What I'm looking for

I’m looking to build secure, high-availability backend systems and REST/GraphQL APIs in cloud-native teams—using PHP/AWS to reduce errors, automate workflows, and continuously improve system design, stability, and performance.

I’m a results-driven Software Engineer with 4+ years designing scalable backend systems, RESTful APIs, and cloud-native applications. I’ve built production-grade services with PHP (Laravel, Symfony, CodeIgniter) and strong database architecture, with measurable impact like reducing processing errors by 40% and achieving 99.9% application uptime.

In my Backend Systems work, I led maintenance and feature development of WPeMatico and premium add-ons, cutting support tickets by 25% through proactive bug fixes and UX improvements. I also engineered Facebook Graph API integrations for automatic content publishing and analytics, and shipped AI-powered content recommendation features that increased user engagement by 30%.

I’m known for system stability and automation—designing billing and transactional systems that automated ~90% of manual workflows using comprehensive backend validation frameworks and system controls. I contribute to open-source PHP and WordPress libraries, and I’m pursuing AWS Cloud Practitioner while exploring system design and microservices architecture.
