About Me

01

My name is Karan Rajesh Talwalkar, and I am an AI Engineer and Data Scientist currently working at QualityKiosk Technologies. My passion lies in building intelligent, scalable, and impactful AI systems that bridge the gap between cutting-edge research and real-world applications. I have completed my B.Tech in Artificial Intelligence & Data Science from NMIMS University, and I am driven by a constant curiosity to explore how AI can solve meaningful problems across industries.

I have a deep foundational understanding of machine learning, deep learning, computer vision, and advanced signal processing. My work includes building a comprehensive AI-powered vitals detection system capable of estimating heart rate, respiratory rate, SpO₂, BMI, age, gender, stress, and more using just a 20-second facial video. I have developed robust systems for deepfake detection, mental health analysis using foundational LLMs, rPPG-based pipelines, and multimodal AI architectures. I have also worked extensively with Retrieval-Augmented Generation (RAG) systems—designing intelligent, context-aware pipelines that improve accuracy, reliability, and scalability of LLM-based applications.

Alongside my AI expertise, I have hands-on experience in full-stack and frontend development using React, Tailwind CSS, JavaScript, Flutter, Dart, and Firebase. This enables me to build powerful, user-friendly applications that seamlessly integrate advanced AI models with clean and intuitive interfaces.

I am always seeking opportunities to apply my knowledge, collaborate on innovative projects, and contribute to impactful AI-driven initiatives. I believe my strong technical foundation, problem-solving mindset, and dedication to learning allow me to deliver solutions that are both efficient and meaningful. Whether it's AI research, intelligent automation, RAG pipelines, or building immersive user interfaces, I aim to bring precision, creativity, and real-world value to every project I work on.
