Vue 3 + TypeScript on the front, Django + DRF on the back. - Evolve our core engines. Loan pricing and investor eligibility matching. - Integrate with the mortgage ecosystem. LOS platforms, due diligence providers, credit and valuation vendors. - Design data models and background pipelines that stay fast as volume grows. - Write the tests that keep it all honest. pytest, Vitest, Playwright.
