Four booths.
All open today.
A demo floor of shipped software. Every door on this map leads to something running right now. No mockups, no “coming soon”. Walk the floor.
Hall A · doors never close · j/k walks the floor · who built this
B-01ZhangJing
OPENBring-your-own-key LLM translation. Paste your text, pick any provider and model, translate with your API key. Everything runs client-side; the key never leaves your browser. Swap translation and text-to-speech providers on the fly; listen to or download the result.
The proof: real multi-provider LLM integration with zero backend: the whole product is the browser tab.
B-02PeerAuth
OPENA hedge against AI deepfakes: when a voice and a face can be forged, how do you know the person on the phone is real? PeerAuth lets two people set up a shared TOTP secret in person (scan, verify, done), so any future call or video chat can be confirmed with a 6-digit code. No accounts, no server holding your tokens; the whole mechanism lives on the page and in the public source.
The proof: security mechanics done client-side: cryptography as a static page, not a service.
B-03Xuanzang
OPENLearn geography and history by travelling. Follow Xuanzang’s seventh-century journey from Chang’an along the Silk Road on an animated map: step-through journey lessons that draw the route as you go, place quizzes built from researched historical geography, and present-day context at every stop. Fully bilingual, English and 中文.
The proof: content, cartography, and interaction engineering in one shipped learning product.
B-04ClusterMob
OPENA community registry of Hermes agent profiles and profile packs — publish what you have built, browse and search what others have, all backed by a public REST API documented with OpenAPI. Unlike the other booths on this floor, this one is a full production product: frontend, backend, database, and deployment, running at clustermob.com.
The proof: end-to-end product ownership: from schema to serving live traffic.
The engineer behind the floor
I’m Ka Lun “Kal” Sze, a senior software engineer in Calgary. For five years I built the backends behind industrial energy-sector platforms at Avaxia Group: TypeScript and Node services that handled real operational data at scale. Before that: machine-learning infrastructure for retail video analytics.
I work agent-first. An AI agent (Hermes) is my daily implementation partner, and making that partnership productive is a discipline of its own: I engineer the agent’s environment, baking custom container images with the right toolchains preinstalled and gating its actions behind explicit approvals; I author skills and plugins that make the agent measurably more capable; and I upstream the improvements into the agent project itself. ClusterMob (booth B-04) is the community side of the same work: a public registry where people publish and share agent profiles and packs. Everything on this floor shipped this way.
Everything on this floor is real, running, and public. Walk into any booth; the source is the résumé.
