Governance Intelligence & Network Analysis Platform (Knowledge Graph). Architected and built a multi-tenant, multi-region knowledge graph platform connecting public entities (people, organizations, positions, projects) through evidence-backed relationships. Designed a governance model requiring every data point to be sourced, with a legal review workflow before findings go live. Built graph traversal API (recursive queries, cycle-safe, depth-capped) and row-level security for tenant data isolation. Solo-built: database architecture, backend API (Laravel), and multi-tenant security layer.
