I build evaluation-grounded AI systems for African and low-resource contexts.

My work combines:

  • Responsible AI and AI evaluation
  • Retrieval-grounded assistants and agent workflows
  • Low-resource speech and language systems
  • Dataset curation, validation, and benchmarking
  • Human escalation, uncertainty handling, and real-world failure analysis
