As a developer, you should know core system design concepts.

This helps show potential employers that you can turn design requirements into production-ready code.

This course covers app architecture, API design, caching, networking, databases, and more.

🚨 Someone reverse-engineered the design systems of Apple, Spotify, Airbnb, and 30+ billion-dollar companies.

Packed each one into a single file. Free.

It's called Awesome Design MD.

Drop one file into your project. Your AI agent builds UI that looks like Spotify. Or Apple. Or Airbnb. Instantly.

Not screenshots. Not Figma links. A single DESIGN .md file that captures every color, font, spacing value, button style, and layout pattern from a real website. In a format AI agents read and reproduce.

Here's the difference:

Tell Claude Code "build me a landing page" and it gives you generic UI.

Tell Claude Code "build me a landing page" with Spotify's DESIGN .md in your project and it gives you Spotify.

Here's what's inside:

→ Apple. Premium white space, SF Pro typography, cinematic imagery.
→ Spotify. Vibrant green on dark, bold type, album-art-driven layout.
→ Airbnb. Warm coral accent, photography-driven, rounded UI.
→ Linear. Ultra-minimal, precise spacing, purple accent.
→ SpaceX. Stark black and white, full-bleed imagery, futuristic.
→ BMW. Dark premium surfaces, precise German engineering aesthetic.
→ NVIDIA. Green-black energy, technical power aesthetic.
→ Uber. Bold black and white, tight type, urban energy.
→ Sentry, PostHog, Raycast, Cursor, ElevenLabs, and 20+ more.

Here's how to use it:

→ Pick a design system from the collection
→ Copy the DESIGN .md file into your project root
→ Tell your AI agent to use it
→ Get UI that matches the design language of a billion-dollar company

That's it. One file. Your AI agent now has the design taste of a $200/hour design consultant.

Designers charge $5,000+ for a custom design system. Companies spend $50,000+ building one from scratch.

This is free. 31 design systems. Copy. Paste. Ship beautiful UI.

Works with Claude Code, Cursor, Codex, and any AI coding agent that reads project files.

🚨 Screen Studio charges $89 for this. Someone open sourced the entire thing for free.

It's called OpenScreen. 8,400+ GitHub stars.

You record your screen. It automatically transforms it into a polished, professional demo video.

Auto-zoom into clicks. Smooth cursor animations. Motion blur. Custom backgrounds with wallpapers, gradients, and shadows. Webcam overlays. Annotations. Timeline editing. Export in any aspect ratio.

The exact workflow that Screen Studio sells for $89 and Loom sells as a subscription. Free. No watermarks. No accounts. No subscriptions.

Here's what you get out of the box:

→ Full screen or window capture with system audio and mic
→ Automatic zoom that follows your cursor and clicks
→ Manual zoom with customizable depth and timing
→ Smooth motion blur on pan and zoom transitions
→ Animated cursor rendering with motion effects
→ Webcam bubble overlay with drag-and-drop positioning
→ Wallpapers, solid colors, gradients, or custom backgrounds
→ Text and arrow annotations layered over recordings
→ Timeline trimming and variable speed segments
→ Crop, resize, and export in any resolution or aspect ratio
→ Save and reopen projects anytime

Here's the wildest part:

A developer forked it and built an even more advanced version called Recordly. Full cursor animation pipeline. Native macOS and Windows recording. Zoom behavior that mirrors Screen Studio frame-for-frame. Audio tracks. Webcam overlays with zoom-reactive scaling.

Both are free. Both are MIT licensed. Both work on Windows, macOS, and Linux.

Download. Record. Export. Done.

100% Open Source. MIT License.

@bmsquantum Hello there!

[Vanessa Castro @vane_webdev]

Tailwind CSS tip: group vs peer

group → Parent controls children
peer → Element controls its siblings

Use cases:
• Hover cards → group-hover
• Form validation → peer-checked
• Interactive UI states

Simple rule:
Parent interaction → group
Sibling interaction → peer

Damnn 😱
Most developers are using Claude Code wrong.

They open the terminal...
write a prompt...
and expect magic.

That’s not where the real power is.

Claude Code is actually a 4-layer AI engineering system:

1️⃣ CLAUDE.md → project memory
Architecture, rules, commands, conventions

2️⃣ Skills → reusable knowledge packs
Testing workflows, code review guides, deploy patterns

3️⃣ Hooks → deterministic guardrails
Security checks, enforced rules, automation

4️⃣ Agents → specialized sub-agents
Break complex tasks into parallel workflows

Once you structure these properly, something interesting happens:

Claude stops behaving like a chatbot.

It starts behaving like a real AI dev system.

Most engineers miss this because they jump straight to prompting.

But the difference between average output and production-level results usually comes down to setup.

If you're building with AI agents in 2026, learn the system — not just the prompt.

I made a Claude Code Starter Pack explaining everything.

I'll DM it to a few people.

Future AI dev workflows won't be prompt-first.

They’ll be system-first. 🚀
