BY SENIOR CONSULTANTSPROJECT-FIRST COURSESWEEK 1 FREE · EVERY COURSE

Every course ends with a real system — built by you.

Project-first courses from senior consultants who ship — microservices & AWS, SAP Commerce, composable storefronts, enterprise integration. You don't watch: you build, break, explain, and ship the real thing.

No card, no account — Week 1 of every course is free.

THE METHOD

Four moves, repeated until it's instinct.

Every week of every course runs the same loop — the way consultants learn on real projects, compressed into 90-minute lab sessions.

01

Build

90-minute labs from an empty folder. Real commands, real errors, real commits.

02

Break

Known-issues drills: debug the exact failures that bite in production, on purpose.

03

Explain

Interview-grade model answers — defend the architecture, don't just type it.

04

Ship

Verifiable acceptance gates — tests green, endpoints live — not a feeling of progress.

REPEAT × 110 SESSIONS — UNTIL THE REASONING IS YOURS
THE BUILD · INSIDE THE FLAGSHIP TRACK

One system. Five metamorphoses.

Scroll — the system rebuilds itself the way you'll build it.

INSIDE A SESSION

What a lab session actually looks like.

This is the real Week 1, Session 1 of the flagship track — readable free, right now, without an account.

90'
A timeline with acceptance gates

Every session is a timed build with a deliverable — you always know what "done" means.

!
Known-issues drills

Port conflicts, silent config, broken migrations — the failures that actually happen are part of the lesson.

?
Hidden solutions + model answers

Try first, then reveal. Every exercise ends with the interview-grade explanation of why.

WHAT YOU WALK AWAY WITH

Proof, not certificates.

Every course ends in artifacts a hiring loop can actually inspect. These are the flagship track's three.

# ADR-001 — Modular monolith with an event seam
Status: Accepted
Context: microservices add network calls, partial failure…
Decision: modules + in-process events; extract along seams.
Consequences: extraction becomes cheap; Kafka in W08…
An ADR trail — decisions you can defend in any system-design round.

FAQ

Before you ask.

Do I need AWS experience?

No. AWS starts Week 13 with a dedicated on-ramp. You need Java basics and Docker curiosity — everything else is built in the labs.

How much time per week?

5 lab sessions × 90 minutes. Most students do one per weekday morning or evening.

Is Week 1 really free?

Yes — all 5 sessions, no card, no account. Sign in (free) only if you want your progress saved.

What if I get stuck?

Every session ships known-issues tables and hidden solutions; community threads open with cohort 2.

Can I skip weeks?

On the per-week plan weeks unlock in order — the system you build is cumulative. Course owners and All-Access members can jump anywhere.

Refunds?

14 days on course purchases and All-Access, no questions asked.
