Custom MERN App with Telegram

I’m ready to commission a full-stack web application built entirely on the MERN stack—MongoDB, Express.js, React.js and Node.js. The build must be clean, modular and API-driven so the same services can power both the web version and any future mobile clients.

Core requirements
• Front-end in React with a responsive UI/UX that looks and feels native on desktops, tablets and phones
• Robust Node/Express backend, including well-structured APIs, authentication hooks and role management placeholders
• MongoDB data models designed for scalability and quick queries
• Seamless integration with Telegram (bot or API, depending on the flow we decide) for real-time messaging/notifications
• Analytics wired through Segment so we can pipe data to any source later
• Automated test coverage, cross-browser QA and performance tuning before hand-off
• Deployment scripts or Dockerfiles that let me push to production with a single command
• Up to two weeks of post-launch support to fix any critical bugs that surface in the stabilization window

Deliverables
1. Source code in a private Git repo with clear commit history
2. Technical documentation covering the architecture, API routes and environment variables
3. Production build running on my server (or a cloud service we pick together)
4. Walk-through session showing the deployment pipeline and basic maintenance steps

If this aligns with your expertise in React, Node, MongoDB, Telegram Bot API and Segment, let’s talk timelines and milestones.
