Running my own freelance practice covering full-stack development, DevOps, and security, managing everything from live production servers to custom software builds. I handle Linux server administration, deployment pipelines, and security hardening for real production infrastructure, alongside building custom applications and Minecraft server plugins from scratch in Java, Node.js, and React. Achievements/highlights (bullet options — pick a few, Fiverr usually allows a short list): - Architected and maintain a multi-server production hosting environment with automated failover, backups, and SSL management for live client websites - Built a custom Minecraft server plugin suite from scratch (46,000+ lines of Java) covering economy, GUI systems, territory claiming, and moderation tools - Developed full-stack web and mobile applications end to end, including database design, authentication, and deployment - Led security hardening and incident response for production systems handling real client and user data
