About Victor

I am a Senior DevSecOps and Kubernetes Architect with a background in Cyberdefense and Critical Infrastructure. I specialize in designing and industrializing secure, resilient cloud-native platforms for scale-ups and high-stakes environments.


I operate on a hybrid freelance model, offering two types of 100% remote engagements:

🛠️ 1. Core Engineering & Build (2 to 12 months):

Integrating with your team to lead complex infrastructure migrations, automate cluster provisioning (OpenShift/Hypershift, K3s, custom operators in Go, complex workflows in Python, Gitops) and implement Shift-Left DevSecOps pipelines. I have a significant record deploying Kubernetes infrastructures in critical environments and airgaps.

🚀 2. Architecture & PoC Sprints (3 to 4 weeks):

A commando-style intervention for teams needing rapid infrastructure design. I deliver complete High-Level and Low-Level Designs (HLD/LLD), followed by a coded Proof of Concept and comprehensive Production Guidelines to accelerate your internal teams.
Stack: Kubernetes, OpenShift, K3s, Python, Go, Terraform, ArgoCD, Tekton, OPA, Traefik, K6, Kagent.
Focus: High Availability, Air-gapped environments, Zero Trust Architecture.
