I help businesses turn messy data into clear, actionable insights using Power BI, SQL, and Python. Whether you need an interactive dashboard, a market trends report, or cleaned-up datasets, I make data work for your goals, not the other way around. Along the way, I’ve studied physics, bioinformatics, economics, and business psychology. That scenic route taught me how to juggle numbers and people, and how to connect the dots between data, behavior, and strategy. My background allows me to approach data with both analytical depth and real-world business awareness. I specialize in data visualization using Power BI, Excel, and Tableau, and I’m comfortable working with structured and unstructured data using SQL, Python, and pandas. I’ve contributed to projects involving business analytics, market research, data storytelling, and performance reporting. I’m certified in Data Science by IBM and have also trained in management consulting methods to better align insights with business outcomes. I regularly use AI tools like ChatGPT to accelerate workflows, enhance research, and improve clarity in communication. These tools help me work faster and smarter, and keep your project moving forward. If you need sharp analysis, clean visuals, or thoughtful writing rooted in data, send me a message and let’s get started. I usually reply within a few minutes.
