Public calculators
The strongest feature is the real-time calculator set: affordability, mortgage payment, and points. The forms needed careful input handling because small finance fields can change the result story quickly.

Fishtail Client Product Family
A related family of products for one US mortgage and real-estate client: public Fishtail Mortgage and Fishtail Realty websites plus an internal employee-facing mortgage management app.
What it does
Covers public buyer journeys through affordability, mortgage payment, and points calculators while also supporting employee loan workflows through a separate internal management system.
Project story
Repeat client delivery
One client, public journey plus internal workflow
The Fishtail work is stronger as a client-family story than as one isolated mortgage app. It combines public mortgage/realty lead journeys with an internal employee-facing workflow system for the same business domain.
Internal workflow
The internal mortgage management app adds the operational side of the same client story: employee roles, validation-heavy forms, document upload, reporting views, and workflow-specific screens.
Why it matters
This is not just a brochure-site project. It covers domain-specific frontend work repeated across public websites, calculators, and internal business software for a single client relationship.
Family of mortgage/realty products for one client: public calculators plus internal employee workflows.
Key Highlights
