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).
  • 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).
