Customizing Telegram with Extra Features

@mrresearcher99

Hello there, I have carefully reviewed your requirements and I understand that this project is not a simple messaging app, but a Telegram-based secure communication platform with additional custom modules, strong account security, private cloud storage, and a scalable backend. This is exactly the type of system I specialize in. I have 5+ years of professional experience working with Android (Kotlin/Java), Flutter, React Native, Node.js, and PHP, and I have built and customized secure, large-scale mobile applications involving real-time messaging, media processing, cloud storage, and location-based features.

Hi there, I can handle everything listed in your requirements — mobile apps (Android & iOS), backend, admin dashboard, and deployment. I have experience working on secure messaging and real-time apps, including modifying large existing codebases, implementing phone-number authentication, device session control, encrypted media storage, and location-based features. I understand Telegram’s architecture and the implications of extending it with custom modules like private cloud storage, nearby users, events, and media compression while staying compliant with app-store policies. I can deliver clean, documented source code for mobile, backend, and admin panel, along with deployment and architecture documentation, and provide post-launch support as requested. But the budget you mentioned is quite low for this work if you're open to revise your budget , let's connect. Regards, Sagar

Hello, I can help you customize Telegram’s open-source client and backend to build a secure, feature-extended messaging app while strictly respecting Telegram architecture, encryption standards, and app-store policies. I have strong experience working with secure messaging systems, real-time communication, media pipelines, and scalable backends. I understand Telegram’s MTProto flow, phone-number–based authentication, device session handling, and how to safely extend functionality without compromising message privacy. How I’d approach this project: • Start with a deep review of the Telegram client source and server interaction points • Implement app-level PIN lock, single-device session enforcement, and SIM/OTP verification aligned with Telegram-style login • Build a separate Private Cloud Drive module (user-owned, encrypted, S3-based) for media backup, deleted-media restore, and cross-device recovery • Add efficient media compression (WebP, H.265/VP9, Opus) with fast preview and background uploads • Develop Events and Nearby Users as isolated, permission-based modules (no message access) • Design a secure backend (Node.js / Go / Python) with PostgreSQL or MongoDB and encrypted object storage • Web-based admin dashboard for user moderation, events, storage usage, and visible activity logs only • Ensure clean logout and full restoration 15+ years of development exposure ensure my solutions are robust, maintainable, and efficient. Thank you
