Backend & cloud engineer — C++, Python, Linux. 8+ years building backend systems.
I build backend services and low-level tools, keep my infrastructure as code, and occasionally wear the DevOps / SRE hat.
- filecast — file transfer over LAN via UDP broadcast with packet-loss recovery (C++, Linux/macOS/Windows). Installable via Homebrew.
- geo-utils-cpp — header-only C++17 library for lat/lng geometry: distance, bearing, area, point-in-polygon. Packaged for vcpkg and xmake.
- C-P2P-Chat — decentralized P2P chat in pure C: UDP, non-blocking I/O, peer auto-discovery, ncurses TUI.
- RakLib-Proxy — proxying UDP packets inside a Linux kernel module.
- gistrec-cloud/infra — my server fleet as code: Ansible (SSH hardening, nftables + fail2ban, nginx, netdata) and Terraform (Cloudflare DNS, AWS, Yandex Cloud).
- nginx-scanner-trap — turns an nginx box
into a honeypot: the first probe of
/.envor/.gitgets the scanner banned on all ports via fail2ban + nftables.
