Project
A mortgage portability neobank prototype. When a homeowner sells and buys, PortKey lets them carry their existing low-rate mortgage to the new property — instead of refinancing at today's rates. Your rate moves with you.
App Router with TypeScript throughout — server components for layout and metadata, client components for interactive calculator and application flows.
Savings visualizations and rate comparison charts that make the financial case for portability legible at a glance — key for an investor demo context.
Accessible component primitives styled with Tailwind — rapid iteration on UI without sacrificing polish or keyboard accessibility.
Models the blended monthly payment across the carried mortgage and a gap loan at current market rates — showing homeowners exactly what they'd save versus a full refinance.
A single app surfaces three distinct views: consumer portal for homeowners, loan officer workflow for lenders, and an admin marketplace overview for internal stakeholders and investors.
Fully interactive with realistic financial modeling and no backend dependencies — the entire prototype runs client-side via localStorage, making it instantly deployable for pitches.
