Annadurai Ma

RHCE-certified engineer with 15+ years running Linux production servers, now building and hosting AI-enabled web applications, web portals and websites end to end. I use an AI-assisted development workflow built on Claude Code, Claude Cowork and Claude.ai Projects: requirements and specifications first, then architecture, build, testing, and a one-command Linux installer with systemd services, reverse proxy, database setup and health checks. Delivered AI knowledge portals with private local LLMs (RAG), document-approval workflows, n8n automations and engineering file viewers, deployed on Ubuntu servers.

Combines developer speed from AI tooling with the production discipline of a senior system administrator: uptime, backups, security hardening and clean handover documentation.
