Hi, I am a full-stack developer with 10 years of experience. I love the API-first paradigm with JS frameworks like React.js, Angular.js, or Vue.js on the frontend, and PHP, Node.js, or Python for the backend for complex interface apps. 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.
