I love building things that matter.
Senior software engineer with 12 years of industry experience across multiple disciplines, including leadership and IC roles. Systems thinking, hard problem solving and products that people use daily are what excite me.
Senior software engineer · London · alex.connolly.cloud
Linnworks · 12 years · e-commerce operations software, in London
- 2026–now · Senior Software Engineer, Software Architect
Moving changes between products, and working out which product owns which data for each customer. - 2024–2026 · Senior Software Engineer, Carrier Solutions
Rewrote the carrier integration layer so a change stopped meaning the same edit in twenty places. - 2022–2024 · Engineering Team Lead, Analytics
Started the analytics product and the team around it, and built the ETL underneath it. - 2017–2022 · Software Engineer, Order Management
Batch inventory tracking, and an open-orders screen built to cope with a lot of changes at once. - 2014–2017 · Software Engineer, Platform
The developer ecosystem and app store — payments, billing, and third-party integrations.
Full stack, with the back end as home.
- Day to day — C# and .NET on the server, TypeScript and React in front of it.
- Data — Postgres, MSSQL and Redis: schemas, migrations, and the occasional query plan.
- Distributed — Service Bus, Kafka and SQS. Queues, retries, and making things idempotent.
- Cloud — AWS by preference, Azure by experience. Docker and GitHub Actions around both.
- Lately — Agentic tooling, RAG, and running small open models locally.
Mostly I believe in picking the right tool for the job.
- smarty · C# — a personal assistant on your own machine, on whatever model you point it at. It works in the background, and takes plugins and any MCP server you give it.
- agent-skills · Python — skills for coding agents. Each one packages a working toolkit and the method for using it, not just a prompt.
- interchange · TypeScript — a yard, two trucks, and a district you slowly end up owning. Playable at interchange.connolly.cloud.
- miniweather · TypeScript — cute, mini world weather for wherever you happen to be.
Mostly evenings and weekends. All of it is on GitHub.

This repo is also the source of that page
A React and Vite site built to the Barbican Identity Guidelines (North, 2007) — one typeface, ranged left, sentence case, leading tighter than default — with the four forms of the four-colour process, circle, square, half-circle and diamond, as the mark, one per section. The full design rationale, sourced and quoted, is in PLAN.md.
