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.

Kafka streaming platform architecture

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.
