Internal platforms
The software a team runs its day on: search, records, approvals, scheduling. Shaped around the workflow you already have, not a template you have to bend to.
Custom application development
Custom application development, built to last.
Web applications designed around how your business actually works: who signs in, what each person is allowed to see, where the data lives, and which systems it has to talk to.
What we build
Client intake and portals
Multi-step forms, uploads and summaries on the client side, and an admin side to review, filter and update every submission.
Multi-client platforms
One application serving many companies or teams, each seeing only its own data, with role-based administration on top.
Replacing spreadsheets and legacy software
Moving a process out of shared documents or an aging system into a real database, one piece at a time, without stopping the business.
Built the way it will be maintained
Access enforced in the database
Row-level security, role-based permissions and audit logging, so a mistake in the interface cannot show anyone data they should not see.
Typed end to end
TypeScript and C# from the schema to the screen, so a change in one place fails at build time instead of quietly in production.
Connected to the systems you use
CRMs, ad platforms, booking software and spreadsheets: the application reads from and writes to them instead of becoming one more island.
Shipped through a pipeline
Releases go out through CI/CD with monitoring in place, so shipping a fix is routine rather than an event.
Applications in production
Proximity Search Platform
Senior Placement Search
An internal placement tool for Care Advocates in San Antonio and Austin that turns a 1,200-line provider document into a searchable database with proximity ranking as the primary interface: enter an address or zip and the nearest suitable homes come back distance-ranked, narrowed in place by beds, care type, budget and license status.
