Senior Data / Full-Stack Engineer

We’re building a financial intelligence platform focused on corporate distress, ownership networks, litigation, insolvency, and enforcement, with an initial focus on Hong Kong, Cayman, and BVI. We need an experienced engineer to build a reliable, auditable data and relationship engine, not just a dashboard or chatbot. The initial PoC (2–4 weeks) includes architecture, temporal data modeling, data ingestion, entity resolution, evidence-backed relationship graphs, historical timelines, source-linked research output, tests, and deployment documentation. Experience with production pipelines, entity resolution, knowledge graphs, temporal data, and financial/legal records is important. Relationships must be source-backed, and the system must distinguish facts from allegations, prevent false merges, and support historical accuracy. Please describe a relevant system you built, your approach to evidence tracking and historical relationships, what you would deliver in 2–4 weeks, and your rate, availability, and code sample or case study.
