David Hao is a pragmatic software engineer and repeat early-stage operator based in San Francisco with nine years of hands-on experience spanning startups and cloud services. He has co-founded Roomadillo, brokering half a million in medium-term rentals while still a student, and later joined Lilac Labs and now LedgerUp in product-focused engineering roles. His background includes an AWS FSx internship and technical project leadership at Cisco, where he proposed practical computer-vision and Wi‑Fi heatmapping solutions to drive business insights. Trained in computer science and mathematics at UNC with study time in Singapore, he blends analytical rigor with a knack for shipping customer-facing systems and turning side projects into real revenue. Unusually for someone early in their career, he pairs entrepreneurial instincts with cloud systems experience across both infrastructure and marketplace domains.
