Aleksander Czeszejko-sochacki is a Scala-focused software engineer with 8 years of experience building functional, concurrent systems and data-driven services while working remotely from Lower Silesia, Poland. He has designed and implemented purely functional microservices, Kafka-based data pipelines, and crypto payment integrations using the Typelevel stack (cats, cats-effect, fs2, http4s) and cloud-native tooling (Docker, Kubernetes, GCP). His background in algorithms, pathfinding and probabilistic models from data-science roles informs pragmatic solutions to large-scale geospatial and streaming problems. Comfortable bridging research and production, he has applied Python ML tools (scikit-learn, pandas) alongside Scala to deliver analytics, NLP and recommendation components. An interest in programming languages theory shows in his preference for principled, type-safe designs that make concurrent systems more predictable and maintainable.
