I’m an AI Engineer with 4.5+ years of experience in LLM training, RLHF, prompt engineering, and RAG pipelines. I’m currently training production LLMs for US clients at Outlier AI, where I focus on improving accuracy and chatbot reliability.

In my work, I design and evaluate prompts for code generation, reasoning, and chatbot tasks, and I build RAG pipelines with LangChain + Azure OpenAI for enterprise use cases. I’ve trained and evaluated models using RLHF techniques, improving model accuracy by 30%, and I’ve reduced hallucinations by 40% through RAG implementations, while maintaining a 4.8/5 quality rating with 100% on-time delivery in EST timezone collaboration.

Before AI-focused work, I developed .NET Core web applications with SQL Server for 10k+ users and led migrations to Azure Cloud, reducing costs by 25%. I also build evaluation and feedback systems—like an LLM code quality framework across 15 programming languages—and I fine-tune GPT-4 and Llama models for domain-specific applications.
