I build scalable PHP backend platforms for high-load production systems.

Message

I'm currently building and optimizing backend systems at Softgamings, supporting an iGaming platform serving 100M+ players and 50B+ annual transactions. I created a tournament-testing backoffice that cut manual validation by 70% and improved Laravel API response times by 30–40% during peak activity.

Across Webhost1, EPAM, EffectiveSoft, and Siteguarding, I've delivered PHP services for hosting, enterprise e-commerce, and security remediation. My work spans high-load APIs, MySQL optimization, payment workflows, background jobs, real-time chat, and production reliability for platforms serving millions of users and hundreds of thousands of websites.
