PHP Developer, 5+ years experience

PHP Developer with 5 years of commercial experience in eCommerce, eMarketing, and iGaming, working in teams ranging from 2 to 30 members, both remotely and on-site. I have nearly 2 years of team-leading experience. I have built web applications from scratch: starting from product owners concepts to automated releases, with high coverage of unit tests, integrated analytics, and CI/CD. I have successfully renewed legacy projects, providing technical leadership and support. Additionally, over the last 3+ years, I have worked on high-load applications, successfully developed and maintained by the teams I was part of. My most recent experience includes query optimization, sharding, load balancing, creating microservices and maintaining large applications on both the backend and frontend as a full-stack developer.
