Data Analyst · London · Turning complexity into clarity

I got into data because the questions were too good to ignore.

There's always a gap between the data an organisation holds and the decisions it actually makes well. I've spent my career trying to close that gap — through better pipelines, cleaner models, and dashboards that people actually open.

My work spans the full analytics stack: writing complex SQL to extract and model data, using Python for analysis and automation, and building Power BI dashboards that translate numbers into action. I care about the output being useful, not just technically correct.

Outside of work I've been building Hoodly — a personal project that scores 150+ London neighbourhoods across 20 factors, and a London Location Finder that uses Dijkstra's algorithm on the TfL network to find the best place to live given where multiple people need to commute. Both projects reflect what I care about: using data to answer questions that genuinely matter to people.

What I believe about data

🎯

Outcomes over process

Good analysis creates better decisions. I care as much about how findings land with stakeholders as I do about the methodology — the deliverable matters, but the outcome it drives matters more.

🔎

Question the data first

Before building anything, I ask whether the data is actually telling us what we think it is. Garbage in, garbage out — always.

🗣️

Clarity over complexity

The most impressive thing a dashboard can do is make a complicated thing obvious. Simplicity is the skill.

🏗️

Build things that last

Pipelines, models and dashboards that don't break when the data changes. Maintainability is a feature.
