David Daeschler is an experienced technology leader and founder with 14 years in software and over three decades of hands-on engineering through ventures like SlideWave and InWorldz. As EVP of Data Science & AI (previously CTO) at OneRail, he drives data-driven optimization and orchestration for final-mile logistics, improving speed, dependability, and cost for enterprise deliveries. He blends executive strategy with deep technical chops—having written low-level C fixes for cross-platform projects like psutil to resolve memory leaks and improve CPU affinity on Windows and Linux. His background spans distributed systems, compilers, virtual machines, and scalable storage solutions, reflecting a pattern of solving performance and reliability challenges at scale. Based in Orlando, he combines product-focused UX sensibilities from SlideWave with rigorous architecture and operational experience. Notably, he has a track record of moving research-grade systems (virtual world runtimes, NoSQL inventory stores, physics engines) into robust production deployments.
