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.

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. 😱
