I am here to be your guide in Full Stack development. For years I've been developing apps for FinTech, E-commerce, AdTech, E-learning, IoT, Beauty Industry and Social Media and have extensive experience in overcoming challenges that appear in the development processes. My skills are the following: ?????????????????????? ??????????????????: Java, PHP, Python While working on the projects I faced various challenges and successfully overcame them. For example, working with one Social Media company, I had to integrate new paywall without previous subscriptions and loss of the users' loyalty. So I developed the new paywall and connected it to the core via API. After that I removed the old one. Now a counter tracks the number of the articles, which users have already read and displays a notification when the limit is reached. The unsubscribed users can read only a section of the article. This was only one case from my development experience. If you need intellectual development based on the world best practices, I’m the right choice.
