I've built machine learning systems for restaurant rating prediction, recommendation, cuisine classification, and geographic analysis as a Machine Learning Summer Intern at Cognifyz Technologies. My work spans NLP, computer vision, IoT, cybersecurity, and algorithmic trading applications.

For my final-year project, I designed a memory-augmented long-form video QA system using LLMs, VLMs, OpenCV, ffmpeg, FAISS, NanoVectorDB, and knowledge graphs, reducing cost by 59.7% and latency by 20.1% over the baseline. I also build RAG chatbots, multimodal medical-imaging frameworks, IoT automation systems, and deep-learning malware detection models.
