What I'm looking for

I seek roles building production LLM/RAG systems with strong MLOps, collaborative teams, cloud-first infrastructure, mentorship opportunities and measurable business impact.

I am an ML Engineer with 7+ years of IT experience focused on machine learning, AI, and production MLOps. I specialize in LLMs, Retrieval-Augmented Generation, OCR, NLP, and deploying scalable AI systems on cloud platforms.

In my current role I built RAG+LLM chatbots and agentic AI solutions, cutting costs by 45% for a credit-card BPO and reducing invoice/receipt processing costs by 90% by moving from OCR to LLM-based approaches.

I have hands-on experience with model evaluation and orchestration across GPT-4, Claude, GeminiAI and LLaMA, and I employ tools like LangChain, LangFlow, MLflow, Weights & Biases, and vector databases (Milvus, Pinecone, Weaviate) for robust pipelines and A/B testing.

I bring full-stack experience in Python and Flask, cloud deployment expertise on GCP and Azure, plus bilingual Japanese capability (JLPT N2 / BJT-J3), enabling cross-functional collaboration and mentorship in AI/ML projects.
