About
PHP development
and production support
I work on commercial PHP projects, with a focus on 1C-Bitrix, e-commerce and API integrations.
I build catalog and cart APIs, work with stock and product variants, and diagnose problems in production.
I also maintain existing PHP code and make changes that your team can review.
