Hi, I'm Jumma Mohammad Teli 👋

MLOps Engineer & Senior Data Analyst
Turning messy data into production-grade decisions — from SQL pipelines and Power BI dashboards to FastAPI model serving, drift detection, and Kubernetes deployments.


🚀 About Me

Data professional with 9+ years of experience, now building end-to-end MLOps systems. I bridge analytics and engineering: extracting insight with SQL and Power BI, then shipping models into production with FastAPI, MLflow, Airflow, and Kubernetes.

  • 🏢 Currently: Data Analyst @ UBS, London (Oct 2024 – Present)
  • 💼 Previously: Data Analyst @ IT Skills, London (Oct 2023 – Oct 2024)
  • 🎓 Education: MSc Computer Science, Queen Mary University of London (2023–24)
  • 🎯 Focus: ML/AI Engineer & Senior Data Analyst roles in the UK
