I had the pleasure of working with Rafi on two projects during his time at ACS Solutions, and I can confidently say that he is an exceptional data professional. Despite being a recent graduate, Rafi quickly mastered new tools and concepts, demonstrating proficiency in SQL, Snowflake, and AWS services. He leveraged his expertise to build robust applications using Python, demonstrating a deep understanding of data warehousing, ETL, and database management. Rafi is an excellent problem solver with strong reasoning skills, and I have no doubt that he would be a valuable asset to any data project or organization.

I had the pleasure of working with Rafi during his internship at our company, and I was consistently impressed by his technical abilities and enthusiasm for his work. Rafi consistently demonstrated a strong aptitude for problem-solving and was always eager to take on new challenges. He was a valuable asset to our team, and his contributions were invaluable. One of the things that stood out to me the most about Rafi was his technical soundness. He had a strong grasp on the technologies we were using, and he was able to apply this knowledge to effectively troubleshoot and resolve any issues that arose. In addition to his technical skills, Rafi was a pleasure to work with. He was proactive, reliable, and always willing to lend a helping hand. He brought a positive attitude to the team and was a joy to be around. I highly recommend Rafi for any opportunity that he may pursue. He has the skills, attitude, and work ethic to excel in any role, and I have no doubt that he will make a valuable contribution to any team.
