Hello! I will create a Telegram Web App for your product: I will package the current API and design into a full-fledged application within Telegram.
How I will implement it:
Frontend: React + TypeScript + Vite + Telegram Web Apps SDK, TailwindCSS (or your UI kit).
Authorization: checking initData, session (JWT/HttpOnly), startup parameters/deep links.
Integration with your API: typed endpoints, error handling, cache/state (Zustand/Redux).
UI according to the layout: responsive, dark/light themes, localization (ru/uk/en if necessary).
Deployment: Vercel/Cloudflare/your VPS, connecting a domain for the WebApp.
Handover: source files, README, build/deployment scheme.
…
Stages (3–5 days):
1. Brief: Figma + API specification, domain for web-app, bot token.
2. Framework, /start, authorization, navigation.
3. Layout of all screens + API calls.
4. Tests in the real bot, deployment, project handover.
What I need from you:
Link to Figma/design assets.
API description (endpoints, responses).
Bot data (Bot Token), allowed domain for WebApp.
Cost for MVP (integration + layout + deployment): 5,000 UAH, can be done in stages. Ready to start today and show the first clickable screen on the day of launch.
If that’s okay — send the layout and access, let’s move forward.

Hello, I worked on **Telegram WebApp integration** — I created a web application that combines the Telegram API and an external service, processing over three thousand requests a day.
How do you plan to implement the design in the web app: separately or embedded in the product interface?
I suggest we get in touch, I will provide you with free technical consultation and we will create a development plan + I will tell you about my team!

Good day,
I understand the task - we need to create a Telegram Web App that will combine the Telegram API, your API, and the ready design into a single application that works entirely within Telegram.
I suggest starting with a small MVP milestone: quickly assemble the first working version based on your design so that you can already test the integration with your API and Telegram. After that, we can scale the project - add extended functionality, authorization, analytics, multilingual support, etc.
Regarding the stack: it is optimal to use:
1. Frontend - React + TypeScript + TailwindCSS (flexible, easy to maintain and scale)
2. Backend - Node.js (NestJS / Express) for processing requests to your API and the Telegram API
… 3. Telegram WebApp SDK - for full compatibility with Telegram (authorization, user data transfer, adaptation for mobile Telegram Browser)
This stack allows:
1. to reduce development time (due to ready-made SDKs and responsive design)
2. to lower costs (no need to write a custom backend from scratch - just wrap your API)
3. to avoid Telegram's performance and loading speed limitations
Regarding timelines: MVP version (core functionality + design + API integration) - 3-5 working days
Budget for the initial stage - from $250-400
Full version with extended functionality - discussed after testing the MVP
To propose an accurate plan, please clarify:
2. Is your product's API already documented, or do you need help with the endpoint structure?
3. Is user authorization needed within Telegram (via Login Widget)?
I am ready to quickly get involved, assemble the first version, and show the result in just a few days.

Do you have a ready UI kit/mockups for the Telegram Web App and a short user flow: where the web app opens (button in the menu/inline), what the main screens are, and what methods of your API are needed at the first stage?
Experience: I create Telegram Web Apps with authorization via initData, connecting your API, session storage, data exchange between the bot and the web app, webhooks, and deployment. I will create a lightweight front end (React/Vue or plain JS) according to your design, responsive and Telegram themes, with caching and error handling.
Ready to start immediately: send a short technical specification, endpoints with example responses, and a design reference — I will assemble a minimal prototype and we will agree on the next iterations.
