    Hello, I'm Hlieb! During my tenure at the university, I developed a profound interest in information technology, fuelled by an ambitious desire to simulate all phenomena in nature through computational means. This aspiration prompted me to pursue knowledge with zeal in both natural and computer sciences. With a solid educational foundation in Information Technology and an extensive career journey that started as a Senior Data Scientist, I've navigated my way through the complexities of data to emerge as a proficient AI developer and a knowledgeable full-stack developer. My academic background laid the groundwork for my expertise in core programming languages such as C++, C#, Java, Python, and JavaScript. In the professional realm, I've honed my skills in creating, maintaining, and innovating machine learning approaches, deeply engaging with data analysis, modelling, and visualisation to drive insightful outcomes. Tools like Python, Matlab, and R have been my companions in processing data, alongside hands-on experience in database design and management using SQL, MongoDB, and PySpark. The leap to AI development was a natural progression for me, fueled by my foundational skills in data science and a robust understanding of mathematics. This transition not only enhanced my capabilities in AI but also opened doors to integrating AI technologies with web projects. As a result, I've gained solid knowledge in full-stack development, particularly in technologies such as React, Django, RESTful API, and FastAPI. **Future Goals:** My journey doesn't stop here. I am on a continuous quest for growth, aiming to deepen my domain knowledge in risk analysis and leverage my data science skills for strategic business decision-making and accurate predictions. Additionally, I aspire to excel as a web developer, especially in developing AI-related web applications, blending innovative technology with practical solutions. Whether you're in need of an AI solution, deep data analysis, help in natural sciences or even a full-stack web application, I'm here to bring your vision to life with precision, expertise, and a touch of innovation. I am always ready for you. daha az
