About Me
Hello! I'm Hima. A data-driven problem solver with a passion for transforming complex datasets into strategic insights and driving business impact through analytics. My journey in the world of data spans over 4 years across global tech, fintech, and education sectors, where I've developed a keen ability to extract meaningful patterns and actionable intelligence from diverse datasets. This fascination has driven me to master tools like Python, SQL, Power BI, and SAS Viya turning raw information into compelling business narratives.With experience at organizations like Walmart Global Technology and UNSW, I've developed my analytical skills in real-world environments, leading cross-functional teams and implementing automation solutions that tangibly improved operational efficiency. My work has ranged from creating interactive dashboards and resolving RPA bot failures to conducting sentiment analysis and mapping payment technology infrastructures.I thrive in dynamic environments where I can apply my analytical mindset to solve complex business problems. My combination of technical expertise and business understanding allows me to bridge the gap between data and decision-making, translating numbers into narratives that drive strategic action.
