Track record

Our work since 2022, grouped by type. We describe internships, research, and competitions exactly as they were.

Client work

Home page of the Tjampaka Ornamen website: CNC plasma cutting of metal plates Plate cutting estimator on the Tjampaka Ornamen website

Tjampaka Ornamen (Tjampaka Cutting)

A metal plate cutting workshop with a CNC plasma machine in Parakan Muncang, on the road between Bandung and Garut

A business website with four pages: home, a catalogue of materials and patterns, a cost estimator, and location and contact details.

  • A plate cutting estimator. It calculates the area, the estimated weight of the plate, the length of the cutting path, and the recommended vehicle for transport. Customers can also upload CAD design files (DXF, SVG, G-Code, PLT) and see the drawing straight away in the browser.
  • A catalogue of materials and ornamental patterns, and an archive of finished work.
  • A WhatsApp button that opens a pre-filled order message, so customers only need to add the size and material.
  • We also built an inventory system to record incoming and outgoing stock.

Proofs of concept for government

A proof of concept is a working example that shows an idea can work. We have built and tested both of the following ourselves, but no government agency uses them yet.

  • AI document assistant: answers questions from the content of an agency's PDFs and shows the page each answer comes from. See Services
  • JombangSatu: a prototype (early example) of a public service portal. See Products
