@halynapirko

PHP Backend Developer at SKIndustries who optimized SQL and indexing to cut page load time from ~3 seconds to ~1.

At SKIndustries, I designed and implemented RESTful APIs for a digital freight transportation and logistics platform, covering 40+ endpoints across 14 core business entities with PHP and Laravel.

I improved page load time from approximately 3 seconds to approximately 1 second through SQL query optimization and indexing. I also refactored legacy code and integrated third-party services.

At SoftSprint, I developed and maintained a custom PrestaShop module for automated XML product imports and financial management modules for payment and loan processing. I also integrated backend services with frontend components using AJAX and JavaScript.
