Who I Am

The Analyst

I specialise in taking raw, often messy datasets and making them speak clearly. My work covers the full pipeline — from data cleaning and exploration to modelling and visual communication.

The Problem Solver

Whether it's building an executive dashboard, segmenting customers, or training a fraud detection model, I focus on outputs that are technically sound and genuinely useful to the people who rely on them.

The Learner

I'm currently deepening my expertise in machine learning and data science, with the goal of building predictive systems that scale. I thrive in environments where curiosity is valued and data is taken seriously.

Numbers without context are noise — but with the right framing, they become the clearest language in any room. That gap between raw data and confident decision-making is exactly where I want to operate. — Timothy Maina
