About

As an experienced software engineer, I specialize in building scalable backend systems and integrating large language models (LLMs) with retrieval-augmented generation (RAG) frameworks to power intelligent, AI-driven applications. My expertise lies in designing distributed, stateless systems and deploying high-performance architectures that elevate user engagement and streamline complex workflows. I have successfully architected dynamic, context-aware LLM agents that deliver real-time responses, significantly improving user interactions. By leveraging tools like LangChain, Redis, and vector databases such as Qdrant, I ensure fast and reliable information retrieval while maintaining seamless session continuity. My passion is in pushing the boundaries of AI and backend systems. From designing ETL pipelines for embedding creation to developing fully automated AI testing bots, I focus on creating reliable and scalable systems that drive impact. With strong experience in cloud platforms like AWS, containerization with Docker, and orchestration with ECS, I am adept at delivering efficient solutions in fast-paced environments. Outside of my professional work, I am also a YouTuber with 1.2K+ subscribers, creating content related to MS in USA. Additionally, I am a footballer and have won the IML Soccer Championship 2022 at UC Riverside.
