Oscar Chinbat

I design and build AI-powered products, end to end.

I'm a software developer who builds end-to-end solutions across web, mobile, and AI/ML. I focus on applying machine learning and retrieval-augmented generation (RAG) to solve real-world problems, with a strong interest in developing secure, reliable, and scalable software.

02About

I’m a software engineer working where machine learning meets product. Most of what I build starts as a hard retrieval or reasoning problem and ends as something people can actually use — a legal research assistant, a trading companion, a classroom platform.

My work spans RAG pipelines and agent workflows, full-stack web and mobile development, and the infrastructure that keeps them running. I care about the unglamorous parts: evaluation, latency, correctness, and interfaces that stay legible under real data.

I’m finishing a B.S. in Computer Science at Central Washington University, where I’ve also worked as an AI/ML researcher and taught data structures as a TA.
