I’m building a dedicated customer-support chat for Balesin and need a developer who can deliver a smooth, professional experience on both our public website and our companion mobile apps (iOS and Android). The core must include real-time live chat, an always-available chat-history log, and secure file-sharing so guests can easily send screenshots, PDFs, or photos while speaking with an agent. A single code-base that can serve Web and Mobile (React, Flutter, or a comparable framework) is ideal, but I’m open to separate native builds if that proves more reliable. Back-end choice is up to you—Node, Laravel, Firebase, or another scalable solution—as long as messages sync instantly and are stored safely for future reference. Acceptance criteria • Website widget and in-app chat screen both connect to the same back-end and exchange messages with <1-second latency. • Conversations remain visible when a user refreshes the page, reopens the app, or switches devices. • Users and agents can attach files up to 20 MB; downloads must be virus-scanned server-side. • Basic agent console (web) shows active chats, history search, and file download links. • Complete source code, environment docs, and a short video demo submitted for hand-off.

✅ Lovable AI Expert | AI Development | Game Development ✅ Hi, Thank you for considering this opportunity! I bring extensive experience in implementing custom solutions powered by LLMs, conversational AI, and intelligent automation. Recently I have been working on Lovable AI for developing a gaming platform using it, complete with chat-based agent logic, expressive front-ends, and backend integrations. See here : In other project, implemented a fully automated AI agent system for intelligent meeting creation using ElevenLabs Conversational AI and Gemini (via a custom agent brain). The flow integrates voice interaction, natural language processing, location precision, and frontend. Whether you're building an internal assistant, a public-facing voice agent, or an integrated AI productivity tool, I can help bring your vision to life with robust, scalable architecture and a human-like user experience. I would love to connect and explore how we can contribute to your AI initiative. Regards Ashraf

Hi, I'll build a centralized real-time chat system that connects your website and mobile applications to a single backend, ensuring every message, file, and conversation stays synchronized across all platforms. The solution will include live messaging, persistent chat history, secure 20 MB file uploads with server-side virus scanning, and a web-based agent console for managing active chats, searching history, and downloading attachments. The project will begin with designing the backend architecture and database, followed by real-time messaging integration using WebSockets/Firebase, secure file upload implementation, chat history management, and agent dashboard development. Once the web widget and mobile chat are connected to the same backend, I'll perform cross-platform testing, optimize response times to under one second, and deliver the complete source code, environment setup, documentation, and demo. I specialize in building scalable full-stack applications with real-time communication, secure APIs, and clean architecture. My priority is to deliver a reliable, maintainable solution with smooth synchronization, fast performance, and clear communication throughout the development process. I'd be happy to discuss your preferred technology stack and review your existing website or mobile apps before getting started. Best regards, Usama K

Hi, this is Joshua from Davis. I have strong experience building real time web and mobile products. I understand you need one smooth support chat for Balesin across web and mobile. Your goal is fast live messaging, full chat history, secure file sharing, and a simple agent console. I can build a reliable system that keeps every conversation synced and easy for your team to manage. I would use a shared backend with real time messaging, persistent chat storage, and secure file upload flow. I can build the web widget and mobile screens in one codebase, with agent tools for active chats, search, and downloads. I can communicate in real time in your time zone and can provide a simple demo or part of the project within 12 hours of starting. Q1: Do you want React Native, Flutter, or separate native apps? Q2: Do you already have a backend or should I build one from scratch? Q3: Do you need agent roles, tagging, or canned replies in the console? Best regards, Joshua

I see you're aiming for a seamless, real-time support chat that works flawlessly across web and mobile for Balesin. I’ve built similar chat solutions using Firebase and React Native, ensuring message sync times under 500ms and secure file sharing up to 50MB. My approach would be to develop a shared back-end with Firebase Firestore for instant message updates and cloud storage with virus scanning for attachments. On the client side, I’ll create a unified codebase with React and Flutter to ensure consistency and easier maintenance. I’ll deliver a robust agent console, persistent chat history, and thorough documentation, along with a demo video. Would you prefer native apps for better performance or a single cross-platform framework to speed up development?
