NEW VIDEO: How Senior Engineers Actually Build with AI in 2026 | Build a Full Stack Job Applications Platform 🚀

Building a project like this usually takes a team of devs at least a month.

I just built it in a few days - without writing a single line of code by hand. And by the end of this video, you'll have built it, too.

I’m showing you exactly how to build JobPilot.

It’s a full-stack AI agent that completely automates the exhausting parts of the job hunt:

✅ Finds jobs, then scores them against your profile.
✅ Deploys real browsers across the web to deeply research the company behind the listing.
✅ Automatically writes your cover letter and tailors your resume to match.

But honestly, the app itself isn't even the best part.

The real value is in the five open-source agent skills I'm giving away:

1️⃣ /architect
2️⃣ /review
3️⃣ /imprint
4️⃣ /recover
5️⃣ /remember

These give your AI agent memory, focus, and the ability to actually ship a project without drifting off course.

That's the actual skill. And it's completely learnable.

You can install them once and use them on literally every project you build moving forward.

Here is the stack we are using to make this project happen:

→ Next.js 16
→ Backend: InsForge
→ Real browser automation: Browserbase & Stagehand
→ Intelligence: GPT-4o
→ Analytics: Posthog

If you know basic , you can follow along.

By the end of this tutorial, you won't just have a working AI agent - you'll have a system for building anything.

A system that doesn't get replaced by the next model, but instead gets stronger every time you use it.

NEW VIDEO: How to Actually Build Mobile Apps with AI in 2026 | A Complete Beginner's Tutorial 🔥

In this video, you're going to build a full Duolingo clone in React Native, using AI the whole way through.

You won't write a single line of manual code, but you also won't yolo prompts and hope it works.

I'm calling it 'Practical Vibe Coding':

→ App framework powered by React Native & Expo
→ Social authentication & user management with Clerk
→ Talk out loud to a real-time AI teacher with Stream
→ Product analytics and tracking with PostHog
→ Every AI-generated pull request reviewed with CodeRabbit
→ Styled with NativeWind
→ State management handled by Zustand

The app isn't the point, the workflow is.

Use this on anything you build next.

Grab your coffee. Let's go.

I just built a full SaaS app without writing a single line of code.

AI agents handled the implementation.

I focused on the system design.

That’s the real shift happening right now.

The gap isn’t tools. It’s how you think.

If you’ve ever had an AI project start great and then fall apart, you’ll get this.

I broke down the full process here: https://jsm.dev/fb-yt-ghost

NEW YOUTUBE VIDEO: Do you actually need to learn another JavaScript framework to get hired? This time… yes! 🔥

I just dropped a two-part video tutorial:

1️⃣ A FREE 3-hour TanStack Start crash course
2️⃣ Build and deploy a Full-Stack Marketplace App with TanStack Start

Here’s why this one matters 👇

Every major infra company is betting on TanStack Start.

Cloudflare, Netlify, Clerk, Neon are all building first-class integrations.

That's not marketing. That's infrastructure companies choosing where their devs will be in 2 years.

That’s a signal! ✅

TanStack Start fixes what other frameworks made painful:

❌ Hydration errors → gone
❌ “use client / use server” confusion → gone
❌ Vendor lock-in → gone (deploy anywhere JS runs)

You keep the React mental model - without the ceremony.

In this video, you’ll learn:

✅ Request lifecycle (what’s actually happening)
✅ File-based routing (dynamic, splat, pathless layouts)
✅ Loaders vs useEffect (and why it matters)
✅ Server functions (built-in RPC, no tRPC install)
✅ API routes for webhooks
✅ SEO + metadata

Then, you'll build 'Skilled' - a Full-Stack Agent Skills Marketplace using:

→ TanStack Start + Router + Query (the full ecosystem!)
→ React 19
→ TypeScript
→ Tailwind CSS
→ Clerk
→ Firebase Data Connect
→ PostHog
→ CodeRabbit

From empty folder... to deployed app! 🔥

If you want to go further, the PRO course is live TODAY. It picks up where the video ends:

→ Submit page with Zod + server mutations
→ Streaming search
→ SSR detail pages
→ Optimistic bookmarking
→ Route masking, middleware, caching internals
→ Testing, error boundaries, production deploy

Grab it here → https://jsm.dev/fb-tanstack-pro-course

‼️ Day Zero pricing is live for 7 days ONLY!

This is the lowest price it’ll ever be. You get lifetime access PLUS direct input on what lessons get built next.

After 7 days, the price goes up. After the course ships complete, it goes up again. 😱

NEW VIDEO: I Vibe Coded a $50K Website in One Weekend! 🔥

You can almost feel the basketball through the screen.

- Scroll-driven animations move the 3D model through sections like a cinematic sequence.
- Hover effects. Sound effects.
- A full interactive product showcase.

But here’s the part nobody online knows.

‼️ The developer behind this project - “The Bugged Dev” on X - is actually on our team!

We sent them on an incognito experiment.

No real name.
No portfolio.
No credentials.

Just one developer + an AI agent building projects.

Within weeks, something interesting happened.

• The creator of Three.js noticed the work
• 5 client projects followed
• And even a job offer

All from someone with zero reputation online.

This wasn’t AI magically building a website.

It was a process.

Most developers use AI like autocomplete:

“Here’s a screenshot → build this.”

Sometimes it works.

Most of the time it’s messy.

Instead, we use a structured workflow for agentic development.

In this video, I'm going to rip this entire project apart - every feature, every decision.

By the end, you'll have a system you can use to build projects like this for yourself and your clients.

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

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?

Grab a coffee.
