About Me

Researcher. Analyst.
Problem Solver.

I'm a data scientist from Dar es Salaam, Tanzania, with an MSc in Data Science (First Class) from Chandigarh University, India. My work sits at the intersection of machine learning research and real-world data analysis.

I've published research on deep learning for wireless networks, built computer vision systems for medical diagnostics, and delivered data insights across telecoms, consulting, and engineering sectors.

Currently exploring PhD opportunities in machine learning and AI while working as a data and systems consultant in Dar es Salaam.
