TiSpace is a leading career accelerator combine advanced technology and tailored skills to reach career goals in record time. As a researcher, I developing algorithms using various technologies and tools for NLP, ML, and DP. I developed several algorithms using the NLTK with Python and Word2Vec to analyze and match job descriptions and candidate resumes to improve the hiring process for both sides. Implement named entity recognition (NER) and sentiment analysis has also been instrumental in developing algorithms that accurately identify and match candidates based on their skills. I building NN on TensorFlow for predicting candidate-job fit and optimizing job recommendations. Using transfer learning and prompt technique to calibrate LLM Transformer for the task Show less

DSP-IP Deep Learning Bootcamp and Internship
-
2021 - 2022
During my 6-month internship, I worked extensively with cutting-edge technologies in computer vision while handling client data. My responsibilities included preprocessing and cleaning large datasets, developing and implementing advanced computer vision algorithms (YOLO, Faster R-CNN,MASK-CNN& U-NET), evaluating and optimizing models, and collaborating closely with the client to ensure their requirements were met. Throughout the internship, I applied my knowledge of computer vision concepts, utilized programming languages such as Python and TensorFlow, and leveraged deep learning frameworks to tackle complex problems. Working with real-world datasets allowed me to gain practical experience and effectively translate client needs into impactful solutions. Show less

2018 - 2018
As a research assistant, I played a critical role in the successful execution of various studies. I was responsible for managing and organizing the research days, including summarizing and studying topics for my direct boss and other staff members. I also contributed to the development of new leads for studies. In addition, I utilized my skills in R and Matlab to modify and build experiments to ensure accurate and reliable results. I then analyzed the data using specialized scripts or hand-on statistics using SPSS, depending on the data type and the research question. My ability to consider the research question and the manner in which the data was acquired allowed me to provide insightful analysis and interpretation of the results Show less
