Summary
👤
Senior🎓
Top SchoolDavid Walter is a founder and engineer with eight years of experience building machine learning systems and production software, currently leading Shiny Gen AI from Cambridge, MA. He blends an academic grounding from MIT (MEng in CS, AI concentration) with hands-on roles at Amazon and Lightmatter, shipping ML-focused infrastructure and inference software. His background spans end-to-end ML—from designing CNNs and deploying models on embedded devices to contributing backend code for high-energy physics data processing in the widely used CMS Offline Software. As a former product manager and researcher, he bridges product requirements and research rigor to move prototypes into reliable products. Notably, he implemented low-level signal-processing models in C for medical devices and has merged code touching core experimental validation pipelines, signaling comfort with both high-stakes systems and large collaborative codebases. He’s driven by a philosophy-informed perspective on technology’s role in shaping equitable futures, bringing technical depth and principled judgment to entrepreneurial ventures.
