    Chaitanya is one of the finest engineers I’ve worked with. Besides the fact that he is a very competent machine learning engineer, his ability to calmly endure any problem statement and take it to the finish line really shines. We worked together in Swiggy and collaborated on setting up the ML inference pipeline for PyTorch models. His contributions in both the LLD and execution has been incredible. I look forward to working with him in the future, and I’m sure that whichever organization he joins would greatly benefit from his talents.

    I’ve had the pleasure of working with Chaitanya for almost 1 and a half years at Stylumia, where he has been a valuable member of our computer vision team. Chaitanya is a highly skilled computer vision engineer with a strong track record of success. He has solved complex problems at an industry scale, including Image feature extraction and classification. He is also an excellent problem solver, and he is always able to find creative and innovative solutions to complex problems. In addition to his research skills, Chaitanya is also an excellent communicator. He is able to clearly explain complex technical concepts to both technical and non-technical audiences. He has presented quite a few research papers to the entire company and helped build use-cases on top of the research papers. I have no doubt that Chaitanya would be an asset to both research teams and application teams.
