Selected engineering work
Platforms built for reliable delivery.
Three focused case studies covering event streaming, day-two Kubernetes operations and repeatable AWS infrastructure. The architecture and decisions are public; private source code remains private.
Flagship case study
Kafka Streaming Platform
A three-node Kafka KRaft pipeline with replicated state, Python services, PostgreSQL, Strimzi and six dependency-ordered ArgoCD sync waves.
- Objective
- Ingest, process and expose IoT-style sensor events reliably.
- Ownership
- Architecture, containerization, Kubernetes runtime and GitOps rollout.
- Evidence
- Replication factor 3, minimum ISR 2, persistent storage and sync waves 0-5.
Platform operations
EKS Platform Tools
Karpenter and day-two EKS tooling backed by a 22-day Cost Explorer report showing 100% Spot usage.
Infrastructure automation
EKS Terraform Infrastructure
Three-AZ Terraform foundation with six subnets, IPv6-primary workers, seven service endpoints and a 1-5 node scaling range.
AI-assisted product and engineering workflows
FitBack Coach and the documentation/QA process are presented separately from the cloud infrastructure case studies.
