PROFILE
Tiago Condeixa
Worked on the zalando-incubator/kubernetes-on-aws repository, delivering upgrades and enhancements to Kubernetes infrastructure on AWS. Over five months, contributed features such as Kubernetes and Karpenter version upgrades, improved deployment and security configurations, and enhanced autoscaling with a Vertical Pod Autoscaler update. Addressed operational stability by rolling back metrics adapters and cleaning up deprecated RBAC configurations, reducing incident risk and simplifying manifests. Used Python, YAML, and CloudFormation to manage infrastructure-as-code, containerization, and networking. Demonstrated disciplined version control and clear documentation, focusing on maintainability, security, and efficient resource management for large-scale Kubernetes deployments in cloud environments.

1 Commits • 1 Features
Jun 1, 2026June 2026 — Focused on upgrading the Karpenter deployment image in the Kubernetes-on-AWS manifest to incorporate latest features and fixes. This was achieved via a targeted manifest update (cluster/manifests/z-karpenter/deployment.yaml), committed as beff09a08c932b6305ae35e44f4a9fb06f0cc672. Major bugs fixed: none identified this period. Impact: reduces risk of running outdated autoscaler components, improves stability and feature readiness, and reinforces disciplined manifest-based change management. Technologies demonstrated: Kubernetes/Karpenter, YAML manifests, Git/version control, and infrastructure-as-code practices.

Apr 1, 2026April 2026: Focused on stabilizing the metrics pipeline for kubernetes-on-aws. Key action was rolling back kube-metrics-adapter to the stable v0.2.8, which restored reliable metrics collection and prevented monitoring regressions. The rollback was implemented with a single revert commit for clear auditability and quick future reversals if needed. This work reduced incident risk, preserved SLA for monitoring, and kept telemetry aligned with known-good behavior. Technologies demonstrated include Kubernetes, container image management, and incident-driven rollback procedures on AWS-based deployments.
