How I Solve Impossible Problems

Three abilities that turn "it can't be done" into production code

I See Patterns in Chaos

Give me confusing PDFs with no text layer, scattered data across 30 websites, or millions of unstructured records, I'll find the hidden patterns and build a system that extracts exactly what you need. Chaos becomes structure.

I Learn Technologies Instantly

Node.js project with zero experience? Mastered it in weeks. New database type? I'm productive day one. Unfamiliar API? Integrated by afternoon. I don't memorize syntax, I understand underlying patterns that work across all technologies.

I Feel Systems From Inside

I don't stop at surface-level implementation. I dive into PostgreSQL index internals, PDF file structure, browser detection mechanisms. This deep understanding lets me find solutions in places others don't know exist.

About

From Ukraine to Global Impact

Master of Computer Science from National Technical University "Kharkiv Polytechnic Institute"

I chose programming because it felt like magic, the ability to create something from nothing and shape the digital world. Over 6+ years, I've evolved from scraping and parsing specialist to full-stack backend architect building enterprise AI platforms.

What drives me: I'm passionate about making things work optimally. Whether it's reducing query times from 30 seconds to milliseconds, or building Chrome extensions that seamlessly integrate with AI models, I love transforming complex challenges into elegant solutions.

My approach: I prefer working in small teams where I can see direct impact. My tenacity and ability to analyze large amounts of information enable me to solve even the most complex and ambiguous problems. I'm known for quickly grasping new technologies, once a CTO trusted me with a Node.js project despite my lack of experience, and I mastered it fast enough to lead a major feature.
