Estate agency SaaS for duHome

Provide a customisable website for estate agencies.


  • Fuzzy-logic search, gradually widening search criteria scope when not enough matching results are found, i.e. for every non-matching input criteria a corresponding potentially acceptable criteria would be used instead such as 1 bathroom instead of 2, with these criteria being colour-coded (match versus near-match) for easier identification by the user.
  • Comprehensive type-ahead search using multiple sources of data (names, telephones, locations, emails, prices), removing need for time consuming paging of adminstrative list views to find relevent records.
  • Use of geohash indexes for high-performance geospatial property search.
  • Use of deferred slideshow loading to improve performance and usability (almost unheard of at the time, most solutions simply advancing to to half-downloaded images on a timer, or attempting to download all upon page load despite potentially not subsequently showing them).


  • Customer-facing functionality including geographic search and display of properties with mapping and slideshow
  • Agent functionalities including search, management of properties
  • Agency-owner functionality including customisation and configuration of website, and management of agents
  • Support for multiple agency locations per site, and agents per-agency

  • Checkin system to indicate daily member presence
  • Per-resource (e.g. bedroom) availability calendar

API Gateway for Pixelpipe

An API gateway server accepting media uploads from clients using a wide variety of supported APIs, and re-broadcast them to well over 50 different service providers.


  • Deferred batching to accept multiple uploads over a configurable timeframe, and then re-broadcast them together as an album or single blog post after no more items had arrived (instead of individually upon arrival).
  • Utilisation of special 'routing' tags, allowing uploaded media to be dispatched to specific accounts or groups of accounts simply using a tag, thus avoiding the need for specific client routing UI, and instead using a client's native tagging UI.


  • Prioritised image processing queue with service provider connection constraints
  • Service provider error aggregation and reporting to quicly idenitfy and prioritise API issue resolution with destination service providers
  • Support for multitudinous client upload APIs including metaweblog and Flickr, which with DNS spoofing enabled official clients to be used with the server
  • Bespoke upload applications and Plug-ins including iPhone, Aperture, Windows Live Gallery and integration with Nokia share
  • Support for hosting uploads directly on the service, including views for user streams, albums and individual photos
