I'm Aleksander Baska, a backend engineer focused on building scalable, production-grade systems.
I enjoy designing and implementing distributed architectures, event-driven pipelines, and AI-powered platforms treated as backend workloads rather than experiments.
If a system looks complex, asynchronous, or hard to scale - chances are I want to build it.
