AI/ML Engineer

Algorythme Nov 2025 – Present
  • Designed a multi-tenant EdTech content-generation platform with FastAPI, Supabase, and Gemini, reducing curriculum-aligned lesson and assessment production from weeks to minutes.
  • Architected a two-tier RAG pipeline using 400-character semantic child vectors in Pinecone hydrated from 2,500-character Redis parent payloads, anchoring responses to verified material and reducing hallucination.
  • Engineered a longitudinal AI profiling engine that analyses chat transcripts and updates Redis profiles to adapt LLM pedagogy across sessions.
  • Hardened pipelines against adversarial input with PBKDF2-HMAC authentication, JWT validation, Pydantic regex sanitisation, and Redis rate limiting.

AI/ML Engineer

African Institute for Artificial Intelligence (AI4AI) Feb 2025 – Oct 2025
  • Deployed a secure multi-tenant RAG Knowledge Assistant with LangChain, Pinecone, AWS S3, and PostgreSQL, enforcing RBAC/ABAC controls with zero cross-tenant data leakage.
  • Built an AI timetable scheduler for an NP-hard academic scheduling problem; greedy initialisation cut conflict rates by more than 70%, while conflict-directed mutation converged to zero-conflict schedules.
  • Set up containerised deployment infrastructure with Docker, Prometheus/Grafana monitoring, and incident runbooks for production observability.
  • Designed a mentorship-matching recommender across structured and unstructured profile attributes.

AI Engineer

Mensah Philosophic Circle Jan 2025 – Aug 2025
  • Co-developed Hey Nova AI, an Azure OpenAI educational agent with live internet access, Azure AI Search, Redis, automated summarisation, and question generation.
  • Designed a YOLOv8/InceptionResNet premises-security prototype that achieved more than 90% detection accuracy, with FAISS-backed audit-trail retrieval.

Machine Learning Engineer Intern

Zummit Africa Jan 2024 – Jun 2024
  • Built a zero-shot content-moderation proof of concept with Hugging Face BERT-family models, validating zero-shot classification as a scalable, label-free alternative to supervised pipelines.
  • Developed retraining pipelines and evaluation scripts using accuracy, precision, recall, and F1-score.
