• Built custom Retrieval-Augmented Generation (RAG) pipelines combining vector databases (Faiss, Pinecone), Langchain orchestration, and LLMs (LLaMA, GPT, Falcon) for knowledge-intensive tasks (e.g. support automation, document Q&A, expert systems).
• Fine-tuned open-source models (LLaMA, Mistral) on domain-specific corpora using PEFT (LoRA) and supervised fine-tuning.
• Integrated embedding generation workflows (OpenAI, HuggingFace) for scalable vectorization and semantic search.
• Deployed inference services with FastAPI, Docker, and GPU orchestration on AWS/GCP.
• Ensured latency/quality tradeoffs with prompt engineering, reranking, and hybrid retrieval.
• Contributed to architectural decisions: RAG vs Finetuning, latency vs accuracy, model hosting strategies.
• Collaborated with cross-functional teams (product, infra, business) to translate abstract ideas into working prototypes.
