NEW VIDEO: Build and Deploy a Full Stack AI Voice Learning App! 🔥

What if you could upload any PDF…

Ask it a question out loud…

And hear it respond in a real human voice?

That’s exactly what we’re building today!

We’ll even turn it into a real SaaS that you can actually charge money for! 😱

Tech stack:

✅ Next.js
✅ MongoDB
✅ TypeScript
✅ Tailwind CSS
✅ Vapi (real-time voice AI)
✅ Clerk (auth + subscriptions)
✅ CodeRabbit (AI code reviews)

This isn’t just another AI demo.

It’s a sellable, voice-powered SaaS.

Let’s build it ➡️ https://jsm.dev/fb-bookified

02/20/2026

I built an AI agent that lives on a VPS and I control it entirely from Telegram.

🔗 https://jsm.dev/ig-openclaw

It can deploy apps, review PRs, automate emails, run research, and execute scheduled tasks.

In this video, I show you exactly how to set it up from scratch.

No fluff. No theory. Just practical implementation.

If you’re serious about AI agents, this will change how you build.

NEW VIDEO: Build and Deploy a Full-Stack AI App for Free (No Credit Card Required)

👉 https://jsm.dev/fb-roomify

Ever opened a tutorial to build an AI SaaS…

…only to realize you need a credit card, 12 API keys, a separate backend server, and more?!

What if you could skip all of that?

In this video, I’ll show you how to engineer a production-grade AI SaaS from the ground up.

You’ll build Roomify - an AI-powered architectural visualization platform that transforms 2D floor plans into photorealistic 3D renders!

Here’s what you’ll implement:

→ Instant 2D-to-3D AI visualization
→ Persistent media hosting with permanent public URLs
→ Dynamic project gallery with personal history tracking
→ Side-by-side comparison tools
→ Global community feed with one-click sharing
→ Clean ownership & metadata mapping
→ Modern export functionality

Tech stack for 2026:

✔︎ React + Vite
✔︎ Tailwind CSS
✔︎ Puter (serverless workers, AI rendering, file hosting, KV storage)
✔︎ CodeRabbit (AI code reviews)
✔︎ JetBrains Junie (AI copilot for complex worker logic & prompts)

By the end of this video, you won't just know how to build an app, you'll know how to engineer a SaaS that is lightweight, instant, and completely self-contained.

So, are you ready to build the future of AI architecture?

NEW VIDEO: WebSockets Crash Course | Build a High-Frequency Sports Broadcast Engine! 🚀

Have you ever opened a video to learn real-time apps, only to watch someone import a paid service and call it “magic”?

Then, you hit an interview and get asked about handshakes, ghost connections, or why streams freeze - and everything falls apart!

In 2026, anyone can use AI or pay for a service.

Engineers build the service.

1️⃣ Here’s what you’ll actually learn:

→ How a WebSocket starts life as HTTP
→ What the 101 Switching Protocols response really does
→ How full-duplex communication lets servers push data instantly
→ How to keep thousands of connections stable
→ Why ghost connections silently kill servers
→ How ping-pong heartbeats keep everything alive
→ Broadcast vs unicast vs rooms
→ Pub/sub architecture for live sports and large-scale events
→ Back pressure, memory safety, and when WebSockets aren’t the right tool

2️⃣ Then, we go from theory to production:

You’ll build a high-fidelity live sports match engine that broadcasts scores and play-by-play commentary - in under 10 milliseconds! 😱

Production stack:

→ React for a real-time UI that updates like a stadium scoreboard
→ Node.js for the event-driven core
→ Express for the handshake and REST APIs
→ Native WebSockets (ws) for protocol-level control
→ PostgreSQL + Drizzle ORM
→ Arcjet for security, rate limiting, and DDoS protection
→ Site24x7 for monitoring latency and system health
→ CodeRabbit for clean, scalable, production-ready code
→ Hostinger for deployment

By the end of this course, you won’t just say, “Yeah, I can build a real-time app.”

You’ll explain exactly how the data moves through the wire.

If you’re serious about leveling up from watching tutorials to becoming hire-ready, this one’s for you.
