Selected work

ProjectWhat it is
PLXY AI Call CenterThis platform — an AI callbot between the Cambodia Telco SIP trunk and a 3CX agent pool, with a visual scenario studio, campaigns, live monitoring and a four-axis authorization model.
KNetraHubA documentation-first platform whose style this site follows — including its in-browser AI assistant, which inspired the one you can open in the corner of this page.

How this project is built

  • Decisions are written down. Every consequential choice is an Architecture Decision Record — the reasoning survives the code that implemented it.
  • Documentation is part of the system. This site is built from the same docs/ directory engineers read in the repository, not a marketing copy of it.
  • The brand is the product. The Voice Graph mark — a speech waveform whose peaks are flow nodes — is the call and the scenario builder in one shape, anchored on dodgerblue #1e90ff.
