Who am I?

Backend with character, a pinch of ML, and a passion for stories.

I write code that feels both practical and a little playful. Backend services, bots that actually help people, and performance‑sensitive modules are my day-to-day. When the clock is free I craft micro‑stories, small technical notes, and experimental projects to learn something new — sometimes useful, sometimes weird, always instructive. I combine high-level productivity (Python, TS) with low-level control (C++, Rust, Cython) and enjoy gluing everything together via APIs and lightweight ML.

ML & APIs

Hands-on with the OpenAI API and other model APIs; I integrate model inference into real services. Fine-tuning, prompt engineering, and building efficient inference pipelines. Extensive work with platform APIs: Telegram Bot API, Discord API, REST & WebSocket integrations.

DevOps & Admin

Production admin for Linux & Windows servers: deployments, backups, monitoring, incident response. Docker, CI/CD (GitHub Actions), nginx, systemd, automation scripts. Reliable pipelines with Postgres, Redis, RabbitMQ, Cassandra when needed.

Notable Experience

Production Telegram and Discord bots, webhook infrastructure, and automation tools. Performance improvements combining Python + Cython; systems code in C++ and Rust. SSR and web features with Next.js; Vue 3 & Nuxt projects. Deployed fine‑tuned models to services handling real users.

How I Work

I favor pragmatic, testable solutions. Fast prototypes → validate → harden for production. And sometimes I build weird side projects just for the joy of learning.

My Story

How letters became sound, and code became the way

Curiosity

It all started with a simple question: "How does this work?". First experiments with code, the magic of turning symbols into living interfaces. It wasn't just a hobby, but the discovery of a new world where logic meets art.

C++ & ASM → Python → Rust

A journey from low-level C++ and Assembly, where every byte counts, through the flexibility of Python to the reliability of Rust. I learned to value memory control and type safety, choosing the tool for the task, not the other way around.

Olympiads and Club

Olympiads tempered my character, and leading the IT club taught me responsibility. Sharing knowledge turned out to be as exciting as gaining it. We are building a community where technology brings people together.

T-Bank Education

Participating in the T-Bank "Algorithms and Data Structures" project was a turning point. Deep diving into theory, solving complex problems, and working with mentors allowed me to reach a new level of engineering thinking.

Achievements

From simple scripts to complex GUI applications and Telegram bots with thousands of users. My projects don't just live in repositories; they bring real value. Every error is a lesson, every line of code is a step forward.

Active Growth

The IT world never stands still, and neither do I. Actively learning modern Web, practicing technical translations, and broadening my horizons. My goal is to become a T-shaped specialist capable of solving any challenge.

Why these projects?

Each project solves a real problem. I believe: the best code is the one that benefits people. My repositories are a mix of bots, integration tools, ML microservices, and performance experiments. Look at my pinned repos or write to me — I'm always open to collabs and ready for a guided tour of my code.
