I’m Anatolii Merezhanyi.
Software engineer, team lead, and developer mentor.
I’ve spent over two decades building software and working with the people who make it. Today, I bring that experience to individual developer mentoring and web development for businesses.
I’m based in the EU (Poland) and work in English, Ukrainian, and Russian.

Engineering and leading teams
Technical work happens between people.
Building software and leading teams have taught me to look at technical decisions alongside business needs and the people doing the work. A solution needs to make sense in its context, and the reasoning behind it needs to be clear to others.
For example, in mentoring we can take one technical decision from your work and practise explaining the alternatives, its business impact, and your contribution.
From the interviewer’s side
I have conducted technical interviews as well as worked in engineering teams. That experience informs how I help developers prepare: explain what you did, discuss why you made a decision, and make your understanding clear through specific examples.
We can practise both the technical discussion and the way you present your experience, using situations from your own work.
Running jSchoolPL
I ran jSchoolPL as an education business and taught students QA and JavaScript.
In individual mentoring, we start with your situation and the gaps that matter for your next step. I also share technical explanations on YouTube at Styled JavaScript.
Still building
My own engineering work includes BugEater and jZen.
BugEater is a gamified learning platform for QA, Business Analysis, and Project Management, with guided trails and hands-on practice.
jZen is a framework for building applications with Java, Flutter, and a shared data contract.
Building products keeps technical decisions and their consequences part of my everyday work.
Education and credentials
I hold a master’s degree in Electrical Engineering and am a Salesforce Certified JavaScript Developer.
