Hi, I'm Victor Collins Oppon

Data Scientist & ML Engineer | FCCA | MBA Finance | MSc Data Science (2026)

Building Production ML Systems that Drive Real Business Results

Portfolio LinkedIn Email


About Me

I'm a Data Scientist & ML Engineer with 15+ years of analytical leadership, uniquely positioned at the intersection of advanced machine learning and financial expertise. With a rare combination of Chartered Accountancy (FCCA) and cutting-edge ML/AI capabilities, I architect production-grade ML systems that deliver measurable, transformative business impact.

I specialize in transforming complex business challenges into scalable, production-ready ML solutions across Finance & Risk Analytics, Healthcare AI, Retail Intelligence, and Enterprise Automation — delivering end-to-end ML pipelines from strategic concept to deployed, monitored production systems.

What Sets Me Apart

  • Rare Dual Expertise: FCCA Chartered Accountancy + 15+ years business leadership + cutting-edge ML/AI. I don't just build models — I understand the business context, ROI implications, and strategic value that makes them impactful.
  • Full-Stack ML Expertise: From deep learning (PyTorch, TensorFlow) to gradient boosting (XGBoost, LightGBM, CatBoost) to NLP transformers (BERT, GPT) — I select and implement the right technique for each business problem.
  • Production-First Mindset: Every project includes interactive Streamlit dashboards, FastAPI endpoints, Docker deployment, and comprehensive documentation.
  • Explainable AI Champion: SHAP, LIME, Grad-CAM, and feature importance analysis in every project for interpretability, regulatory compliance, and stakeholder trust.
  • Multi-Domain Versatility: Proven success across Finance, Healthcare, Retail, Insurance, NLP, and Computer Vision.
