Hello.
I am ready to implement an adaptive web calculator for calculating paint proportions in a simple, modern, and user-friendly format.
I understand the task: it is important not just to create a form with fields, but to assemble a clear tool that the craftsman will feel comfortable using right during the procedure — quickly, without confusion and unnecessary actions.
I can create:
— an adaptive web calculator for mobile devices
— a clean and understandable interface
— correct calculation logic based on your formulas
— a convenient structure for future changes and improvements
— a neat implementation without overloading with unnecessary functionality
For implementation, I would suggest React for the frontend, and if data storage, settings, or further expansion is needed — we can immediately lay down a lightweight backend on Node.js. If a quick working tool without a complex backend is needed at the start, that can also be done.
I am ready to quickly get to work and, after a brief agreement on the calculation logic, immediately start the implementation.

Good day.
I can implement SmartBrow as a separate web application with a focus on calculation accuracy, a simple usage scenario, and ease of use on smartphones during the procedure.
From the description, I see that it is important not just to create a beautiful interface, but to correctly assemble three key parts:
mathematical logic, mobile UX, and a convenient architecture, so that the product can be painlessly expanded in the future, including towards AR.
Here’s how I envision the implementation:
– development of a web calculator application with a step-by-step parameter selection
– implementation of accurate calculation logic based on your algorithms
– responsive interface focusing on iPhone and Android
– clean, modern UI in a Beauty-Tech style
– convenient code structure for further refinements
– preparation of a foundation for future scaling of functionality
For the tech stack, I propose:
– Frontend: Next.js or React
– Backend: Node.js / NestJS or lightweight API if the logic is not complex
– Database: PostgreSQL or MongoDB if it is necessary to store formulas, scenarios, history, or profiles
– For a fast and convenient mobile-first interface, I can also offer a PWA solution, so the application is easy to use both on the phone and in the browser without separate native development
Why this approach:
– React / Next.js is well-suited for a fast, clean, and responsive interface
– calculation logic can be separated into its own layer for easy testing and modification
– PWA provides a good balance between cost, speed of launch, and convenience for users
Regarding timelines:
– MVP of the calculator: 7–12 working days
– if a cabinet, saving scenarios, formula history, or admin panel is needed: 2–3 weeks
Regarding costs:
– basic version of the calculator: 500–900 USD
– if with extended logic, data saving, roles, or admin panel: from 1000 USD
About similar projects:
I work with services where calculation logic, forms, parameter selection scenarios, and convenient mobile UX are important. If having a portfolio with similar calculators is critical for you, I can separately provide a review tailored to this vacancy in a more specific style, without unnecessary general phrases.
I am ready to get involved, help with the logic design, and propose an implementation that will be convenient to develop further.

Good day!
I will create/improve a web application focused on a paint and oxide proportion calculator for use on phones during the procedure: minimal steps, large touch areas, clear prompts, "clean" beauty-tech UI. I plan to include an AR block as a future extension (a separate phase), but for now — stable math + convenient UX.
Success criteria (how I measure the result)
Mathematical accuracy: formulas separated into a separate module, unit tests for key cases + manual verification with a set of "reference" examples from you.
Responsiveness: mobile-first layout, testing on iOS Safari / Android Chrome, correct keyboards/fields, stable operation in portrait mode.
Code cleanliness: TypeScript, modular structure, minimal "magic" in the UI, documentation on formulas/parameters — to facilitate easy product development.
UX/UI: modern typography, calm color palette, contrast, basic level accessibility, response speed.
Stack
Next.js + TypeScript + React (fast UI, easy to scale)
styles: Tailwind CSS (or CSS Modules — according to your brand book)
formula tests: Vitest/Jest
deployment: Vercel/Netlify or your VPS + CI (as agreed)
if needed: PWA (icon on the home screen, offline shell — we will discuss)
Budget: 7000 UAH Deadline: 10 days
We will develop the SmartBrow web application using the following technology stack:
- Frontend: React/Next.js for a responsive and aesthetic interface in the Beauty-Tech style.
- Backend: FastAPI (Python) for fast and accurate calculations with scalability options.
- Database: PostgreSQL for storing formulas and user settings.
- AR integration: We will prepare the architecture for future integration of AR elements.
Our approach will ensure:
1. Mathematical accuracy: We will implement calculation algorithms based on the schemes you provide, with the possibility of verification through testing.
2. Adaptability: The application will run seamlessly on iOS and Android, including optimization for operation directly during the procedure.
3. Code cleanliness: The architecture will be modular, with documentation for future changes.
4. UX/UI: The design will be developed with the needs of the beauty industry in mind — an intuitive interface without unnecessary classes.
