While I have not yet had direct experience with big data tools like Hadoop or Spark, I am eager to learn and work with them. During my internship at Exposys Data Labs, I gained foundational knowledge in data processing and encryption, which I believe will be beneficial when working with big data technologies. I am also familiar with cloud platforms conceptually and am keen to develop practical skills in this area. I am proactive in learning new tools and technologies, and I am confident that I can quickly adapt to using these big data tools effectively.
