The scorecard measures it. Developer Toolkit teaches it.
Six dimensions separate a fast prototype from production-grade software. Wherever you’re still prototype-grade, there’s a track that levels you up — fast.
Tooling & subscription
Get onto terminal/agent-first tools and the plan that actually fits your usage. Stop topping out at copy-paste productivity.
Context engineering
CLAUDE.md, memory, and rules so your agent starts every session informed — not blind.
Extensibility
Skills, MCP servers, subagents, and hooks that turn a stock assistant into your own custom tooling.
Parallelism & automation
Run multiple agents, git worktrees, and auto-PR workflows instead of single-threaded prompting.
Vibe coding & docs
Know when to reach for Lovable vs Claude Code — and keep library docs in context so the agent stops hallucinating.
Operations & hygiene
Cost monitoring, secrets management, and portable dotfiles so your setup survives scaling.
Anyone can ship a prototype. The hard part is production.
From First Prompt
to Deployed Code.
Complete workflows from initial idea to production deployment. Not isolated tips — real end-to-end patterns that ship.

Is this for you?
You know AI tools are the future. The question is whether you'll master them — or keep experimenting without a system.
Perfect for you if...
- You've tried AI coding tools but your output is inconsistent
- You want to be the AI expert your team turns to for guidance
- You use Cursor, Claude Code, or Codex and want production-grade results
- You're tired of AI code that works in demos but breaks in production
- You want to demonstrate measurable productivity gains to your team or leadership
Not for you if...
- You're looking for a magic button that writes code for you
- You only need AI for occasional scripts or one-off tasks
- You're not willing to invest 15-30 minutes per day learning
- You prefer figuring everything out by trial and error
15-30 minutes per day
Most developers see results within 2 weeks. Short lessons designed for busy schedules.

Who delivers
Every engagement is delivered personally by Michał Jaskólski — 26 years in software, 2 IPOs, CTO, author of The AI Engineering Handbook and the 400+ guides on this site. Capacity is deliberately limited.
The math
Even a modest 10% productivity lift on a 25-developer team would free up more than the flagship fee each month — the engagement is designed to pay for itself.
Included with every plan
Four books on shipping with AI — yours free.
Every paid subscription unlocks all four expert guides — 348 chapters across the cross-tool Handbook and three deep, tool-specific books — as EPUB and PDF, in English and Polish.

Common questions
Everything you need to know before subscribing.
Most developers use only 20% of what these tools can do. The gap isn't knowing the tools exist — it's knowing how to use them for production code. We cover advanced context management, custom hooks, Codex SDK, MCP integrations, multi-file workflows, and enterprise patterns that aren't in any official docs. Even power users discover techniques that save them hours every week.
Free tutorials show isolated features. We teach complete workflows—from initial prompt to deployed production code. You'll learn how to combine techniques, avoid common pitfalls, and build maintainable systems. Plus, our content is updated weekly as tools evolve.
Each lesson takes 15-30 minutes. Our "Quick Wins" section has copy-paste recipes you can use immediately. Most developers see productivity gains within 2 weeks of starting.
Yes. One click in your account settings. No questions asked, no hoops to jump through. Your access continues until the end of your billing period.
Yes. 30-day money-back guarantee, no questions asked. If you're not satisfied for any reason, just email us and we'll refund you immediately.
You keep full access until the end of the period you've already paid for — the subscription simply doesn't renew. Your account stays in place, so you can pick up where you left off anytime. Any ebooks you've downloaded are yours to keep.
Yes. Payments are handled by Polar, our merchant of record, which issues an invoice for every charge with the applicable VAT or sales tax for your country. It lands in your inbox right after payment — ready to expense or pass to your accountant.
Unlimited seats for one flat price. Everyone with an email address on your company domain gets full access automatically — no per-seat billing, no invites to manage. Need custom onboarding, white-label, or an on-premise option? That's the Enterprise tier.
Our 100+ recipes cover React, Next.js, Vue, Python, Node.js, Go, Rust, and more. The core patterns work with any stack. We focus on principles that transfer across languages and frameworks.
