About

I am currently a third year undergraduate student at Maharaja Agrasen Institute of Technology (MAIT), Delhi, pursuing a Bachelor of Science in Computer Science and Engineering with a specialization in Artificial Intelligence and Machine Learning. My passion lies in the field of coding, where I spend a significant part of my time learning and adopting new technologies. My approach to problem solving is deeply rooted in my love of coding, and I actively improve my skills by solving challenges on platforms like LeetCode and CodeStudio, primarily using the C++ programming language. I am also in the process of expanding my knowledge in the field of full-stack web development. React.Js | JavaScript | Tailwind CSS | Next.Js | MERN Stack: MongoDB, Express.Js, React.Js, Node.Js. At the same time, I also embarked on a journey into Data Science, which aligns with my academic pursuits in my B.Tech program. Essentially, I pursue multiple avenues of learning and growth and strive to excel in each through my unwavering commitment and enthusiasm. Your consideration of my journey would be greatly appreciated.

> As an SDE Intern at Brivio, I engineered a scalable, low-latency, AI-powered interview voice agent. This involved replacing Vapi with LiveKit to achieve significant reduction in monthly infrastructure costs.
> Worked with Livekit, a low-latency SFU-based media pipeline, orchestrated the STT-LLM-TTS flow using Deepgram, OpenAI, and 11-Labs, and optimized voice activity detection with Silero VAD.
> Developed robust, responsive full-stack features, which included integrating a code editor with the AI agent, creating feedback-system endpoints, and building responsive UIs in React.js/Next.js using ShadCN components with pagination and client-side filtering.
> Finally, I automated the upload of interview recordings from Vapi's S3 to Brivio's S3 for backup purposes using a Node.js microservice.

> As a Full-Stack Developer & LLM Engineer Intern, my core responsibilities were designing and implementing features from scratch for which I had to juggle between frontend and backend. The product was in Next.Js and TypeScript with authentication in Next-Backend using Next-Auth and the rest of the logic in a separate express app with DB as MongoDB. I used Prisma as ODM in Next and mongoose in the express backend. Additionally, I got hands-on experience with how Kubernetes, Docker, Helm, Bitnami, and Azure's AKS function.
> As an LLM engineer, I integrated a multi-LLM model, akin to a custom LangChain, to generate recommendations paired with a scoring engine that evaluates LLMs based on custom parameters to identify the top-performing model and a trained chatbot.
> Both lead to making the core offering of the startup a reality.
