About Me

My passion for technology began in grade school, when my mom enrolled me in computer lessons. I was instantly fascinated by how simple commands could create something useful. That early spark grew stronger through high school, where I spent hours exploring Visual Basic and experimenting with real-world problem solving. In college, I was introduced to Turbo C, and while my major was Mechatronics, I always gravitated toward computer-related subjects.

After graduation, my passion for computing and data was reignited in my role as a machine engineer. I saw firsthand how accurate data handling could improve production efficiency, and I became deeply involved in root cause analysis and predictive maintenance for 24/7 machinery. These experiences showed me how data could drive smarter decisions and operational impact.

For me, data analytics is the convergence of everything I've always loved — computers, programming, and meaningful data. It's where technical curiosity meets business value, and where I've found the most rewarding challenges.

Today, with a background in Software Engineering Technology focused on AI, and certifications in Power Platform and Power BI, I'm equipped to bring these skills into the workforce by designing data-driven systems that improve performance, reduce inefficiencies, and support strategic goals. While technology will always evolve, the intention remains the same: to create solutions that are purposeful, efficient, and impactful.

"Information is the oil of the 21st century, and analytics is the combustion engine."
— Peter Sondergaard, Senior Vice President and Global Head of Research at Gartner, Inc.
