About Me
I’m a Data Analyst with a passion for transforming raw data into actionable insights that drive smarter decisions. With experience in software development, customer support, and interpretation, I bring a unique perspective to my work, having gained valuable knowledge in industries like finance, health and auto insurance, and healthcare.
My main focus is helping businesses understand their data by uncovering trends, improving processes, and creating reports and visualizations that tell a clear story. I use tools such as SQL, Python (Pandas, NumPy), Excel, and Tableau to analyze, clean, and visualize data—turning complex information into easy-to-understand insights.
On this website, you’ll find a collection of my projects that showcase my skills in data analysis and storytelling with data. If you're interested in learning more or discussing potential opportunities, I’d love to connect! Feel free to reach out via the contact information on this page or connect with me on LinkedIn.

Experience
Data Analyst - Crumina
I work with a client in the automotive industry, helping them use data analytics to choose and sell the right vehicles. My job starts with collecting data from external APIs and organizing it into structured databases using Python. After that, I analyze the data with SQL and Excel to uncover market trends and understand what’s driving demand. I use the insights from my analysis to help the client make smarter decisions about which cars to sell based on what’s popular and what the market needs. On top of that, I help improve their inventory management and purchasing strategies to increase their profits.
Front-End Developer - SoftServe
At SoftServe, I worked on a project for a global company that sells natural food supplements across three continents, where our team built an e-commerce marketplace to showcase and sell their products. I played a key role in designing and developing user-friendly components that improved website functionality and user experience. Throughout the project, I collaborated with the team to address performance issues, enhance the app’s reliability, and meet deadlines. One of my proudest achievements was contributing to a UI component that helped boost the client's revenue by 15%.
Front-End Developer - Upwork
I worked on a project for a client that involved transforming Photoshop designs into responsive and visually engaging HTML template. I developed modular templates that were adaptable, easy to update and reuse, giving the client flexibility for future customizations. The template became a hit, contributing to a 20% increase in revenue for the client through multiple sales. https://themeforest.net/item/cryptoki-html-template-for-nft-and-digital-marketplace/34741893
