Stop Copy-Pasting Listings by Hand

Manually copying listings from other sites eats hours every week. I build extraction so new listings land in your system automatically.

Stuck With a System Someone Else Abandoned

Previous developer left, and now nobody can touch the system. I take over existing AppSheet apps and keep them running, no rebuild required.

Compliance Documents Scattered Across Files

Government rental programs demand specific paperwork. Upload, track, and report on lease status automatically as your portfolio grows.

One View: Map or Table, Your Choice

See your whole portfolio at a glance, on a map or in a table, whichever way you think about your properties.

No Idea What's Happening in the Field

Yard signs, site visits, listing photos, no one knows the current status. Snap a photo, log it, done. Know where every sign or site stands without driving out to check.
