web-application development
design, coding and hosting
of node.js web-apps
  This is the internet home of Alan Craig Dunn (acd), where entrepreneurial spirit drives innovative web-app development.
  Drawing on long experience of dozens of projects built using ASP, PHP, Windows and Linux, Craig designs, codes and hosts web-applications using node.js.
  Privacy, security and humanity are primary concerns.

Web Applications

  A static website simply displays text and graphics - it becomes a web-application when it provides tools that assist users in accomplishing specific tasks like communication, storage, sales, and so on.
  A Progressive Web App (PWA) is an enhanced web-app meant to be installed on-device. PWAs run, look and feel like native apps while still being web-based.
  A PWA can be converted to a TWA - Trusted Web Activity and listed in Google Play Store and Microsoft Store.
  Even better, a PWA contained within a native Android app delivers a particularly powerful combination of on-line and on-device functionality.


  HeadsUp.social is a social-media site with private messenger and video-calling capability.
  Guided by principles of humane technology, HeadsUp aspires to deliver a rewarding social experience without being addictive or extractive.
  To protect its integrity, HeadsUp avoids advertising and sponsors so it's run as a non-profit, relying on voluntary contributions from supportive members.


  E2EE is the ultimate end-to-end-encrypted instant messenger with video calls and video messages.
  Ads-free, private and secure, there is no surveillance nor data-collection.
  Private encryption keys enable true end-to-end-encryption of all messages, P2P or server-relayed.
  Messages are stored on the device, not the web.


  th-property.com is about as commercial as it gets ... advertising property for sale or rent in Thailand, it lists real-estate on behalf of estate-agents and features houses, condos and land properties for sale by owner.
  Modified versions of this software are available for marketing of real-estate, cars, or just about anything else.
  Contact to discuss that or any other web-application software we might build for you.
