qqPOS

In production

qqPOS home page: point of sale for Southeast Asian shops and kitchens.

Run your whole shop from one place.

The till, kitchen screen, stock book, and daily report for shops, cafés, and restaurants across Southeast Asia. It works in Burmese and English, keeps taking orders when the connection drops, and accepts the cash, cards, and QR wallets customers already carry.

Built for — Grocery and retail, phone and electronics, cafés and restaurants

  • Checkout

    Scan, tap, or search, then take cash, card, or QR in a couple of taps — with multiple carts held and resumed.

  • Tables and kitchen

    Orders reach the kitchen screen the moment they are placed, notes and all, behind a live table map.

  • Stock and reports

    Branch-level sales, profit, and staff numbers, IMEI tracking per unit, and an owner-only audit log.

PoPoTalk

In production

PoPoTalk home page: AI conversation practice with scored scenarios.

Master the art of conversation.

A practice gym for conversation. You role-play realistic scenarios with AI characters who respond like people, then get scored on tone, engagement, empathy, and timing — with none of the cost of getting it wrong in the room.

Built for — Dating, interviews, networking, negotiation, everyday conversation

  • Scenario library

    Realistic situations with real stakes, climbing from a warm opener to the full conversation gauntlet.

  • Live coaching

    A coach watches the exchange and scores every message, with an affinity meter showing how close the conversation is to opening up.

  • Progress

    XP, tiers, and achievements that turn practice into a weekly habit rather than a novelty.

qqdraw

In production

qqdraw home page: a shared mood board with live cursors.

Pin it once. Everyone sees it.

References, screenshots, and scribbles on one canvas, with everybody's cursor in the room. A mood board people use at the same time rather than a folder they take turns in — built on a fork of Excalidraw, with the scenes kept in the cloud.

Built for — Design teams, studios, and clients reviewing work together

A fork of Excalidraw

  • Live cursors

    Every pointer carries a name and a colour derived from its id, and presence is keyed by connection — two tabs are two cursors, and a closed tab leaves without taking the person with it.

  • No save button

    Elements merge into the room and flush to the cloud on a short debounce. Conflicts resolve by version and nonce, and deletions stay as tombstones.

  • Open by link

    A public board is the invitation: guests get a name and a colour and draw immediately, no account. Switch it to private and only invited members get in.
