Kevin Medeiros — Head of DevOps

whoami

A DevOps leader who turns sprawling infra into calm, automated systems.

Highly skilled, results-oriented and obsessed with the boring kind of reliability — the kind nobody notices because nothing breaks.

Over 9+ years I've designed, implemented and maintained robust, scalable systems — with a proven track record of optimizing processes, improving efficiency and reducing cost across AWS, Google Cloud and Kubernetes (Rancher / k3s).

My work centers on migrating services into containerized environments, GitOps automation and observability. I'm proficient in Python & Java, and I've led and mentored engineering teams the whole way — currently as Head of DevOps at NovumDMS.

Remote

Directed infrastructure & dev processes across an AgriTech/IoT platform, a multi-tenant SaaS ERP layer and a modern distribution ERP.
Led a full GitOps migration with ArgoCD across all product environments — standardizing deployments and improving reliability, traceability & auditability.
Designed & operated k3s clusters on GCP, managed through Rancher, with secure secret management using SOPS + AGE.
Deployed a production MQTT broker (EMQX on Kubernetes) with mutual TLS, ECDSA certificates and TLS 1.3 for secure IoT device integration.
Launched a FinOps initiative inventorying third-party services & GCP spend — surfacing savings via committed-use discounts and storage optimization.
Diagnosed & resolved production incidents across Kubernetes networking (Flannel/VXLAN), MongoDB indexing and RabbitMQ reliability.
