Łukasz Sakwa is a Senior Software Engineer based in Warsaw with five years of hands-on experience building robust Java back-end systems for finance and payments. He has delivered measurable performance gains—such as cutting user-processing time from 30 minutes to 30 seconds—and implemented thread-safe concurrency solutions and secure encryption modules integrating hardware tokens like YubiKey. Łukasz progressed from junior roles at EY, working on audit and crypto transaction systems, to mid-level API and module development at Kyriba, and now contributes to Visa’s engineering efforts. He is expanding into AI through a Data Science master’s program, applying ML thinking to improve software automation and decision-making. Colleagues know him for pragmatic refactors that enhance maintainability and for solving tricky integration and concurrency challenges under production constraints.
