What I'm looking for

I seek roles where I can build scalable web systems, reduce technical debt, lead migrations/optimizations, and work in collaborative teams that value maintainability and measurable impact.

I am a Full Stack Developer with over 10 years in IT and 5+ years specializing in PHP, experienced in building scalable web applications and APIs using Laravel, Slim, CodeIgniter, and Yii.

I have led framework migrations, performance optimizations, and delivered end-to-end systems — notably reducing message dispatch time by 96% and enabling large-scale spreadsheet validation without memory overflow.

I combine backend expertise (service/repository patterns, RESTful APIs, Node.js) with frontend skills (JavaScript, jQuery, React, Blade) and strong infrastructure knowledge (Linux/Windows administration, Apache), focusing on maintainability, interoperability, and reducing technical debt.
