    Highly experienced freelancer with over 10 years experience delivering applications in a variety of programming languages. I can easily and quickly adapt to new languages, technologies and frameworks due to my strong grasp of computer science fundamentals. Languages and frameworks are just tools that I need to achieve the goals set by my clients. I am very proficient in Python (using Django and Flask), C, C# (using ASP.NET) and Java (using Spring, Spring Boot) on the backend languages side and an expert in algorithms and data structures as well, having participated in various computing contests. This allows me to write optimized applications (especially web applications and APIs) that will scale to many users and require minimal rewrites as your needs grow. On the frontend site, I have over 5 years experience working with JavaScript, Angular and React to develop various web applications from scratch and also to maintain existing ones. I have worked with the most popular database solutions: SQL - MySQL, PostgreSQL, MS SQL and also with non-relational databases such as MongoDB and Firebase Firestore. I have a PhD in machine learning so I am also very familiar with the latest advances in the increasingly popular field of AI and machine learning and I can therefore offer high quality work in this area as well, especially in Tensorflow and Keras. My clients' full satisfaction is what I pride myself on the most and I will stop at nothing to deliver this.
