Hello there! I’m a Data Analyst with 4+ years of experience turning messy data into clear insights. I’ve worked with tools like Python, Hadoop, SQL, Power BI, AWS, and Azure to build dashboards, automate data pipelines, and support smart decision-making—mostly in finance and healthcare. I enjoy solving real-world problems with data and love making complex things simple and useful.ThanksSai Teja Makloor
