Nirbhay Tiwari — CTO
Hi, I’m nirbhay tiwari — a Generative AI Engineer focused on building real-world, production-grade AI systems. I work at the intersection of LLMs, RAG architectures, and intelligent system design, where the goal is not just to build AI models, but to make them reliable, scalable, and usable in real-world scenarios. Currently at Birlasoft, I’m working on a RAG-based medical AI application built on large-scale proprietary and confidential datasets. My work involves designing end-to-end retrieval pipelines, improving context understanding, building agentic architecture, writing effective system prompts across application and ensuring the system delivers accurate and explainable responses in a highly sensitive domain. Before this, at Turing, I contributed to Google’s Gemini project, where I worked on large-scale LLM improvement workflows. I was part of a team delivering 2,500+ high-quality Colab notebooks focused on enhancing model understanding, improving response quality, and reducing error rates. I also designed 500+ real-world and synthetic API scenarios for LLM training, and worked on structured prompt testing that improved model responsiveness and consistency. In addition, I’ve developed and deployed AI/ML solutions for EV startups, supply chain startups, where I worked on tasks like text classification and intelligent data extraction, achieving high accuracy and delivering measurable business impact. What I Do I Build end-to-end RAG systems (chunking strategies, embeddings, retrieval optimization, bot response evaluation pipeline) Design agentic workflows for complex problem-solving Work on LLM evaluation, prompt engineering, and model reliability Handle challenges like hallucination reduction, domain adaptation, and response accuracy Tech Stack Python | FastAPI | SQL Generative AI | RAG | Agentic AI | NLP LLM Fine-tuning | RLHF | SFT | Prompt Engineering Data Analysis | Visualization Beyond Work I also enjoy leading a team of ai enthusiasts and have led a team of data scientists. I’m always curious about pushing AI systems beyond prototypes — into robust, production-ready solutions that actually solve problems at scale.
