Nuqta · نقطة

An Arabic-first Flutter app for children aged 5–12: short learning quests with Saqr the falcon, screen-time pauses that ask one question before more video or games, and controls that stay with the parents. Android beta for families in and around Nazareth.

Sales agentlocal-rules · demo catalog

Scripted rules, demo catalog, no model. The real agent adds a language model behind these same gates.

  2. Shape

    Choose the smallest architecture that can deliver the whole outcome.

  3. Build

    Ship in visible slices with tests, observability, and clear review points.

  4. Operate

    Deploy, document, measure, and make the handoff usable.
