Building AI Systems with RAG & LLMs | AI Engineer | Python • LangChain • Chroma • Ollama | Ex-Software Developer Intern @ Eleics Design

About

I build AI systems that go beyond basic prompting by integrating Large Language Models with real-world data. During my internship as a Software Developer at Eleics Design, I worked on developing Retrieval-Augmented Generation (RAG) based applications and LLM-powered solutions. I built an end-to-end offline document-based Question Answering system, focusing on data privacy and efficient information retrieval. My work included: ● Designing complete RAG pipelines (ingestion → embedding → retrieval → generation) ● Implementing semantic search using vector databases (Chroma) ● Integrating local LLMs (Ollama / llama.cpp) for offline AI processing ● Optimizing chunking strategies and retrieval accuracy for better response quality In addition, I have experience in full-stack development, where I built multiple web applications using HTML, CSS, JavaScript, PHP, and MySQL. Tech Stack: Python, LangChain, Chroma, Ollama, JavaScript, PHP, MySQL I am actively seeking full-time opportunities in Generative AI, LLM Applications, and AI Engineering where I can contribute to building scalable, data-driven AI systems. Let’s connect if you’re working on something impactful in AI.
