Vadim-Khristenko/README.md

Oh, hi! 👋 I'm Vadim Khristenko

Developer • Builder of fast systems, bots, websites, and odd little experiments

Also author of short books, novellas and fanfics — I like telling tiny stories between commits.

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.

Quick snapshot

  • 🔭 Currently: building Telegram Bot VIA (https://t.me/VIA_by_VOLT_BOT) and Telegram Bot Sveta (https://t.me/VIA_by_VOLT).
  • 💬 Ask me about: Python/Cython, C++/Rust, bot development (Telegram/Discord), OpenAI integrations, and model fine‑tuning.
  • 📫 Email: [email protected]
  • 🌱 Playtime: web games, small ML experiments, and performance tuning.

Core skills (badges)

Next.js React Vue 3 Nuxt

Python C++ Rust Java Kotlin JavaScript TypeScript

Postgres MySQL MongoDB Redis Cassandra SQLite

OpenAI Telegram Discord Docker GitHub Actions Linux Windows


Machine learning & 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 & administration

  • 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 (short)

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


Projects & experiments

Small focused repositories: bots, integration tools, ML microservices, and performance experiments. Look at pinned repos or ask for a guided tour.
