About

I work at the intersection of enterprise application engineering, CRM customization, backend-heavy full-stack development, and automation-led product improvement. My core work has centered on building maintainable systems that support complex business flows without sacrificing reliability or clarity.

My background includes PHP, Yii1.1, Laravel, MySQL, JavaScript, AWS, Bedrock, and n8n, along with AI-assisted development tools like Cursor and Codex.
