Hello, I reviewed your requirement and understand you need a FULL-FEATURED REAL-TIME CHAT BACKEND for mobile and web, built with Node.js/Express and Supabase (PostgreSQL + RLS), including one-to-one, group chats, friends system, event sharing, temporary photo messages, and online status tracking. I have 10+ years of experience, I can design a clean, scalable, production-ready architecture that supports real-time messaging using Supabase Realtime or WebSockets, and secure data access with RLS policies. Key deliverables: CHAT CORE: Conversations, messages, read/unread counters, timestamps FRIENDS SYSTEM: requests, accept/reject, friend list, search GROUP CHAT: creation, membership, admin controls EVENT SHARING: share events inside messages with metadata TEMP PHOTOS: auto-delete after 24h using scheduled jobs ONLINE STATUS: presence tracking + last seen SECURITY: RLS rules, role-based access, input validation REAL-TIME: Supabase realtime or WebSockets + fallback strategy DOCUMENTATION: API docs + deployment notes I have some queries to ask regarding the project to proceed further. Awaiting your positive response. Thanks

Hello, Thanks for the detailed description. I understand this as the first production phase of a social chat system, not a demo feature. The goal is a reliable backend that supports real-time messaging, friendships, and groups while remaining secure and extensible for future phases. The critical work here is designing the data model and access rules so that every message, counter, and presence update is consistent and properly isolated. Supabase can handle this well, but only if RLS policies are explicit and tested across all chat paths: one-to-one, groups, unread tracking, and temporary messages. Ephemeral photos, in particular, need deterministic expiry and deletion logic so they disappear reliably without breaking conversation state. My approach would be to start by validating the chat flows and schema, then implement real-time delivery with clear ownership of message state and retries. Presence and last-seen tracking would be implemented conservatively to avoid unnecessary load. The focus is correctness, predictable behavior under reconnects, and clean APIs that mobile and web clients can consume without special cases. Final timeline and budget will be confirmed once scope details and acceptance criteria are aligned.

Hello, I have 5+ years of experience building real-time applications using MEAN/MERN stacks and mobile platforms (Android, iOS, Flutter), including chat systems, notifications, and social features. I can design and implement a secure, scalable in-app messaging backend using Node.js/Express with Supabase (PostgreSQL + RLS) and real-time capabilities. I will structure the database to support users, friendships, conversations, messages, group chats, unread counters, online/last-seen status, and temporary media with auto-expiry jobs. Real-time delivery can be handled via Supabase Realtime or WebSockets, depending on your preference and scale needs. The system will include: One-to-one and group messaging Friends & requests flow Conversations list with unread counts User search and event-sharing inside chat Ephemeral photo messages (24h auto-delete) Secure APIs with role-based and RLS enforcement You’ll receive clean, documented, production-ready code and database schema, plus guidance for integrating with your mobile and web apps. I’m interested in long-term collaboration and can start immediately. Let’s discuss your current setup and timeline. Best, Bhargav

@DeveloperStation

Hi, We’ve built several real-time chat applications using Node.js, WebSockets, and Firebase, including a social media platform with features like friend requests, direct messaging, and group chats. We also developed a dedicated chat API for a different product, which was later integrated into a mobile app. For your project, we can use either WebSockets or a server-sent events (SSE) approach, depending on which is more suitable for your specific use case. Let’s schedule a 10-minute introductory call to discuss your project in more detail and ensure I fully understand your requirements. I usually respond within 10 minutes. I’m eager to learn more about your exciting project. Best, Adil

This needs to be built as a reliable communication backbone, not a feature experiment. I’ll approach it by first locking down data structure, permissions, and message lifecycle, then layering real-time delivery on top so nothing breaks under load. The system will support one-to-one and group chats through a unified conversation model, ensuring unread counts, last messages, online status, and event sharing behave consistently. Friend requests, search, and visibility rules will be enforced at the database level so users only ever see what they’re allowed to see. Temporary photo messages will be handled with controlled expiry so deletion is predictable and auditable. The end result of this phase is a stable, production-ready chat backend that your mobile and web apps can depend on, with clean boundaries for adding future social features without rework. I’m ready to take ownership of this and move it forward. Regards, Sagar P.
