I've had the unique privilege of working with Stella at Teltech, and witnessed firsthand the immense growth she has gone through. Developing from Data Analyst to two more echelons up into a full-fledged Data Scientist, she has demonstrated great proficiency in the realm of Machine Learning and ELT processing, having built upon the fundamentals of her masterful SQL and Python skills, to become an invaluable asset to both the company and the team. It is through these same high decorations that I can confidently say Stella is an expert in her craft, and the magnitude of talent that she brings to any company is intangible.

I worked with Stella in the same company, sometimes on the same project and sometimes on my own project asking her for her point of view. She is very curious, detail oriented, a great thinker and always willing to help out and get involved; which makes her an exceptional data analyst. She has a passion for achieving highest goals and best solutions possible, and equipped with necessary skills to achieve them (solid understanding of math, statistics, programming languages and most importantly the ability to apply them to the real-world problems) . She aspire to become an excellent data scientist with more Machine Learning/AI knowledge. She is a fast learning and is developing skills necessary to achieve great results. I am very pleased and will cherish the moments I worked with Stella
