Greg D is a Staff Software Engineer in San Francisco with 17 years of experience building full-stack products and shaping performance-driven architecture. He has co-founded and led startups, shipped infrastructure and growth features at large companies like Facebook, and helped deliver research-science platforms at the Chan Zuckerberg Initiative. At Flux he focuses on end-to-end performance, app architecture, and growth systems, and he recently returned to steer those efforts while also running a startup project and hobby apps like treedecisions.app. Greg played a hands-on role in the BlockFi wind-down as a board member, helping distribute $1.6B to creditors across 100+ countries—an uncommon blend of technical and operational crisis experience. His background spans qPCR/metagenomics for real-world services, product analytics, circuit simulation, and pricing/AB-testing systems, reflecting both hardware and software fluency. Curious and interdisciplinary, he pairs an MSc in Psychology with deep product and engineering chops to turn complex problems into pragmatic, production-ready solutions.
