4D STUDIO

Services

Two lines of work, one method.

Below is what we actually do and what you get at the end. If you need something that is not listed, ask — it is probably a variant of something that is.

§01

Software development

We take a project from specification to delivery, or join an existing team at a particular stage.

  • 01.1

    Mobile applications

    iOS and Android. React Native where one codebase is enough, native where performance or hardware access requires it.

    • Architecture and screen specification
    • Implementation and API integration
    • App Store and Google Play submission
    • Support after release
  • 01.2

    Web applications and sites

    Marketing sites, portals, internal tools and admin panels. Accessibility and load speed are part of the definition of done.

    • Design system and components
    • Implementation in Next.js / TypeScript
    • Database and API
    • Deployment and domain setup
  • 01.3

    Desktop applications

    Windows, macOS and Linux. For tools that run offline, reach the file system, or have to stay fast on large data.

    • Requirements analysis and technology choice
    • Implementation and installers
    • Automatic updates
    • End-user documentation
  • 01.4

    WordPress websites

    Business and marketing websites, plus custom plugins for functionality that off-the-shelf solutions do not provide.

    • Structure and custom design
    • Theme development or adaptation
    • Custom plugins and integrations
    • Optimisation, security and maintenance
§02

Mathematics education

Teaching is organised around understanding the procedure. A problem counts as solved once the student can explain why each step works.

  • 02.1

    Competition preparation

    For primary and secondary school students. We work by problem type, using papers from municipal, district and national competitions.

    • Initial assessment
    • Plan by topic and by week
    • Problems from past competitions
    • Regular feedback
  • 02.2

    Entrance and final exam preparation

    Systematic coverage of the syllabus in an order that builds on itself, with timed mock tests throughout.

    • Full syllabus coverage to plan
    • Work on past exam papers
    • Mock tests and error analysis
    • Progress report
  • 02.3

    One-to-one and small group lessons

    One to one, or in groups of up to four. The pace adapts to the student, but the goal for each week is set in advance.

    • Programme adapted to the student
    • A measurable goal each week
    • Materials for independent work
    • COMING SOON — In person and online
§03

How we start

The same order for a project and for teaching.

  1. 01

    Conversation

    A short conversation about what you need and by when.

  2. 02

    Estimate

    A written estimate of scope, price and dates. No obligation.

  3. 03

    Work

    We work in agreed cycles, with regular progress reviews.

  4. 04

    Handover

    Delivery with documentation, or a closing assessment.
