Rockstar🎓
Top SchoolDimitris Sarlis is a Staff Software Engineer with 12 years of experience building backend systems for distributed and blockchain platforms, currently based in Zurich. He has held progressive roles at DFINITY—contributing to Internet Computer core components and leading backend efforts for Internet Identity and Bitcoin canisters—and previously engineered infrastructure at Meta. Dimitris excels at integrating complex external systems (e.g., Bitcoin) into canister-based architectures, optimizing resource management and persistence in constrained runtime environments. His background blends rigorous academic training from Carnegie Mellon with hands-on big-data and cloud scheduling research, giving him a strong foundation in scalable system design. Colleagues know him as a pragmatic team lead who ships production-grade features (asset serving, non-UTF8 support, stable storage, auth) while tackling subtle issues like cycles accounting and heartbeat execution. Outside obvious delivery metrics, he brings a track record of turning research prototypes into robust engineering solutions across both academia and industry.
