Custom Web Application Build

I need a custom-built web application that moves smoothly from concept to deployment. The core objective is to translate my requirements into clean, reliable code, wrap it in an intuitive interface, and host it on a production-ready environment.

Scope of work
• Work with me to refine the functional requirements, wireframes, and data flow.
• Select an appropriate stack (for example, React or Vue on the front end and Node, Django, or a comparable back end) and justify the choice in terms of scalability, maintainability, and security.
• Build out the application, integrate any necessary APIs, implement user authentication, and set up a database layer.
• Package, test, and deploy to a cloud host, complete with documentation for future maintenance.

Acceptance criteria
1. Feature set matches the mutually agreed specification.
2. Code passes unit and integration tests and ships with clear comments.
3. Deployment scripts and step-by-step instructions are included.
4. A short walkthrough video or live demo URL is provided to confirm everything works as intended.

Please outline your proposed tech stack, estimated timeline, and any relevant past projects when you respond.
