Projects

Lead Developer & System Administrator

Designed, built, and operate a production web platform serving 300+ students, running on a self-managed Debian 12 server. Led a security hardening initiative: isolated the Docker socket via a proxy, migrated all containers to run as non-root users, and performed a full production data migration. Built a Discord bot integration, an in-platform economy/cosmetics system, and public user profiles with custom-generated avatars.

Founder

Co-architected a full-stack monorepo (Turborepo, pnpm workspaces) with a Next.js frontend and a Nest.js API. Integrated an LLM-based recommendation engine to generate personalized gift suggestions. Set up GitLab CI/CD pipelines and Git hooks (Husky, lint-staged) to keep code quality consistent across the team.

Personal Project

Built an automated content pipeline using n8n: aggregates multiple RSS feeds, filters and selects articles via a locally-hosted LLM, and auto-publishes formatted news posts to a Telegram channel. Self-hosted an open-source LLM (Ollama) optimized to use native GPU acceleration rather than running in a container.

Freelance Developer

Replaced an outdated WordPress site for a freight company hauling cargo from China, Europe, and the CIS with its own fleet (refrigerated, tarpaulin, and low-bed trailers). Multilingual content is built at compile time — every language version is indexed and works without JavaScript. Built a custom static site generator in Node.js: Russian is the source language, English and Chinese are generated from a shared dictionary, and the build fails if a translation key is missing. The key feature is a blog the owner runs entirely through a Telegram bot: publishing, editing, deleting posts, and granting access to employees — while the site itself stays fully static (PHP only runs at publish time). The contact form is protected with a honeypot, IP-based rate limiting behind Cloudflare, and header-injection protection, plus compliance with Russia's 152-FZ data law. 118 automated tests across five suites, each written from a real bug (e.g. an invisible space silently breaking an SVG icon, or a year-long Cloudflare cache hiding content updates).

Freelance Developer

Client: RusTransAvto, an international freight carrier (China/Europe/CIS routes). The site had to be 100% static — zero external requests, instant load even on a poor connection. Problem: how does a non-technical owner publish blog posts without a CMS? Solution: a Telegram bot. He sends a photo and text, sees a preview, edits it in place, and publishes — the site build process takes the Russian text as the source and automatically generates EN/CN versions from a shared translation dictionary. The site stays fully static; a PHP script runs only at publish time to rebuild the relevant subpages. No database, no admin panel to learn, no CMS-typical attack surface — just a chat he uses every day.
