Learning
Programs by specialization
Free programs: backend, frontend, mobile, QA, DevOps. Articles, quizzes, and tests — a route from fundamentals to architecture.
About me
Vadim Vikulin
I help developers grow in their specialization, prepare for tough interviews, and get back to work — on a real product, with a mentor.
17 years in development. I run a backend cluster of 20+ engineers, and I interview and hire people myself.

Over 17 years in development — senior at Deutsche Bank and Raiffeisen, chapter lead, now running a backend cluster of 20+ engineers — I have interviewed and hired dozens of people and grown engineers from mid-level to senior. I distilled all that experience into hundreds of articles organized into learning programs — a system with everything you need to reach senior and pass interviews: from language fundamentals to architecture and system design, with reviews on a real product and career help.

What I do
Not scattered lectures but a system: programs by specialization, mentoring, and career help. What actually lifts a developer past mid-level and gets them through interviews.
Mentoring
Mentored courses
Reviews on a real product, with tests and work acceptance. From mid-level to an engineer who owns a task end to end.
Careers
Interviews and jobs
I prepare you for tough interviews and help with your job search: résumé, portfolio, finding work.
Open source
Method and libraries
Use Case Pattern and reference libraries on GitHub (usecase-pattern, ddd-building-blocks) — what the programs are built on. No vendor lock-in.
Why talk to me
Useful if you're a developer and at least one symptom sounds familiar:
- Stuck at mid-level — your growth stalled and it's unclear how to move on.
- You don't pass interviews: you know the language but fall down on system design and architecture.
- You were laid off — and don't know how to get back on your feet quickly.
- You learn from scattered articles and videos, with no system and no feedback.
All of this powers the learning platform:
