Chomkar.com

Smallholder farmers in Cambodia lose value not from a lack of listings but from weak coordination — buyer demand, pre-harvest visibility, and trust rarely line up in time. Chomkar.com is a Khmer-first, offline-capable market-access product that models that full loop, with a live Cloudflare edge backend powering a claim-safe AI lesson helper and Khmer voice-to-text. It is my strongest current proof: a real Cambodia problem carried from framing to a deployed build, with strict honesty about what the software actually promises.

Proof
  • Top 2 at Turing Hackathon Cycle 10 (theme: Market Access for Farmers).
  • Live edge backend: Cloudflare Pages Functions (/api/ask, /api/transcribe, /api/health) with API keys held server-side, never on the device.
  • Two-layer claim-safety firewall: a Khmer/English keyword guard blocks price/sale/certification topics before any AI call, then a lesson-scoped prompt escalates anything off-lesson to a human.
DeploymentLive at chomkar.com — Cloudflare Pages + edge Functions (AI helper, Khmer voice). Commerce state still demo/in-memory as the product matures.
