AI Engineer II at Vahan\.ai, Sep 2025 \- Jan 2026 · 5 mos, Bengaluru, Worked on the implementation of a chatbot agent utilizing Langchain & LangGraph with human\-like persona capable of delivery rider onboarding and user nudging\. Designed robust Prompt and Context Engineering frameworks to eliminate hallucinations in GPT\-4 based personas, ensuring high\-fidelity interactions\. Developed end\-to\-end ML pipeline from EDA, feature engineering to deployment, creating a CatBoost prediction model to forecast rider onboarding likelihood based on various journey touchpoints\. Developed a scalable voicebot using Pipecat, RabbitMQ, Redis and Milvus as vector database for job intent filtration of delivery workers

AI Research Engineer at Dubverse, Nov 2024 \- Oct 2025 · 1 yr, Gurugram, Haryana, India, Developed faster inference endpoints, reducing latency from 10s to 1\.2s while maintaining response quality\. Developed and fine\-tune Audio LLMs as part of a 5\-person team, increasing model accuracy by 25% for industry\-specific tasks\. Built custom data preprocessing pipelines that enhanced training efficiency by 40% and reduced model convergence time\. Spearheaded the development and deployment of a real\-time, multilingual Audio diffusion system, supporting 50\+ languages\.

Research Intern at Global DA Solutions Private Ltd, Dec 2021 \- Dec 2021 · 1 mo, Remote, Worked on End‑to‑end Spoken Conversational Question Answering system using Langchain and Pinecone vector database\. Utilizing various finetuning strategies \(LoRA, QLoRA\) for deploying LLMs on mobile devices

Senior Research Fellow, Speech & NLP lab at Department of Electrical Electronics and Communication Engineering, IIT Dharwad, Sep 2021 \- Oct 2024 · 3 yrs 2 mos, On\-site, Researched and built proof\-of\-concept AI models in Speech Recognition and Text classification\. Worked on developing Multimodal LLMs \(3B\+\) integrating vision, speech, and text capabilities resulting in a 40% improvement in cross\-domain task performance\. Worked on model optimization techniques like Onnx and TensorRT to improve inference performance during deployment\. Developed a novel distillation technique for multimodal\-LLMs reducing model complexity by 95% with no impact to performance\. Led a team of 4 engineers in developing a novel few\-shot framework for LLMs, enabling rapid adaptation to new domains with 70% less training data
