Kozheen Taher Esa

Test Automation Engineer · Medical Software @ Cancer Treatment

Optimizing CI/CD pipelines for software that treats patients. When a pipeline fails here, it's a patient waiting — so I make the path from commit to production boring and predictable.

👋 About

Previously at Nokia (4 yrs) — built their AI/ML platform from bare metal: 52+ GPUs, KubeVirt clusters, self-service Jupyter, and a validation system that cut hardware compliance checks from manual hours → automated minutes. Stint at Netlight migrating IaC from AWS CDK → Terraform.

I care about fast reliable pipelines, observable systems, and writing the guide so the next person doesn't need to ask me.

Most of my work lives in private corporate repos — the public ones are tools I use myself.
