It Scales Until It Doesn't

Co-presented with Dmitry Tiagulskyi. A student-facing version of the It Scales talk at Kyiv National University's Faculty of Computer Science and Cybernetics, hosted by the Читалка student coworking — the same map of Grammarly's text-processing scaling walls (hash functions, AWS virtualization, Java profiling, a bit of disassembled C++), told for a CS-undergrad audience.
