Looking forward to connect with clients, or dev teams.
Hi, everyone Glad to see you here again. As I already mentioned before, I build and run AI systems in production. Most of my work is around LLM apps, generative pipelines, and agent workflows, along with the backend pieces that keep them stable โ€” retrieval, data pipelines, and evaluation. I mainly work in Python with PyTorch and Hugging Face. I build APIs with FastAPI or gRPC, and deploy using Docker, Kubernetes, and GPU stacks like vLLM and Triton. I also use tools like LangChain or LlamaIndex. Iโ€™m used to owning things end-to-end, from design through to production. If youโ€™re working on something real in this space, happy to connect.

Hello.
I am currently working in the field of AI and Full Stack. My long-term contract with Exa company in the U.S. expired 3 months ago, and I am currently seeking new remote work opportunities. With 7 years of experience as an engineer, expanding my reach beyond Japan to the global market is very important to me. I already have experience working remotely and have a proven track record of collaborating effectively with companies, so I look forward to connecting with individuals and companies interested in product launches or system improvements. Thank you.
