Hi, I'm Mark, a Full Stack Web Developer from Philippines.

Professional Summary

 I am a Senior Full Stack Web Developer with 14+ years of experience designing, building, and optimizing scalable web platforms and backend systems. My background spans PHP ecosystems, modern JavaScript frameworks, WordPress engineering, and high-performance Linux infrastructure. 

I work across backend architecture, APIs, frontend delivery, performance tuning, and operational hardening. Much of my recent work involves solving practical production problems such as slow queries, brittle integrations, overloaded infrastructure, and codebases that need to move faster without becoming harder to maintain. 

More recently, I have been integrating AI-assisted development workflows into day-to-day engineering work using tools such as OpenAI Codex, Claude Code, and OpenClaw. I use these tools to automate repetitive tasks, speed up debugging and refactoring, and improve delivery throughput while maintaining code quality.
