Top SchoolKarol J is a Senior Python Developer with 11 years of experience building robust backend systems, specializing in ETL pipelines, FastAPI microservices, and Airflow orchestration for trading and data-warehouse workloads. He has a strong systems background from earlier C++ work on high-throughput, mission-critical search and device-processing services, which informs his focus on performance, reliability and testability. Karol routinely authors Airflow DAGs and taskflow-based pipelines, writes async FastAPI endpoints, and drives quality through pytest-driven unit tests and thorough code reviews. He prefers fully remote B2B roles with transparent salary expectations and brings proven experience migrating legacy services to modern async frameworks. Based in Krakow, he combines deep practical experience across Python and C++ with an academic foundation from Jagiellonian University. An understated strength is his consistent emphasis on automation and maintainable frameworks that let teams scale data movement and service ownership without sacrificing operational simplicity.
