Engineering fundamentals · in the age of AI

Learn what matters. Learn how it really works.

Not another shallow bootcamp or surface-level course. Live, hands-on workshops led by working senior engineers, the fundamentals that outlast every tool, learned by building it yourself. Online, from Tunisia.

Why Your JavaScript Freezes the Page

Fix a real search box that freezes, flickers, and lies, and finally understand the event loop everyone tells you to "just learn."

You'll leave with

  • Predict the order of any setTimeout / Promise / await
  • Diagnose async UI bugs by name, stale races, freezes, ghosts
  • Reach for the right tool: debounce, AbortController, rAF
Session agenda
  1. 00:00Hook: predict the output
  2. 00:12The model + feel the broken app
  3. 00:22Closures: functions that remember
  4. 00:52Fix the search box: the centerpiece
  5. 01:37The dashboard capstone (live API)
  6. 02:30Wrap + what's next

PostgreSQL Performance: Stop Guessing, Read the Plan

Stop adding indexes at random. Ask Postgres exactly what it's doing with EXPLAIN ANALYZE, then prove your fix made it 50× faster.

You'll leave with

  • Read EXPLAIN ANALYZE bottom-up and find the expensive node
  • Spot a Seq Scan and add the right index, not a random one
  • Prove the fix with a before/after plan
Session agenda
  1. 00:00Fast in dev, dead in prod: the scenario
  2. 00:15Spot the Seq Scan
  3. 00:55The right index: the 50× win
  4. 01:35Why my index is ignored
  5. 02:15Wrap + homework into Session 2

AI Agents Fundamentals: Build One From Scratch

Build a real CLI agent from zero, no framework hiding the magic. Wire up tool calling, the agent loop and evals, add human-in-the-loop approvals before high-stakes actions, then watch your token usage and tame the context window like an engineer.

You'll leave with

  • Build a working agent loop from scratch: tool calling and evals
  • Add human-in-the-loop approvals before high-stakes actions
  • Track token usage and manage the context window on purpose

// How it works

From curious to building, in three steps.

01

Pick a live workshop

Browse the upcoming sessions, each shows its level, its agenda, and what you'll walk away able to do.

02

Save your free seat

Two fields, no account. We email you only about that session and hand you the calendar invite.

03

Show up and build

Join live, type along, break things, and ask anything in the moment. You leave having built it yourself.

// What you'll learn

Engineering that matters in the age of agentic coding.

From the browser to the backend to the agents you build on top, every session goes deep on how it actually works, the engineering that still holds when an AI writes the first draft.

// Who we are

Taught by engineers who actually build.

Most "learn to code" content is shallow by design, express bootcamps and surface-level training that hand you syntax and leave you stranded the moment something breaks. We built the opposite.

01

Senior engineers

Every session is led by people who design and ship real systems for a living, not career instructors reading off slides.

02

Depth over hype

We teach what's happening underneath, the fundamentals that still hold long after this year's framework is forgotten.

03

Built, not watched

You don't sit through a lecture. You build the thing live, break it, fix it, and ask anything as you go.

Don't build alone

Workshops are the spark, the community is where you keep shipping. Ask questions, share what you build, find people on the same path.

Join Discord Join WhatsApp

Discord is our main hub, session links, questions and code reviews all happen there. We're on WhatsApp too if you prefer it.

// FAQ

Questions? Answered.

Is this a bootcamp or a six-month formation?

No. We're not a bootcamp and we won't sell you a 'full-stack developer' badge in twelve weeks. Hands-On is live workshops run by senior engineers, each one a deep dive into how something really works. You build it yourself and walk away with fundamentals that outlast any framework, not a shallow tour of this week's syntax.

Do you just teach people to prompt AI?

No. We use AI in every session, but the workshop is about understanding what it builds, why, and how to fix it when it breaks. That's what makes you an engineer, not a prompter.

Is it really free?

Yes. Workshops are free, no account and no card needed. We're building a community of people who learn by building, that starts with the door wide open.

I'm a complete beginner, can I follow?

Each workshop shows its level. Beginner sessions assume nothing beyond basic computer use, and we go step by step. If you get stuck, you ask, that's the whole point of being live.

What do I need before the session?

A laptop, a browser and an internet connection. If a session needs anything installed, we post a short checklist in Discord and WhatsApp a few days before.

Will it be recorded?

No, and that's deliberate. The value is building along and asking questions in the moment. Show up, type along, and you'll keep more than any recording would give you.

What happens after I save a seat?

Add the session to your calendar (we give you the button), then join Discord or WhatsApp, that's where the join link is posted before the session, along with any prep notes.

Ready to see how it really works?

The next live session has open seats. Save yours and come build with us, your questions answered in real time.
