About

Professional summary

I am a Senior PHP Developer with 8+ years of commercial experience building and maintaining web products with PHP 8+, Laravel, and WordPress/WooCommerce.

I specialize in scalable e-commerce systems, REST API integrations, and performance optimization. In my recent work, I have focused on high-traffic applications, MySQL query tuning, Redis caching, and reliable backend architecture.

I have experience delivering products end to end, from design and implementation through deployment and operations. I work with Docker, CI/CD pipelines, Linux servers, and production monitoring to keep systems stable and maintainable.

I am also the author and maintainer of a public WooCommerce plugin with thousands of active installations, and I founded a SaaS product that I designed, built, and operate on my own.

I enjoy working on practical engineering problems, improving code quality, and collaborating with product and client teams. I have experience with Agile workflows, testing, and modern development tooling.

I am open to opportunities where I can contribute as a strong backend engineer, especially in PHP/Laravel, WordPress, and e-commerce-focused products.
