About

I am a seasoned DevOps Engineer with extensive experience in managing and optimizing containerization services and CI/CD pipelines. Currently, I work at Santander Bank Polska, where I maintain OpenShift clusters, ArgoCD, and Sysdig. I develop and maintain CI/CD pipelines for core banking services and create internal software for virtual machine provisioning, ensuring strict security compliance. My role involves configuration management of both bare-metal and virtual machines using Opscode Chef and developing automation software. Prior to this, I worked as a Cloud Linux Administrator at Microstrategy, where I maintained AWS infrastructure and provided internal application team support. Earlier in my career, I was self-employed as a Linux Administrator and Prestashop Developer, setting up servers and integrating e-commerce stores with various sales systems. At Craftures.com, I administered web stacks and deployed software with Ansible for ephemeral Minecraft instances. At Craftserve.com, I automated server setup with SaltStack and implemented a TProxy solution to optimize Minecraft server costs. My technical skills include expertise in OpenShift, Kubernetes, Terraform, Jenkins, and AWS Cloud, among others. I am proficient in English and Polish, with hobbies in automotive mechanics, electronics, and strength sports.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
