About Me

I'm a software engineer that specializes in APIs, journey planning algoritms and highly available services.

Normally I work as a lead developer but I still like to get my hands dirty with node.js (preferably TypeScript), MySQL and whatever else comes my way.

I tend to pick up new technology in my spare time like Scala, Rust or even a bit of Ansible / DevOps.

I'm an advocat of Agile development and usually set my teams up in a Scrum environment or Kanban if it suites the task better.

Profile Pic


Name: Linus Norton Likes: Programming, algorithms, beer with friends Dislikes: Spaghetti (code and food), apathy I have a blog.

I founded Planar Network, to bring blockchain technology to public transport. As part of my work at Planar Network, I developed a best in class journey planner for UK rail and created a whole set of tools to process industry data.

Before founding Planar Network, I was CTO at Assertis where I led a merry band of men (and women) in a quest to make rail travel and tickets a more bareable experience. My areas of expertise are software architecture, software development, microservices, continuous integration, Agile (mostly Scrum), TDD and leadership.

I have various open source projects on GitHub. I'm crazy enough to have built a journey planner using the Connection Scan Algorithm, Transfer Patterns and a few other bits of graph theory. I've released quite a few open source Node.js projects, including a massively multiplayer version of game of life using websites and a tool to help find developers.

Occasionally I enjoy speaking at conferences - I spoke at the inaugral London TypeScript meet up, HackTrain and at the London PHP Conference on the unconference track.

My real passion is working with a great team to deliver challenging products. I love reading, particularly about programming, learning, leadership and motivation.
