Bio

I am a senior back-end PHP developer with 22+ years of experience in web development and more than a decade of focused work within the WordPress ecosystem. As the founder of INFINITUM FORM®, I have built a wide range of custom solutions, including public plugins such as Geo Controller, Transliterator, Easy Auto Reload, Push Notification FCM, Registar Nestalih and Kopa QR. My work is centered on performance, security, API integrations and solving complex technical challenges for high-traffic and data-driven WordPress environments.

I actively contribute to the community through plugin development, code improvements, API integrations and collaboration with other developers. Over the years, I have shared knowledge at local WordPress meetups and led training programs for new developers, focusing on practical, real-world WordPress architecture and modern PHP standards.

My experience includes custom plugin development, advanced integrations, WooCommerce extensions, REST API design, and performance optimization for enterprise and large-scale platforms. I continue to build tools, improve existing solutions and support the growth of the wider WordPress community.

If you are interested in collaboration or improving complex WordPress systems, feel free to connect.

WordPress Origin Story

My WordPress story began in 2011, when I needed a design that no existing theme could provide. Instead of compromising, I decided to build the theme myself. That first project sparked my interest in WordPress development and quickly grew into a long-term focus on creating both custom themes and plugins.

Over the years, I have developed more than 200 plugins and around 50 themes, most of them for private clients and custom projects, as well as several that I’ve published on wordpress.org. This work naturally led me toward performance optimization, backend architecture, advanced integrations and solving complex problems inside the WordPress environment.

Beyond development, I have been involved in the community through meetups, knowledge sharing and private training for beginners. WordPress has been a continuous source of learning, growth and collaboration, and it remains a core part of my professional journey.
