Hi, I’m Mateusz Ciesla, a full-stack and DevOps engineer who designs and runs large-scale data platforms and distributed infrastructure. I enjoy turning complex requirements into robust, scalable systems using Python, Rust, Go, and Node.js, with a frontend in React. I’ve designed Kubernetes clusters on cloud and dedicated servers, automated infrastructure with Terraform and GitLab CI, and built containerized pipelines with Docker. I’ve delivered data warehouses and BI workflows serving millions of users, optimized SQL for low-latency queries, and built advanced systems such as a Rust FIX protocol framework, RAG pipelines powered by LLMs, and large-scale scrapers with real-time monitoring. I’m currently pursuing a B.Eng. in Computer Science and Information Systems at Warsaw University of Technology (expected 2026) while maintaining a fast promotion track.
