Services

  1. 1.1

    UX & frontend

    From first sketch to a fast, accessible interface. Sign-ups, checkouts and dashboards that people understand without a manual.

  2. 1.2

    Backend & APIs

    APIs, databases and integrations for products with real users. Payments, logins, notifications and the rest of what simply has to work.

  3. 1.3

    Mobile apps

    Apps for iOS and Android from one codebase, sharing backend and logins with your website. From first prototype to the app stores.

  4. 1.4

    Applied AI

    Models that tag content, make recommendations or pull structured data out of video and documents. Built into the product, with a fallback for when they get it wrong.

  5. 1.5

    Embedded & IoT

    Software for devices: embedded Linux, real-time systems, sensors and gateways. Plus the app or web interface that controls them.

  6. 1.6

    Architecture & operations

    Cloud, containers, CI/CD and monitoring, or the whole technical responsibility for a live platform. The goal is boring releases.

02

Work

$ git log --oneline selected work

  1. feat(ai): tag a whole video library by level, genre and technique, with a model that watches every video

  2. feat(app): one app for iOS, Android and the web, on the same backend as the site

  3. feat(checkout): new checkout across several payment providers, without touching existing subscriptions

  4. feat(sso): one login across two platforms that were never meant to talk to each other

  5. feat(device): control a real-time audio device over the network without adding latency

  6. ci(deploy): move a legacy platform onto Kubernetes, so a release is just a git tag

Process

  1. t0

    Understand

    Before promising anything we read the code, look at the data and talk to the people who use it. Then you get a plan and an honest estimate.

  2. t1

    Build

    Small changes, shipped often. Every week there's something new you can try for yourself.

  3. t2

    Run

    Live, with tests, monitoring and documentation. We stay on and look after it, or hand it over properly.

FAQ

What tech do you work with?

Whatever you already use, first of all. Beyond that, the whole stack: UX and frontend, backend and APIs, mobile apps, databases, cloud and Kubernetes, AI models, and Linux on embedded hardware.

Can you take over an existing system?

Yes, that's often where it starts. Code someone else wrote, a developer who moved on, a platform that has grown in every direction. First we make it stable, then we build on it.

How do you use AI?

Where it actually does a job: tagging and sorting content, recommendations, reading documents. Built into the product, measured, and with a fallback for when the model gets it wrong.

Remote or on site?

Mostly remote, for clients in Sweden and abroad. On site in Norrtälje, Uppland and the Stockholm area when it helps.

Hourly or fixed price?

Both work, and so does a monthly retainer. After a first conversation it's usually clear which fits.
