About
🚀 Team Lead – Data Science | Builder | GenAI Enthusiast I’m a builder at heart — passionate about taking ideas from whiteboard to real-world impact. Whether it’s shipping production-ready GenAI systems or experimenting with the latest in LLMs, I thrive in environments where I can move fast, build from scratch, and lead teams solving meaningful problems. 👨💻 Current Role At Roboxa Technologies Pvt. Ltd., I lead the Generative AI efforts as a Team Lead – Data Science Engineer. My day-to-day involves working with: LLMs (open-source & API-based) LangChain, RAG pipelines, and Vector Stores LoRA fine-tuning using Hugging Face Building GenAI-powered tools and internal systems Architecting end-to-end pipelines, from data to deployment 🧠 Research Background Previously, I completed a research internship at IIT Jodhpur under the SoNAA (Social Network Analysis) Group, where I worked on Graph Neural Networks (GNNs) and deep learning models for analyzing complex social structures. This academic grounding gave me a strong foundation in applied ML and scalable model development. 🛠️ Tech Stack Languages: Python, C++ Frameworks: PyTorch, TensorFlow, LangChain Tools: Hugging Face, Streamlit, Docker, Git Infra: AWS, Colab Pro, REST APIs, Vector DBs (FAISS, Pinecone) 🌱 What Drives Me I don’t have many hobbies outside of coding — I don’t sing, dance, or drink. What I do love is building. I’m most alive when I’m solving real-world problems with code, especially in small, focused teams where ownership is high and the mission is clear. 📌 Always open to collaboration in: Early-stage product/infra roles GenAI/LLM startups Open-source AI initiatives AI R&D projects Let’s connect if you’re building something meaningful!
