About

I am a results-driven Backend Developer with 5+ years of experience architecting scalable PHP and Laravel applications for high-traffic production environments. I design REST APIs, optimize MySQL performance, and automate workflows that save time and reduce manual work. I have integrated 5+ enterprise APIs (OpenAI GPT-4, Google, Meta, YouTube, SpinnerChief) serving thousands of daily users.

I thrive in cross-functional teams, participate in code reviews, and mentor junior developers. I am proficient with SOLID principles, design patterns, and Agile methodologies, and I enjoy turning complex requirements into reliable, scalable software.
