What you are building
The core problem, expected build, and operating context for this challenge.
Cross-reference public tender awards against GLEIF API entity records to verify supplier incorporation dates. Alert on recently formed entities winning large contracts without verified beneficial ownership data.
Procurement audit analyst
Extract winning supplier identifiers and contract award amounts from OCDS tender releases.
Retrieve legal entity metadata via synthetic GLEIF Golden Copy records to calculate entity operational age.
Check BODS records to verify the presence of declared natural person ultimate beneficial owners.
Generate an audit alert for high-value tenders awarded to recently incorporated entities lacking UBOs.
Dashboard showing tender awards ranked by shell company risk score, with drill-down views into corporate lineage.
Utilize mock OCDS awards and local JSON mocks of GLEIF API entity responses and BODS ownership records. Starter examples below are synthetic. They are not downloaded records.
GLEIF API Uses GLEIF API data model concepts including LEI reference records and entity status flags.
dspy, fastapi, pandas. Optimizes heuristic scoring and narrative explanation pipelines for evaluating complex shell company attributes. Hosted or local model capable of evaluating multi-factor risk profiles and synthesizing structured summaries.
Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.
Calculates company age at time of tender award using GLEIF incorporation date fields.
Flags contracts awarded to entities incorporated less than ninety days before tender closing.
Verifies presence of valid ultimate beneficial owners in BODS records.
Outputs an audit case dossier containing actionable findings.
