What I'm looking for

I am seeking a full-time AI Engineer role where I can build production-grade LLM systems, work cross-functionally, and grow in a collaborative, product-focused team.

I am an AI Engineer with hands-on experience building and deploying LLM-powered applications, including production-grade RAG systems, agentic workflows, and domain-specific fine-tuning. I have delivered solutions across recruitment automation, control testing, and healthcare, optimizing inference pipelines for latency and cost.

I collaborate closely with product and backend teams to deploy GenAI features on cloud platforms like AWS and Hugging Face Spaces, and I mentor peers on prompt engineering, RAG, and agent design. My projects include multimodal retrieval pipelines and Streamlit-based user interfaces that significantly improved efficiency and user outcomes.
