boundaries as separate Terraform responsibilities: three availability zones, private IPv6 workers, seven service endpoints and controlled scaling.
Live delivery infrastructure
Terraform manages a Route 53 and CloudFront delivery path backed by a private S3 origin. Deployment, cache invalidation, origin isolation, TLS and cost controls are documented as operational evidence.
