🔥 Trending Claude Code Mastery: Agentic Coding for Engineers
Use Claude Code — Anthropic's CLI for agentic software engineering — to ship faster. Master hooks, slash commands, sub-agents, MCP integrations, headless mode, plan mode, and custom skills to fit it to your team's workflow.

By the end you'll be able to
- Use Claude Code (the agentic terminal) the way Anthropic engineers use it
- Build skills, slash commands, and hooks that customise Claude Code for your codebase
- Run multi-step refactors, migrations, and bug-hunts with AI as a real teammate
- Avoid the 5 ways Claude Code can mess up a codebase if used carelessly
- Be the agentic-coding-fluent engineer on your team — measurable productivity multiplier
Is this course for you?
This is right for you if you…
- You're a working developer (any stack) wanting your daily workflow to be 2-3× faster
- Your team is rolling out Claude Code and you want to be the one writing the team's customisations
- You're senior enough to know when AI is right and when it's not — agentic coding amplifies judgment, doesn't replace it
Don't take this course if you…
- You're starting from scratch in coding — agentic coding magnifies skill, including its absence. Build for 6+ months first
- You expect Claude Code to write your project for you — that's when codebases turn into expensive technical debt
- You don't have a real codebase to apply this to — most of the value is in your customisations to YOUR repo

Oleksii Anzhiiak is a Software Architect, Senior .NET Engineer, and Co-Founder of ToyCRM.com and ProfectusLab. With over 15 years of experience, he specializes in distributed systems, cloud infrastructure, high-load backend development, and identity platforms. Oleksii designs complex architectures, builds secure authentication systems, and develops modern engineering education programs that help students achieve real career results.
Currently leads architecture for ToyCRM.com — a multi-tenant CRM platform built on .NET. The same patterns and design decisions used there appear directly in the courses: identity & auth, distributed services, code review culture. You learn from someone shipping production code this week, not a textbook.
Syllabus
Five modules to make Claude Code a daily-driver tool in your engineering workflow:
- 1 Module 1: Claude Code fundamentals — installation, CLI basics, project context, CLAUDE.md memory files, IDE extensions (VS Code, JetBrains)
- 2 Module 2: Permissions, settings, and safety — settings.json, allowlists, sandboxing, plan mode for review-before-execute workflows
- 3 Module 3: Hooks and slash commands — pre/post-tool hooks for lint, test, deploy gates; authoring custom slash commands and reusable prompts
- 4 Module 4: Sub-agents and parallel work — Explore, Plan, general-purpose agents; running tasks in parallel; isolating with worktrees
- 5 Module 5: MCP integrations and headless mode — connecting MCP servers to Claude Code, scripting via headless mode, CI integration, custom skills
Prerequisites
Any developer experience. Git & Version Control recommended for newcomers.
Working knowledge of Git, the command line, and at least one programming language. Comfort using a code editor like VS Code.
What you'll build
You leave with Claude Code customised to your actual codebase — your skills folder, your slash commands, your hooks, your subagents. The course pays for itself in the first week of work afterwards because every PR you ship is faster.
- Claude Code basics: prompts, slash commands, plan mode
- Skills, hooks, settings — customising Claude Code
- Multi-step agentic workflows: refactors, migrations, bug-hunts
- Subagents and isolation modes (worktrees)
- When NOT to use Claude Code — taste matters

You already know C#, ASP.NET Core, and how to ship production backends. Here's how to reuse those skills to build serious AI agents with Claude — without throwing away your stack.
Claude Code in Production: What I Learned in 6 Months
Six months of using Claude Code as a daily-driver tool — the workflows that actually save time, the ones that quietly waste it, and the configuration most teams never set up.
When NOT to Use AI Tools as a Developer
Every AI article tells you when to reach for these tools. Almost none tells you when to put them down. After two years of daily use, here's where AI consistently makes engineers worse — and what to do instead.
First lesson on us. Decide after meeting the teacher.
Sit in on the first session. If after lesson 1 you decide the teacher isn't a fit, you don't pay for it — and no awkward conversation. (Trial offer applies to courses with more than 5 lessons; this one qualifies.)
Pricing & what's included
What's included
- 10 live sessions × 2 hours each — taught by the instructor, not a recording playback
- Slide deck for every session — yours to keep and refer back to
- Working code files and any data files used in class — cloned to your machine
- Weekly homework with personal code review from the instructor
- Recording on request — give the teacher a heads-up ("can't make Tuesday, please record it") and the session is recorded for you
Frequently asked questions
How much time per week will this take?
Plan for the live sessions plus roughly 1.5–2 hours of practice per session. Most students who finish on schedule put in 4–6 hours a week total. If you put in less, you still finish — it just takes longer.
What if I miss a class?
Tell the teacher BEFORE the session — "I can't make Tuesday, please record it" — and the teacher records that lesson and sends it to you. Recordings aren't a default catch-up archive; they're produced on request when you give a heads-up. After the lesson you do the homework, bring questions to the next session.
What's included in the price?
Live sessions with the teacher; the slide deck for each session (yours to keep); the working code files and any data files used in class; weekly homework with code review; and recordings of the sessions you give advance notice for. Anything beyond that — a certificate, alumni access, mock interviews — is listed explicitly in "What's included" above the FAQ for the courses where it applies.
What if I sign up and the teacher isn't a fit?
For courses with more than 5 lessons, the first session is effectively a trial — if after lesson 1 you decide the teacher isn't a fit, you don't pay for it. We'd rather you walk away after one lesson than push through 9 weeks of bad chemistry. (Courses with 5 or fewer lessons are short enough that the standard pricing applies — the trial offer doesn't make sense at that length.)
Can I get a refund partway through?
Yes, while more than half the course is still unused — i.e. you've attended fewer than 50% of the lessons. The refund covers the unused portion proportionally. Past the halfway point we don't refund, on the assumption that the value has been delivered.
Can I switch the language of instruction?
The live sessions run in the language listed under "Available Languages" above. Slides and code files are typically available in all four (English, Russian, Ukrainian, Georgian). Many students attend sessions in one language and read materials in another — that's normal.
Will I be ready for a real job after this course?
One course rarely gets anyone hired by itself — for any field. What this course gives you is the foundation a junior hiring manager expects: working code you wrote yourself, the vocabulary to read other people's code, and the practice habits that make you employable. The honest answer to "am I ready?" is on our roadmap (link in the page header) — open the level you want to reach and read the "You're ready when" checklist.
Can I pay in instalments?
Yes for courses with a "Monthly Payment" option in the at-a-glance ribbon — usually two or three equal monthly payments. Courses without that option are paid in one go. If the price is the blocker, write to us — we look at every case.
