Hi, I am a full-stack developer with 10 years of PHP (Laravel, Symfony) experience. I have acted as software architect and technical lead on a number of projects. I use PHP, MySQL, HTML5, CSS3, JavaScript, AJAX, GIT on a daily basis. Over the last 6 months I have implemented a large project - GraphQL API for the Hedera network. It allows to make convenient human-readable queries on various events from the network. This also includes a bunch of related projects - SDK, client dashboard, analytics system, etc. I've developed a mobile app that shows the best sales offers nearby on an interactive map. Here are some other examples of my past projects: - ScopeSports - NFT-marketplace and social network with paid access to exclusive content and direct communication with sports athletes. The non-blockchain functionality is a hybrid of Facebook and Discord. Chats, posts with videos or pictures, comments, each athlete and his audience have their own private fan club. - Jamble - a German Tinder-like dating app. The service has a sophisticated matching algorithm based on profile preferences and matching quizzes. Voice/video chats and personal content sharing are available for the premium membership plan. I have a pretty decent amount of projects in my portfolio. I am happy to tell more during a video call.
