A little digital me.

A small digital me. The real one writes Python.

My usual ingredients

Python / Django / PostgreSQL / A little curiosity ✳

01 / Selected work

Under the hood.

Real problems. Considered solutions.
A few things I’ve helped move forward.

Kraken / Engineering notes01
1.43 TB

Less storage. More breathing room.

PostgreSQL, with room to grow
Kraken Technologies2025 — Present

Big systems.
Meaningful improvements.

Working on Link, the backend for electricity settlement. Making large datasets easier to navigate, preventing invalid updates, and giving a busy database some breathing room.

  • Python
  • Django
  • PostgreSQL
A closer look
  • Removed a timeout on a 26-million-record view with lazy pagination and database indexes.
  • Reclaimed 1.43 TB of PostgreSQL storage.
  • Added validation to block approximately 483,000 invalid updates per month.
  • Worked on multi-tenant SSO using OIDC, Okta, and django-allauth.

Work delivered as part of the Kraken engineering team.

CoLab Exeter2023 — 2024

Better tools.
For people helping people.

Led a team of six building a mental-health system for an Exeter charity, from Django development to a cloud migration with zero downtime.

  • Django
  • Google Cloud
  • DigitalOcean
A closer look

Built and deployed the application on Google Cloud, then migrated it to DigitalOcean without interrupting the service. A project that brought together technical delivery, team leadership, and a real community need.

Manchester City FCSummer 2023

A new angle
on the beautiful game.

Built F-Vision, an internal 3D tool using Manchester City’s data. Python meets Three.js, with the final presentation at the Etihad Stadium.

  • Python
  • Three.js
  • Data visualisation
A closer look

Turned club data into an interactive 3D experience and presented the project to a panel including Manchester City’s Head of Technology.

An internal club project; source code and club data are not public.

02 / A bit about me

Curious by nature.
Engineer by trade.

I’m a backend software engineer based in London, with an MSci in Computer Science from the University of Exeter.

My work spans energy, AI-powered VR, community software, and football. The common thread: understanding a problem properly and building something useful.

Outside the code? Football, motorsport, gaming, and figuring out what to cook next.

Good code.
