Real-Time Chat App — MERN + Socket.IO with presence
Actual websockets — typing indicators, online presence, and messages that arrive in order.
Most chat projects poll an API on a timer and call it real-time; they lag, they duplicate messages, and they fall apart the moment two people type at once. This one uses Socket.IO for a genuine push connection — one-to-one and group chats, typing indicators, online and last-seen presence, delivery and read receipts, and history that persists and paginates. It survives the question every panel asks: how do you know a message actually arrived, and in the right order?

What it does
- One-to-one and group chats over a real websocket connection
- Typing indicators and online / last-seen presence
- Delivery and read receipts per message
- Message history persisted in MongoDB and paginated on scroll
- Authentication carried into the socket layer, not just the REST API
- A chat list that reorders as new messages arrive
What the sessions cover
- 01Why websockets, not polling — and what Socket.IO gives you

- 04Message ordering, delivery, and persisting history
- 05Authenticating a socket and mapping users to connections
- 06The React chat UI and keeping state in sync with events
- 07Scaling notes: the Redis adapter and horizontal sockets
- 08Deployment and a full mock viva on the real-time design

The first 3 students get 40% off in exchange for an honest review and permission to show your finished project here. Same build, same sessions, same handover — the discount is the price of going first, and it is not coming back once those seats are gone.

Two things I hold myself to
- Only 2 students from your college get this project in an academic year. On the Mentored tier one module is varied for you — the dataset, the domain, or a feature — so no two submissions read the same.
- You build nothing. You just have to be able to explain it. The project is delivered finished — code, report, diagrams, deployed. Then daily 60-minute sessions on Google Meet after 8:00 PM IST, walking the code you are submitting, ending in a mock viva. Turn up and you will know it well enough to answer anything the panel asks.

Questions students ask
- Do I have to build any of it myself?
- No. The project is built, documented, and deployed for you — code, report, deck, diagrams, and the running application. Your only job is to turn up to the sessions and learn what you are submitting.
- Can I get my own idea built instead of picking from the list?
- Yes. Send whatever your guide approved — or an idea you want built from scratch — through the custom build form. Any stack, any domain. Custom projects are quoted between ₹10,000 and ₹50,000 depending on scope, and run on the same sessions and installments.
- Do I get the source code, or only the explanation?
- You get the full source code on every tier. The Mentored tier adds live sessions where the code is walked through line by line so you can defend it in your viva.
- How do the daily sessions work?
- Sessions are live on Google Meet, one per day, starting after 8:00 PM IST so they do not clash with college hours. Each runs about 60 minutes and covers one module of the project.
- Can I pay in installments?
- Yes. Payment is direct — direct upi / bank transfer — split into monthly installments. Sessions start after the first installment; the complete source, report, and deployment handover comes after the final one.
- I can buy a project online for ₹2,000. Why does this cost more?
- Because that ₹2,000 buys a zip file. Nobody explains it to you, the same file has been sold to hundreds of students, and it collapses the moment your examiner asks why you chose that database. What you are paying for here is a project built for you, capped per college, and the sessions that make you able to answer for it. If a zip file is all you need, buy the zip file.
- How do I know you will not disappear after I take money?
- Payment is split across months, so you are never paying for work you have not seen — you watch the code in sessions from the first one. If I fail to deliver what the project page promised, your remaining installments are cancelled and the last one is returned. I also have a name attached to this: the same site carries my portfolio, my published work, and my public repositories. That is not something I would burn for one project.
- What if my guide rejects the project or asks for changes?
- Changes your guide asks for during review are made at no extra cost — that is part of the build, not a new scope. If your guide rejects the topic outright before work begins, you can switch to a different project or stop with nothing further owed.
- Will another student at my college submit the same project?
- No. Each listing is capped to a limited number of students per college per academic year, and the Mentored tier varies one module — the dataset, the domain, or a feature — so two builds are never identical.
- Who actually builds and teaches this?
- Yaseen Khatib — a Senior Full-Stack AI Engineer. The same person writes the code and runs the sessions, so every answer in your viva prep comes from whoever wrote the line you are asked about.
