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

  A skill that lets a coding agent ask a crowd of simulated people about a decision while it works. It shows who answers differently, and the agent keeps asking until it knows what to change.

• PersonaGen

  2025–26 · Personal project

  An API of synthetic people for the UK and the US, built on published statistics. Each has 237 facts that fit together, and a crowd of them looks like the country.

• mdplane

  2025–26 · Open source product

  A shared worklog that lets coding agents on different tools and machines hand work to each other, such as Claude Code on a laptop and Codex in CI. Any agent joins through one link, with no account or install.

• Draftastic

  2023–26 · Personal project

  Live team picking and tournaments for clubs, schools and events. The room watches on a big screen while everyone follows their own part on their phone, with nothing to install.

• Professions.gg

  2021–22 · Personal project

  A World of Warcraft Classic tool that showed players which recipes were worth crafting to level a profession, using live auction house prices. It was my first shipped side project, and about 20,000 people used it on launch day.

• Dealio

  2017–18 · Personal project

  A promotions portal for suppliers, buyers and wholesalers, built while I was a supermarket buyer to replace the process I worked in. It's how I got into engineering.

Experience

For 8 years I've built software that teams depend on to run streaming operations, respond to incidents and manage cloud costs, and features for grocery retailers serving millions of customers a week.

1. Sky · NBCUniversal

   2023 to now · Senior Developer

   Design and build the internal tools NBCUniversal's global operations teams use to keep Peacock and its other streaming services running, from a GenAI assistant for live events like the Olympics to alerting, cloud costs and a developer platform.

2. Ocado Group

   2022 to 2023 · Senior Software Engineer

   Built the Recipes feature for the 10+ grocery retailers on the Ocado Smart Platform, which serve millions of customers a week, and led the platform's move to GA4.

3. Sky

   2018 to 2022 · Front End Developer, then Senior Front End Developer

   Built the tools Sky's executives and teams used to follow viewing and streaming health through the launches of Peacock, SkyShowtime and Showmax.

4. SPAR UK

   2014 to 2018 · Graduate Buyer, then Trading Manager

   Managed a grocery category worth about £120m. Taught myself to code in the evenings to build Dealio, a promotions portal to replace the process I worked in, which led to my move into software.
