Found Description

Overview: I am looking for a Senior TypeScript Developer to build a high-conversion, multi-step booking flow for a service business.
We are migrating our current logic from a legacy JavaScript repository into a clean, modern TypeScript environment.
The system must be built with future-proofing in mind, as we will eventually move from static pricing to a full Timewave API integration.
Key Responsibilities: - Migration & Refactoring: Port existing booking logic from JS to TS, ensuring strict typing for all service models.
- Dynamic Pricing Engine: Build a flow that calculates pricing based on $m^2$ (square meters) and service type
- State Management: Implement a robust Step-by-Step UI (Service Selection to SQM Input to Calendar/Time to Checkout).
- API Readiness: Structure the data fetching layer so that static price-lists can be swapped for TimeWave API endpoints (/articles, /gaps) without refactoring the UI.
- Component-Based UI: Ensure the frontend is light...
