Wojciech Gdela is a pragmatic Java developer with 12+ years building high-throughput, maintainable systems and a current focus on code quality and performance. He led design and implementation of a financial accounting hub that processes tens of thousands of complex events per second per machine, emphasizes modular testable architecture, and avoids rewrites through relentless refactoring and reviews. Wojciech’s work blends deep concurrency and mechanical-sympathy expertise with hands-on optimizations—evidenced by contributions to the widely used Hazelcast project improving scheduling and transaction performance. He favors automation and rigorous performance/longevity testing, and has built runtime expression compilation capable of millions of evaluations per second. Based in Lower Silesia, Poland, he pairs a pedantic craftsperson’s attention to detail with a tinkerer’s curiosity outside work.
