I will add live notifications and websocket features to your saas
Ali Haider
About this gig
I build real-time features that actually hold up in production not just a chat demo that breaks the moment two people type at once
If your SaaS needs live notifications, instant chat, online presence, or "who's typing" indicators, I add this directly into your existing Node.js/Next.js app using Socket.io. No starting from scratch I work inside your current codebase.
What I handle that most basic implementations miss:
Reconnection logic when internet drops for a few seconds, users don't lose connection or get duplicate messages.
Authentication on socket connections so random people can't connect and listen in.
Scaling beyond one server if you're running multiple instances, I set up a Redis adapter so events sync correctly across all of them. Most freelancers skip this and real-time features silently break once you scale.
I recently built SyncVela, a real-time collaboration platform with live messaging, typing indicators, and presence detection from scratch link in my portfolio.
Stack: Node.js, Express, Next.js, React, PostgreSQL, Prisma, Socket.io, Redis, TypeScript.
Message me before ordering if your need doesn't fit a package I'll tell you honestly which tier fits.

I'm a full-stack developer who got tired of "real-time chat apps" that fall apart once more than two users connect. I specialize in what most tutorials skip — connection handling that survives bad internet, authentication that stops randoms from listening on your sockets, and architecture that doesn't break once you scale.
Stack: Node.js, Next.js, React, PostgreSQL, Prisma, Socket.io, Redis. I built SyncVela, a real-time collaboration platform with live messaging, typing indicators, and presence detection, from the ground up.
I work inside your existing codebase, not from scratch.

FAQ
Do you need access to my codebase?
Yes. I work inside your existing project, not a separate demo I hand over later. GitHub/GitLab access or the relevant backend files are enough to get started.
What if my backend isn't Node.js?
Message me first. I can usually still help by running a small Node service alongside your main backend that talks to it — but I want to confirm feasibility before you order.
Will this actually scale if my user base grows?
A single server setup is fine for low-to-medium traffic. Once you're running multiple server instances, you need the Redis adapter (included in Premium) — otherwise users on different servers won't see each other's real-time updates.
Can you deploy it as well?
Yes — Render, Railway, DigitalOcean, or Vercel-compatible setups. Mention this in your requirements so I scope the time correctly.
I only need a small fix, not a whole feature — can you still help?
Yes, message me with details first instead of ordering blind. I'll quote it properly rather than over- or under-charging you.
