      The most fruitful pull requests are the ones which remove more lines of code than they add, according to Pimm. He is just as comfortable designing systems from a bird's eye view, as he is optimising low level code.

  • Tech

    We utilise a variety of technologies, including TypeScript, Node.js, GraphQL, and PostgreSQL. These allow us to swiftly whip up functional prototypes, and iterate them into future-proof, scalable products.

    React is our UI framework of choice for webapps. As early adopters we have an intimate understanding of its workings and are deeply familiar with it's ecosystem.

    By utilising serverless architectures, containerisation, and edge computing where appropriate, we optimse solutions for efficiency and robustness.

    Don't delude yourself with fake 2FA

    Two-Factor Authentication enhances security by adding a second distinct layer of authentication, mitigating the risk of stolen passwords. However, some services inaccurately label their security as 2FA when in reality they utilise only a single factor, misleadingly offering a false sense of heightened security.
