dynamic web-app development
design, coding and hosting
of node.js applications
  acd (Alan Craig Dunn) is among the most experienced web-developers around, having worked in information technology (it) for over 30 years and on the web since '95.
  Learning through dozens of projects large and small, using ASP, dotNet, PHP, Windows and Linux, Craig now designs, codes and hosts web-applications using node.js.

Web Applications

  Compared with a static website which simply displays text and graphics, a web-application is a dynamic program with many business or technical functions, fetching, modifying and storing data on its web-servers.
  A web-app becomes a Progressive Web App (PWA) when it is packaged, installed on-device and runs like a native app, enhancing functionality and the relationship between the app and its users.
  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 truly powerful combination of on-line and on-device functionality.


  HeadsUp.social is a social-media site with private messenger and video-calling capability.
  It's built on the principles on humane technology and thereby 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 end-to-end-encrypted messages to be sent over the server.
  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.

Social Media Networking

  acdit has done a lot of work in the social media space, seeking to transcend the Facebook and Twitter era and re-imagine online social life as something positively useful and rewarding. We've developed an alternative to these bad-boys, we've developed completely private encrypted messaging and webRTC-based peer-to-peer video chat.
  Craig has completed the "Fundamentals" course at the Center For Humane Technology and participates actively in the humane-tech community.
