I have plenty of experience in various positions: seller, creator of e-shop, technical support operator, chef of call-center department, business analytic, Power BI developer. At each position I managed to receive best results of all other my colleagues. I like to communicate with developers and process owners, I'm into gathering information from the mess of legacy data. It was in the past. Now I am just a guy who want to work and implement my experience and skills to the company with the hope to not go back to Russia. PS My previous manager described me: If you want something, but don't know what exactly - go ask Yuriy. Your stuff will be done with sticks and turd, but done! He thinks out of the box. If you want to see something, but you do not know what - Yuriy will help you find anomalies as well as regular statistics.

My expertise spans a range of domains, including financial analysis, data visualization, advanced data analysis, and statistical modeling. I am proud of my consistent ability to deliver actionable insights that drive tangible results. Driven by an unwavering work ethic, meticulous attention to detail, and exceptional communication skills, I am relentlessly dedicated to not only meeting but surpassing expectations. My pursuit of mastery in the dynamic realm of data and business analysis led me to undertake a rigorous MSc in Business Analytics at Dublin Business School, Ireland. This academic endeavor expanded my horizons, enhancing my capabilities to tackle intricate analytical challenges. Having further honed my skills, I transitioned to Spain—my second home—to continue contributing my expertise to the global business landscape.

    Hey there! I'm a software developer with extensive knowledge of C# and the .NET ecosystem I have also extensive SQL knowledge and have worked mainly with SQL Server and SQLite, but can work in other relational databases like Postgres and MySQL. I also have worked with non-relational databases, mainly MongoDB. Lately, I've been delving in some rather complex scenarios of SQL Server performance. In the realm of web development, I'm proficient with JS/TS and frameworks like Node and Next(React). My go-to frontend library is HTMX, complemented by a solid understanding of CSS, TailwindCSS, SCSS, and Material UI. Python is another tool in my belt, particularly for crafting APIs with Flask. But since I have a profound interest in trading and quant finance, I have started to learn machine learning and automation focused on this area Recently, I've been honing my skills in Go, exploring backend systems, microservices with GRPC, and even delving into blockchain projects.
