# Mario Marcolongo — Data Quality & Information Retrieval | AI Evaluation & Adversarial Testing | Scientific Fact-Checking & Evidence Synthesis
> Information Retrieval · Evidence Synthesis · AI Evaluation

> My work spans information retrieval, data quality, scientific fact-checking, AI evaluation and research operations. It includes eight years of auditable public-source and structured-data work, a maintained research-participation directory and self-directed model-behavior testing. On 29 July 2026, the Gray Swan Proving Ground profile displayed rank #74 (top 6%) and 113 total breaks. Entropy for Life work covers 80 documented published content contributions: 55 YouTube videos · 4 articles · 21 short-form pieces. Technical delivery is AI-assisted, with personal responsibility for requirements, verification, deployment and maintenance. Current open-source product work includes Notandia (formerly MDPI Filter), a continuing browser and Zotero research-integrity tool.

> **My technical work uses AI-assisted implementation: I define requirements, inspect implementation behavior, test releases, diagnose functional problems, guide iterations, deploy releases and maintain services.**

## Core Competencies
- Information Retrieval & Verification: Primary-source and bibliographic search, claim tracing, source discovery, query refinement, source-quality assessment and cross-source corroboration.
- Data Quality & Provenance: Structured metadata, entity reconciliation, validation rules, documentation, taxonomy design and public-record verification.
- AI Evaluation & Adversarial Testing: Exploratory model-behavior testing, prompt and jailbreak analysis, multi-turn behavior, multimodal inputs, agentic tool-use and indirect prompt injection.
- Scientific Verification & Evidence Synthesis: Primary-source fact-checking, bibliographic research, claim decomposition, evidence screening, source-quality assessment and cross-source corroboration.
- Data Visualization: SVG vector diagrams, Tableau Public, Flourish and open-data publication.
- Evaluation Planning & Reporting: Test planning, evidence capture, reproducibility notes, taxonomy thinking, issue classification, reporting that separates evidence from inference and mitigation-retesting concepts.
- Technical Delivery: Requirements definition, codebase reading and behavior inspection, functional testing, issue diagnosis, deployment and service maintenance.
- AI-Assisted Implementation: Uses coding agents for implementation support while personally defining requirements, inspecting structure and behavior, testing results, guiding revisions, deploying releases and maintaining services.
- Open Science & Structured Data: Wikimedia, Wikidata, FAIRsharing, Zenodo, ENA records, JSON-LD, RDF Turtle/VoID, OpenAPI and MCP interfaces.
- Web & Cloud Delivery: WordPress, HTML/CSS modification, Git/GitHub, JSON, REST APIs, AWS Lambda, Cloudflare Pages, DNS/SSL and CI/CD maintenance.
- Languages: Italian — native. English — C1 overall (EF SET 68/100), with advanced technical reading and professional/technical writing.
