// Who I am
I am a fullstack developer with 15+ years of professional experience. I specialize in building scalable SaaS platforms, high-load Telegram bots, and complex backend systems. I don't just write code — I help businesses turn ideas into working digital products: from database design to final user interfaces and system configuration.
// Own Products
I create and maintain my own SaaS products, which gives me a deep understanding of all lifecycle stages of an application: from user acquisition to infrastructure optimization under heavy load.

// PRINCIPLES
How I Work
Principles that define my approach to every project.
01
Code is a Business Tool
Every line of code must deliver measurable business value. Beautiful code without business results is a waste of time.
02
Transparency at Every Stage
You see progress every 3–5 days. No black boxes: you always know where the project stands and what comes next.
03
Minimum Dependencies
I use proven stacks, not trendy frameworks. Fewer dependencies — fewer support issues 2 years from now.
04
Automate Everything Repetitive
If a process runs more than twice a week, it should be automated. This applies to both my code and client business processes.
05
Long-Term Relationships
70% of my clients return with new projects or refer me. I build relationships, not close tickets.
06
Documentation is Part of the Product
Every project comes with documentation: architecture, API, deployment instructions. Without documentation, a project is dead.
