Summary
🤩
RockstarFred Dushin is a pragmatic software engineer and architect with 11+ years building scalable distributed systems and embedded IoT platforms, currently a Member of Technical Staff at Workday in Greater Boston. He prefers hands-on development and has deep experience across languages, OSes, and middleware—demonstrated by significant backend contributions to Riak (including performance-focused refactors) and porting a Tiny Erlang VM to embedded targets like the ESP32. His background spans security, distributed computing, and rigorous testing, with a track record of improving core infrastructure and adding extensive EQC/EUnit coverage. He combines low-level systems work (GPIO, NVS, bytecode interpretation) with large-scale backend engineering, reflecting comfort from microcontrollers to cluster coordination. A lifelong tinkerer, he’s a serial hobbyist in IoT and brings curiosities in cryptography, algorithms, and computational complexity to practical system design. Notably, his view of distributed systems was reshaped by working on Riak, signaling a deep, experience-driven understanding beyond textbook designs.
