Data & Knowledge Engineer | Judicial Data and AI Governance Architect | Python Developer

Abidjan, Côte d’Ivoire · LinkedIn · Email

I design governed data, knowledge and decision-support systems that transform heterogeneous datasets and documents into traceable, searchable and actionable knowledge.

Je conçois des plateformes de données, de connaissances et d’aide à la décision qui transforment des sources hétérogènes en informations structurées, traçables, recherchables et exploitables.


Professional profile | Profil professionnel

Judicial administrator, project manager and Data & AI Governance practitioner with 12+ years of experience in Côte d’Ivoire’s justice sector. Current work combines public-sector transformation, data engineering, document intelligence, information retrieval, local AI and scientific evaluation.

Administrateur des services judiciaires, chef de projet et praticien de la gouvernance des données et de l’IA, avec plus de douze années d’expérience dans le secteur de la justice en Côte d’Ivoire. Mes travaux relient transformation publique, data engineering, intelligence documentaire, recherche d’information, IA locale et évaluation scientifique.

Current positions:

  • Deputy Director of Studies and Statistics, Ministry of Justice, Côte d’Ivoire
  • Head of IT and Statistics Services, Court of Cassation of Côte d’Ivoire
  • Justice Coordinator, USAID ProJustice-CI Program
  • Project and Program Manager for data, AI and digital-transformation initiatives
  • PhD-track researcher in Judicial Data Governance, Digital Justice and Responsible AI
  • Le Wagon Data Science & AI graduate, Batch 2149 (2025)

Technology alone does not transform institutions. Governed data, institutional learning and responsible innovation do.

LIAOS — Local Intelligence Platform for Observation, Analysis, Orchestration and Search

Independent, domain-neutral and local-first document intelligence platform. LIAOS combines governed ingestion, SQLite storage, document provenance, citations, lexical retrieval, reliable workflows and local language models.

Key results:

  • 2,276 indexed documents and 143,746 traceable chunks
  • TXT, Markdown, HTML, PDF and DOCX ingestion
  • SimpleSearch and SQLite FTS5/BM25 retrieval engines
  • transactional outbox, idempotency, dead-letter workflows and persistent scheduling
  • governed source registry and secure bounded collection
  • Ollama and LM Studio integration without mandatory cloud dependency
  • reproducible information-retrieval evaluation with Goldsets, Hit@k, Precision@k, Recall@k, MRR and nDCG
  • approximately 396 automated tests

Current milestone: human annotation of the scientific Goldset before the official SimpleSearch and FTS5 baselines.

Modular governance and control framework for AI-assisted projects, knowledge systems and supervised workflows.

  • versioned manifests and JSON Schema validation
  • jdgf command-line interface
  • Knowledge, Advanced RAG, Agent and Workflow contracts
  • security-by-default and human-approval gates
  • optional PostgreSQL, Redis, Neo4j, Qdrant, Ollama and LiteLLM contracts
  • FastAPI control surface, CI hardening and dependency auditing
  • current developer preview: v0.10.1

Doctoral funding intelligence and decision-support platform.

  • opportunity, evidence and application-readiness models
  • deterministic scoring and supervisor matching
  • Streamlit cockpit and FastAPI-compatible interfaces
  • SQLite persistence, Snowflake preparation and cloud deployment workflows
  • mandatory human validation before outreach or application submission

Digital-learning and knowledge-governance prototype for court registries and judicial institutions.

  • structured judicial knowledge corpus and source inventories
  • Streamlit learning prototype
  • governance-state, ownership and validation models
  • documented institutional pilot use cases
