Senior🎓
Top SchoolJeffrey Brown is a technology advisor and software leader with 11 years of experience applying data science, security and DevOps to large public-sector and research systems; since 2024 he advises the director of Colombia’s tax authority (DIAN) on cybersecurity, legacy-system remediation and automated ML/data pipelines. Previously CTO of the Observatorio Fiscal, he built an open-source tax microsimulation and led engineering, data and economic analysis for public-policy forecasting. A longtime Haskell practitioner and open-source maintainer, he authors Hode (a higher-order data editor and hypergraph database), contributed to TidalCycles, and designs semantic knowledge tools that make narrative text as queriable as structured data. He blends rigorous academic training in economics and mathematics with practical experience across government, non-profit and startup environments, and even co-founded a regulated crypto trading firm—an effort he describes as a valuable regulatory and operational lesson.
