About Me

Quality Assurance Engineer| Data Analytics & Data Science

Developing With a Passion While Exploring The World.

My career started in web development, but I quickly found myself drawn to the investigative side of technology understanding how systems behave, where things break, and how products can work better for the people using them. Over the past three years, I’ve worked in startup technology environments across web, mobile, and IoT platforms, building experience in quality assurance, automation, and product testing. My work has involved digging into application behavior, validating APIs and data flows, and collaborating closely with engineers to help teams release reliable digital products.

Along the way, I realized that many of the questions I was asking while testing software were really data questions. That curiosity led me to complete an MSc in Data Science and Analytics, where I graduated with Distinction and developed deeper skills in machine learning, statistical analysis, data mining, and database management. Today, I enjoy exploring the intersection of software systems and data understanding how products generate data and using that information to uncover insights that can improve performance and decision making.

I’m currently exploring opportunities in data analytics and technical data roles where my background in software systems, automation, and data science can add value. Always happy to connect with people working in data, analytics, and product engineering or to discuss opportunities where data can help teams build smarter, more reliable products.
