Nikita Tkachenko

I’m a full-cycle software developer who independently architects, builds, and operates production systems. My flagship is PM5Script (pm5online.ru), a live management platform for a competitive online football league where I’m the sole developer—from database design and backend/frontend to deployment and production operations.

I built 10+ interconnected modules, including a money-critical transfer market (bid-based fund reservation, taxes, deal limits, loans, swaps, drafts) safeguarded against double-spending and race conditions, plus a tournament engine in 5 formats with automated scheduling, deadlines, and trophy awarding. I also implemented ratings, suspensions, payroll bonuses, a press/CMS module, and moderation tooling while maintaining strict PHP 5.3 compatibility as a hard production constraint.

I’m also building an AI receptionist SaaS for beauty salons using Python, FastAPI, aiogram, and RAG on PostgreSQL + pgvector (with GigaChat API), alongside delivering turnkey commercial websites. Separately, I work in reverse engineering (x86 disassembly and extending decompiled Java applications) and I’m a heavy, disciplined user of AI-assisted development workflows (Claude Code), shipping faster than a typical solo developer.
