Calculations in the browser

Calculation and formatting inputs are processed on the device, without uploading them for processing.

Designed for different markets

Country, currency and language settings adapt the tools. A service worker supports repeat visits offline as an installable progressive web app.

Delivery and quality

Cloudflare delivery, with Vitest unit tests and Playwright end-to-end tests. Optional feedback uses a separate server-side delivery flow.

Implementation and architecture

A full-stack web platform

A Next.js and React frontend connects to a C# and .NET API. Separate application, domain and infrastructure layers organize the backend.

Search and background processing

PostgreSQL with pgvector supports the data and vector-search foundation. Redis and a dedicated worker support the wider application.

Platform and delivery

Docker and .NET Aspire support orchestration, while automated testing and deployment workflows help the portal evolve reliably across its markets.
