Rockstar🎓
Top SchoolLukas Joswiak is a software engineer with five years of experience building reliable, system-level infrastructure and distributed systems from Seattle. Currently at Snowflake, he works on FoundationDB internals—contributing tracing, span context, and transaction persistence fixes to a widely used open-source distributed transactional key-value store. His background includes internships at Facebook, Apple, and Blue Origin where he improved network recovery and synchronization, built integrity APIs, and enhanced background client infrastructure. As a teaching assistant for multiple systems and distributed systems courses at the University of Washington, he pairs research-informed rigor with practical engineering. He brings a knack for observability and low-level performance work that quietly improves system debuggability and resilience.
