Hello, I'm Alex Bristow.

Projects

Most of my professional work is confidential, so these are the projects where I can show how I think, the trade-offs I made, and what I shipped.

• nxk

  2026 · Open source skill

  nxk gives coding agents a crowd of simulated people to ask about their work. It shows who answers differently, so they can decide what to ask or change next.

• PersonaGen

  2025 · Personal project

  An API for fast, repeatable synthetic people. I made roughly 94,000 LLM calls to build the probability data, then took the LLM out of the request.

• mdplane

  2026 · Open source product

  A shared markdown worklog for people and coding agents. Tasks, claims and blockers stay in one file that everyone can read.

• Draftastic

  2023 · Personal project

  A live team drafting app I built after watching a tournament spend an hour assigning 100 people to 20 teams over a call and a spreadsheet.

• Professions.gg

  Summer 2021 · Personal project

  A Classic WoW tool I built to put recipe skill-up odds and live auction house prices together. It was the first personal project I actually shipped.

• Dealio

  2017 · Personal project

  A promotion management portal I built while working as a supermarket buyer. The spreadsheet problem was mine, and building a way out of it got me into software engineering.

Experience

Over the past 8 years I've built workflow tools, operational software, and customer-facing products used by thousands of employees and millions of customers every day.

1. NBCUniversal

   2023 to now · Senior Developer

   Own front end for an enterprise GenAI platform, the first GenAI product in the business to reach production. Built the Alerting Gateway portal used by hundreds of engineers and ops staff to keep Peacock, NOW, SkyShowtime and Showmax streaming.

2. Ocado

   2022 to 2023 · Senior Software Engineer

   Led the platform-wide migration from Universal Analytics to GA4 on behalf of ~100 engineers, and delivered the Recipes feature end to end across 10+ international retailers.

3. Sky

   2018 to 2022 · Front End Developer → Senior Front End Developer

   Built large-scale data visualisation tools for monitoring viewership and streaming health, and a React boilerplate adopted by dozens of teams.

4. SPAR UK

   2014 to 2018 · Graduate Buyer → Trading Manager

   Commercial responsibility for a ~£120m retail category. Started building internal tools to improve buying workflows, which led to a career change into software engineering.
