I am currently employed as a Network Operations Center Engineer at Multi-Telekom, where I manage carrier networks, set up monitoring systems using tools such as Grafana, InfluxDB, Prometheus, and LibreNMS, and coordinate field engineers. My role also involves managing virtualized systems based on Debian and Ubuntu, creating internal systems for customer access and billing management, and overseeing MySQL databases. In addition, I have been freelancing as a Linux System Administrator and Node.js Developer at Houseware since March 2021, where I manage customer networks and virtualized environments using VMWare ESXi, Proxmox VE, Microsoft Hyper-V, and XCP-NG, while actively monitoring for security events and creating internal systems with Node.js. As a DevOps Engineer, I have been contracted with DreamProject and SimPay / Payments Solutions since August 2020. At DreamProject, I prepare development environments, maintain network services, and administer servers with Proxmox VE-based virtualization. My responsibilities also include database profiling, creating network infrastructure, and coordinating security operations. At SimPay, I create microservices architecture for the financial sector, manage RBAC for developers, set up CI/CD processes, and continuously harden network infrastructure. My previous experience includes roles as a Linux System Administrator at DX-IT, where I prepared network infrastructure for the video game sector, and as a Linux System Engineer at PALLOX Paweł Chwastek, where I managed carrier networks and implemented automation scripts. I hold an IT Technician degree and possess skills in Kubernetes, Docker, Ansible, Terraform, and various programming languages.Tech Stack
