Aleksandar Todorović

Senior DevOps Engineer with a strong focus on keeping systems secure. Motivated, independent learner, able to quickly take ownership of different tools and processes. Passionate about documenting his work. Accustomed to working in smaller (3-5 people) infrastructure teams.

I'm based in Sarajevo, Bosnia & Herzegovina and able to work in CET-compatible timezones. If you need a full-time contractor to take ownership of your infrastructure or a surge hire to get you over the finish line, feel free to reach out.

Where I've worked

Some of the fun problems I've tackled

• Moving bare-metal infrastructure into the cloud.
• Bootstrapping Kubernetes clusters using Terraform.
• Creating a platform that allows developers to bootstrap their projects with pre-configured CI/CD, vulnerability scanning, and monitoring already wired up.
• Designing SRE strategies that are suitable for a small team, including disaster recovery procedures and defining SLIs and SLOs.
• Building LLM agents that reduced the volume of inbound tech-support tickets.
• Handling the compliance work for an app-based medical product available in several markets.
• Responding to security incidents, writing good incident reports and learning from them is something I thorougly enjoy doing.
• Training at-risk journalists on how to communicate more securely.

Outside of work

I'm a member of the Internet Society's local chapter, and I run samo.house, a music website that lets me work on parts of the stack I don't touch in my daily job, such as backend and frontend development.

I was a maintainer of GitHub's awesome list and an owner of awesome-linux and awesome-c, which have >4k stars each. I'm still the most-starred GitHub user from Bosnia & Herzegovina. I've also written for Opensource.com, including a piece that won a Reader's Choice award.
