About Me

I’m passionate about turning data into insights that drive smarter decisions. Skilled in Python, R, SQL, Power BI, and Tableau, I specialize in building dashboards, optimizing ETL pipelines, and integrating data across systems. With 5+ years of experience across data analytics, integration, and full-stack development, I enjoy solving complex problems, streamlining workflows, and creating tools that make data more accessible. My background spans working with cloud platforms, SAP integration (PO/CPI), and statistical modeling, giving me a strong foundation to bridge both technical and business needs.

Outside of work, I’m a determined and creative individual who enjoys hands-on projects that require patience, precision, and the ability to transform raw ideas into meaningful outcomes - qualities I carry into my professional work as well.
