Juha Ristolainen

CTO at the Innovation Hub for Daimler Fleetboard.

I like working on cross-platform mobile technologies (Xamarin, React Native, NativeScript, etc. ) as well as microservices backends (.Net, Go, Scala, Node.js). I like working with serverless (FaaS) on Azure, AWS and GCP. I’m a bit of a Restafarian as well but love GraphQL.

Background I have been working as an interim CTO in a Lean Service Creation agency here in London for the past year and one of the most interesting pieces of work that has come across my desk was to do a full replatforming for a startup in the event space. They gave me free reign on the technology side to build a futureproof and scalable platform for them. They had grown enough to start having issues with their WordPress-only site and wanted to build a platform to take them to the next level. [Read More]

So long London

We're moving to Berlin

We are saying goodbye to Brexit Britain in May after 4 amazing years here. Things we love about London: Tech Scene. Undoubtedly the best place to be in tech outside of Silicon Valley.

Things we do not like so much: Congestion. [Read More]


Visual Studio Code Extension

I recently discovered a service called Code::Stats. It’s a simple service that tracks how many keystokes you do while editing your source files using plugins to your favourite editors. Each keystore measures as 1 XP or Experience Point. There were already a few plugins available for Atom, Sublime Text 3 and IntelliJ editors but none for my main editor Visual Studio Code. Code::Stats has a simple API so I created an extension to Visual Studio Code for it. [Read More]

MS Accelerator London Cohort 7

Taking part in the judging panel

I was kindly invited to take part in one of the judging panels for cohort 7 in the Microsoft Accelerator in London. Thank you for an interesting day. I was happily surprised at the level of the applicant startups. Most of them were of high quality. The focus was clearly in more established startups rather than very early stage. Each venture had an established team and product already and were looking for Microsoft’s help in scaling/accelerating their business. [Read More]
