At Payquad, I maintain and modernize a legacy PHP codebase, design APIs, optimize performance, and work extensively with payment systems. I also migrated an application to Angular and maintain a cross-platform application.
Across iTechArt (now Vention), Gauder, TaleBy, and PsychoAnalitik, I've delivered PHP and JavaScript solutions for international projects, Shopify workflows, information systems, and online payments. I've worked with Laravel, WordPress, MySQL, Angular, AWS, Docker, Elasticsearch, and Liquid.
I've also led PHP engineers through hiring, interviewing, mentoring, and performance reviews, and founded QuizPolaka.pl, an educational application using AI-generated quizzes, adaptive feedback, and progress tracking.
