About Alexander
I’m currently transitioning from a PhD program to industry, leveraging my strong technical background to build scalable, efficient, and automated cloud solutions. Freelancing allows me to apply and expand my expertise in DevOps, cloud infrastructure, and automation, working on real-world projects that drive impact.
With a deep understanding of Docker, Kubernetes, and Linux systems, I specialize in designing and optimizing CI/CD pipelines, cloud deployments, and containerized environments to help businesses streamline their workflows.
🔧 What I Bring to the Table:
✔️ CI/CD Pipelines – Automating deployments with GitHub Actions & GitLab CI/CD
✔️ Containerization & Orchestration – Expert in Docker, Docker Compose, Kubernetes & Helm
✔️ Linux Administration – Managing and securing Ubuntu & Debian environments
✔️ Scripting & Automation – Crafting Bash & Python scripts for efficiency
✔️ Web App Testing & Debugging – Using Selenium for robust quality assurance
As I transition into the industry, I’m eager to take on challenging projects, apply my skills to real-world problems, and collaborate with innovative teams. Let’s connect and build something amazing!
