What I'm looking for

I'm looking to build and evaluate practical AI applications, particularly LLM, RAG, and NLP systems, while continuing to deepen my experience in model evaluation, fine-tuning, testing, and deployment.

I'm an AI Engineer with a strong foundation in backend development, specializing in building and deploying production-grade RAG applications and fine-tuned LLMs. From evaluating frontier models to architecting scalable REST APIs with Python and FastAPI, I focus on turning complex technical requirements into reliable, real-world systems. I thrive on solving high-impact problems, keeping architecture clean, and making sure AI solutions actually work in production.
