🖥️ Projects
ALT RPM Set Version Research
Research into ALT Linux RPM's encoded symbol sets and dependency comparison. The project covers C implementation work, hashing, compatibility testing, sanitizer checks, and benchmarks against realistic RPM/APT workflows.
Personal Infrastructure Automation
Ansible playbooks for automating Linux servers and repeatable administration. My broader infrastructure work includes multi-node K3s clusters, container deployment, ingress and ServiceLB networking, TLS lifecycle automation, and remote troubleshooting.
For example, Gitea Instance
nexus-sync
A client-server system for centrally managing computers and dispatching approved commands. Built with FastAPI and SQLAlchemy, with a CLI, YAML-configured clients, systemd units, standalone builds, tests, type checks, and CI packaging.
Pomodoro
A customizable browser-based Pomodoro timer and clock built with React, TypeScript, and Vite. GitHub Actions tests and packages it as an unprivileged multi-architecture container published to GHCR. Aviable on pom.krosh.dev
Network Diagrams Tool
A Python tool for building and visualizing network topologies, developed for networking and infrastructure coursework at CMC MSU.
Marzban Telegram VPN Bot
A containerized Python Telegram bot that integrates with the Marzban API, manages one-time invitations and user lifecycle, and persists local state in SQLite.
Syncing Spotify with Telegram Bio
A script that syncs the playing track from spotify in the background with the Bio column in the user's telegram.
