Motion on the surface. Calculation underneath.

gridcomet is a software studio: web, mobile, AI and automation. From Türkiye, in three languages.

Halley's comet: observed in 1682, its return calculated in 1705, back in 1758.

In 1758 the comet Halley had calculated came back right on time. The name comes from there: the grid is the calculation, the comet the motion.

Principles.

Each principle comes with something you can hold.

  • Working system first.

    Not a deck; a clickable preview every week.

    A preview link every week

  • Written scope.

    The price is set before work starts and holds as long as the scope does.

    A quote that sets out scope, timeline and price

  • No invented numbers.

    Sample data is always labelled.

    The label on every sampleConcept projectSample data

  • Code others can take over.

    Open, widespread technology; tied to no one person.

    Documented code another team can maintain

The first month.

A clickable preview at the end of every week.

  1. Before we start

    Written scope.

    A discovery note, then a quote: what gets built, in which week, for how much.

  2. Week 1

    Pages, with real content.

    Services, team and hours; a site that works on the phone.

  3. Week 2

    Booking flow.

    Service, day, time; the whole choice is made on the phone.

  4. Week 3

    Salon panel.

    The booking lands in the calendar, the confirmation goes to the customer.

  5. Week 4

    Reminders and launch prep.

    A reminder the day before; domain and analytics are set up.

A sample timeline, based on the Perçem concept project. Duration depends on scope; the real timeline is in the written quote.

What it is built with.

The visible part on top; the calculation underneath.

  1. Site and app

    Next.js, React, Expo

    Says it is an assistant; hands over to the team when needed.

  3. Automation

    The repetitive work between calendar, CRM and e-invoicing.

  4. Data

    PostgreSQL

    Türkiye, the EU region or your own cloud account.

OwnershipCode, domain and accounts are opened in your name; at hand-over the source code and access are transferred to you.

Where the data goesThe full stack
