• Developed a robust pipeline for real-time audio data processing, which involved parsing data from web sockets, connecting parsed data to LLM, and delivering audio and text responses to the corresponding client. This process significantly improved the efficiency and responsiveness of our client communication system. • Implemented a Short-Term Memory system for chat storage, enhancing the system’s ability to recall and process information. Additionally, utilized Milvus, a powerful open-source vector database, for efficient vector storage, contributing to the overall performance and scalability of the system.

About

“If intelligence is a cake, the bulk of the cake is unsupervised learning.” — Yann LeCun I care about the bulk of the cake and the infrastructure that bakes it. I work at the intersection of AI and Backend Engineering, turning research into systems that scale. My focus: LLMs, real-time data pipelines, Agentic AI and GenAI architectures built for production. 🔗 Open to connecting, let’s build something.
