What I'm looking for

I'm looking to build reliable Laravel backend systems, REST APIs, and scalable e-commerce or B2B products while growing through enterprise architecture, clean code, and collaborative engineering work.

I'm building AURA HR Portal, a secure multi-tenant B2B corporate portal for commercial deployment, with Laravel 13, client data isolation, transaction-safe operations, and role-based access control.

At Bazarbay, I developed backend services for marketplace price monitoring and dynamic repricing. I built internal APIs for vendor metrics and competitor tracking, reduced database overhead with Redis caching, and integrated UniSender and Green API messaging.

I also mentor junior PHP developers at Recursia School, reviewing assignments and helping students debug logic, profile applications, and fix queries.

My work includes high-load e-commerce and CMS platforms with REST APIs, asynchronous processing, RBAC, order management, moderation workflows, Docker environments, and GitLab CI/CD.
