About

AI Developer at Samsung with 2 and half years of experience spanning software development, system performance optimization, and now cutting-edge work in AI and LLMs. 🌟 Currently building AI Agents from scratch to automate Data Analyst workflows — from natural language interaction to SQL generation and real-time data retrieval using Samsung’s DCS data portal. 🔍 Previously optimized a large-scale C++ testing framework, improving execution time by 40% using parallel execution and memory fixes. Awarded the Samsung Spot Award for outstanding contribution. 🚀 Tech I'm hands-on with: Python, LLMs, RAG (Retrieval-Augmented Generation), Streamlit, VectorDBs, SQL, and C++ (legacy projects). I’m now exploring AI-focused or software developer roles where I can scale these learnings and contribute to high-impact products. Let’s connect!

Machine Learning Engineer

Aug 2023 – Present · 2 yrs 8 mos · Bengaluru, Karnataka, India · On-site

Designed and optimized a Large Language Model–driven Natural Language to SQL (NL-to-SQL) system for complex query understanding and structured data retrieval.
Performed LoRA-based parameter-efficient fine-tuning on proprietary NL–SQL pairs, directly modifying model weights to improve semantic-to-syntax mapping accuracy.
Further enhanced model robustness through a Reinforcement Learning from Human Feedback (GPRO) loop that leveraged user corrections for continuous retraining — demonstrating deep understanding of LLM fine-tuning, adaptation, and performance optimization.
Engineered an NL-to-SQL pipeline with query decomposition, translating complex natural language queries into sub-queries and merging their outputs into final executable SQL commands.
Integrated the pipeline into a Full-Stack AI Assistant built using Python, LangChain, Llama, RAG, Vector Databases, and SQL, reducing analysis time by 40% and achieving 97% mapping accuracy on sub-query translation.
