Freelancer Overview

With over 13 years of experience in Progress OpenEdge development, coupled with my current focus on expanding my skill set in data analytics, generative AI, and front-end development, I bring a unique perspective that bridges legacy systems with cutting-edge technologies—a combination I believe aligns well with the innovative work being done at your company. In my recent internship at Refonte Technologies, I am gaining hands-on experience in data analysis, visualization, and reporting using tools like Python, TensorFlow, PyTorch, and Jupyter Notebooks. This exposure has deepened my understanding of how high-quality annotated data serves as the foundation for training robust machine learning models. Additionally, my background in software development and database management equips me with a meticulous eye for detail, ensuring accuracy and consistency in annotation tasks—qualities essential for delivering reliable datasets. While my career has been rooted in developing and maintaining complex database applications, I have consistently demonstrated the ability to adapt to new challenges and technologies.
