  • Machine Translation System with Falcon, Bloom, and GPT-3.5: Developed a robust machine translation system utilizing Falcon, Bloom, and GPT-3.5 to achieve high accuracy and context-awareness across multiple languages. The efforts involved fine-tuning of open source LLMs for language specific translation tasks. This solution enabled seamless communication and information exchange by preserving the nuances of language, even in complex or technical texts.• Custom Q&A System Using RAG with LangChain and Haystack: Built a Retrieval-Augmented Generation (RAG) system leveraging LangChain, Chroma, and Haystack. This solution enables dynamic interactions with a custom Q&A database, allowing users to ask specific questions and receive accurate, context-driven responses, making it ideal for customer support or knowledge management.• Enhanced Data Retrieval with Mistral and GPT-3.5: Integrated models like Mistral and GPT-3.5 into a data retrieval pipeline, optimizing response accuracy and relevance. By using these models, I developed a system that can handle complex queries and retrieve information from large datasets efficiently, aiding in research, data analysis, and decision-making processes.
