What I'm looking for

I'm looking to build and own reliable backend systems for high-load products, working with PHP, Laravel, APIs, asynchronous processing, testing, and production operations.

I've built and maintained backend systems for high-load products for more than nine years. At 4RABET, I delivered up to 20 production tasks per week across payments, bonuses, and user management on a large-scale iGaming platform.

I troubleshoot legacy Laravel systems and distributed Kafka and RabbitMQ flows, build REST APIs, and support production ownership through PHPUnit testing, CI/CD, and Kibana monitoring. I work hands-on with PHP, Laravel, MySQL, Redis, Docker, and asynchronous processing.

On a greenfield crypto trading platform, I designed and delivered API endpoints for orders, wallets, and accounts from specification through production. I've also extended multi-market real estate products, architected Laravel applications from scratch, and optimized slow SQL queries.

I enjoy translating business requirements into practical backend specifications, delivering client projects end-to-end, and mentoring junior developers.
