About

I am an AI Systems & Backend Engineer focused on building real-world, low-latency intelligent systems that operate reliably in production-like environments. Currently working as an AI & Automation Intern, I develop real-time AI systems including: • Voice-based AI receptionist handling live calls using LLMs, streaming pipelines, and WebSockets • Tool-integrated LLM systems for structured and deterministic data retrieval • Document intelligence pipelines using OCR + NLP for transforming unstructured data My work focuses on end-to-end system design — from model integration to real-time communication, API orchestration, and deployment on cloud infrastructure (AWS EC2). Beyond AI systems, I am also building automation-driven products such as a WhatsApp Payment Reminder System designed for small businesses, enabling simple QR/UPI-based payment flows without complex gateway integrations. I have also worked on: • Semantic search systems using FAISS and embeddings • Knowledge graph-based architectures using Neo4j • Scalable backend APIs using FastAPI Core strengths: • Real-time AI systems (LLMs + streaming + APIs) • Backend engineering & system design • Machine learning, semantic search, and data pipelines I am actively looking for opportunities to build impactful AI systems, scalable backend architectures, and automation-driven products. Let’s connect and build something meaningful.
