Marcin Sciesinski is a seasoned Java architect and server-side engineer with 25 years of architecture, design and development experience and a 13-year track record of delivering large-scale, high-throughput systems for telco and cloud providers. He built and scaled Personal Cloud platforms deployed by Tier-1 operators worldwide and authored a Netty-powered batching server to handle thousands of concurrent requests. Now based in Chiang Mai, he focuses on remote contract roles and blends enterprise-grade backend expertise with a hobbyist’s passion for game programming and tools development. His background spans performance tuning, refactoring legacy banking systems, and driving asynchronous, big-data server solutions—skills that make him equally comfortable optimizing throughput or prototyping game tools.
