About Me

Hello, I'm HimaI work with data to understand what’s really going on behind the numbers and to help teams make better decisions. Over the past 4+ years, I’ve worked across tech, fintech, HR and education, using data, machine learning and AI to solve practical business problems and improve how things work.I use tools like Python, SQL, Power BI, SAS Viya and many more to handle data, built models, spot patterns, and present insights in a way that makes sense to non-technical people. My experience includes business intelligence, data warehousing, automation, sentiment analysis, and mapping complex systems basically anything to do with analytics.I’ve gained professional experience and work ethic at places like Walmart Global Tech and UNSW, where I worked closely with stakeholders, researchers and business teams. I enjoy fast-moving environments and figuring things out when there isn’t a clear answer yet.Right now I'm building on cloud analytics skills however, on weekends, you’ll usually find me at the beach or Sydney markets away from screen time for some fresh air!
