Omar Francisco A.

AWS DevOps engineer and Linux server administrator for web apps. I deploy, secure, migrate, and maintain Laravel, PHP, Node.js, Next.js, and Python applications on Linux VPS and AWS, so your app stays fast, secure, and online. I spent 10 years as a full-stack web developer before moving into DevOps and server administration. Most sysadmins don’t read application code, and most developers avoid servers. I work on both, so I can trace a problem from the code to the server configuration and fix it at the source. WHAT I DO • Linux VPS and AWS setup: EC2, S3, RDS, Nginx or Apache, SSL certificates, firewalls, and server hardening • CI/CD and deployment automation: GitHub Actions, Docker, zero-downtime deployments • Server and website migration: moving apps, files, and MySQL/PostgreSQL databases to a new server or to AWS with minimal downtime • Web application security: security audits and vulnerability assessments for web apps, including AI-built and “vibe-coded” apps • AI app deployment: hosting and securing AI-powered apps and automations (self-hosted LLMs, n8n, vector databases) • Ongoing server maintenance: updates, backups, system monitoring, and uptime alerts • DNS, domain, and email setup: Cloudflare, domain routing, and email deliverability (SPF, DKIM, DMARC) WHY CLIENTS WORK WITH ME • I understand your application, not just your server • Clear written plan before I touch anything in production • Everything documented, so you’re never locked in to me TECH STACK Linux (Ubuntu, Debian) · AWS · Docker · GitHub Actions · Nginx · Apache · Laravel · PHP · Node.js · Next.js · Python · MySQL · PostgreSQL · Redis · Cloudflare Send me your stack and what’s going wrong. I’ll reply with a clear plan and a fixed price.
