Data Pipeline (reverse-engineering + ETL)
–Reverse-engineered undocumented game data formats — binary PAK archives (Oodle decompression via FFI), proprietary datasheet format, CryEngine 3D models, nested loot tables
–Designed a TypeScript ETL system with 11 converters for 28+ data types: recursive loot table resolution, probability calculations across nested weighted pools, perk scaling formulas
–Built asset extraction: PAK file parser, CGF→Collada→glTF 3D model conversion, DDS→PNG texture processing
–Processed 16,000+ items, 5,000+ creatures, thousands of recipes across 9 languages into Meilisearch indexes
Website Features
–Item detail pages with 15+ conditional tabs, gear score slider with real-time stat recalculation, recursive crafting chain viewer, loot probability trees
–Interactive character builder: per-slot gear score control, weighted perk probability display, 3D model preview (React Three Fiber), community build sharing
–Expedition/mutation system (10 difficulty tiers), creature database with per-level scaling, trade skills optimizer for 17 professions
–Community features: rich text comments with @mentions and Discord webhooks, image gallery with moderation, articles via Strapi CMS
Infrastructure & Performance
–Handled 100k+ unique users/hour on a Hetzner server: 20 Next.js instances, pre-generated JSON files replacing DB reads, blue-green zero-downtime deployment
–Full SEO: hundreds of thousands of static pages, 9 locale-specific domains, JSON-LD, dynamic OG images, chunked sitemaps
–Twitch extension: game-aware stream overlay with broadcaster config
Worked on projects with several agencies. Built websites, online stores, and integrations using Laravel, Symfony, WordPress, Bitrix, and CodeIgniter. 10+ projects total.
Programming Instructor
Sep 2019 – May 2023
ANO “Makhaon” · part-time
Taught React and React Native courses to high school and university students. Also ran courses on backend JavaScript and cross-platform mobile development.
Web tool for cleaning up terminal-copied text: strips whitespace, dedents, counts tokens
Education
No formal degree. Grew up at a family-run programming school (ANO “Makhaon”), into CS since age 7, writing Pascal since 9. Enrolled in university (Information Security) at 17 with high expectations, but it was a disappointment — at that point I was already teaching programming at Makhaon and knew the CS curriculum years ahead. Dropped out and went straight into professional work.
About
Been building things with code for over 20 years. Over 15 regional, national, and international competition wins and awards in programming and CS (2004–2013), including 1st place at a national programming contest (24 bit) and top-20 at the Belarus–Russia science & tech summit. Governor's Scholarship (2012), Presidential Scholarship (2013).
