Real Estate · Approach
every property,one front door
Listings, tours, residents, and the devices in the building, on one system instead of a phone tree and five logins.
Illustration: a schematic map with five sample price pins. Each pin activates in turn, the listing card below updates to match, and a tour slot is booked.
01 · The hard part
Where property teams lose time
The listing is the easy part. Everything after the first inquiry is where the hours go.
Listings out of date everywhere
The same property shows different prices and statuses on every site that syndicates it.
Tours booked by phone tag
Showings are scheduled over calls and texts, and the calendar is right about half the time.
Residents without one channel
Notices, maintenance, and emergencies go out by email, paper, and group chat, and nobody knows who saw what.
Devices nobody watches
Smart locks, thermostats, and sensors are installed, then only checked when a resident complains.
02 · The approach
How I would build it
Pick a tab. Three map to work that has run in production; listings and MLS feeds would be new work.
Resident and community portals
A staff portal for resident groups, alerts, events, and calling, applied to buildings and their residents.
- Resident groups
- Emergency alerts
- Event scheduling
- Audio and video calling
- Push notifications
- Serverless backend
03 · Stack
The tools behind the work
What the related work runs on, and what a listings build would add.
- Portals
- Angular
- Next.js
- React
- Ionic
- Backend
- NestJS
- Django
- PostgreSQL
- AWS SAM
- Devices & alerts
- Google Nest SDM APIs
- Firebase
- OneSignal
- Payments
- Stripe
04 · Privacy & security
Residents' data, handled like it matters
Property systems hold addresses, schedules, and door access. These come first.
Roles for residents, staff, and agents
Each role sees its own slice, enforced at the API.
Device access is audited
Every lock or device command is logged with who sent it.
Payments with the processor
Deposits and rent go through Stripe; card and bank details never touch the app.
Resident data kept to the minimum
Only what operations need, with retention set when the lease ends.
Secrets out of the repo
Device and feed credentials live in a secret store, never in an app bundle.
Alerts with an owner
Emergencies route to a person and escalate if nobody acknowledges them.
Engineering practices, not legal advice. MLS data licensing, fair-housing rules, and local privacy laws are for your broker and counsel to confirm.
Running more doors than your tools can handle?
Tell me how tours, residents, and devices are managed today. I will come back with what I would connect first, and be clear about which parts would be new for me.
