Software Engineer building and operating backend systems and applied-AI products end to end. I work across the full stack of a deployed product: Rust and Python services, PostgreSQL data modeling, React frontends, and the Docker and CI infrastructure that keeps them running. I am the founding engineer of Yupa, an accounting SaaS currently in technical pilot with micro-businesses, where I own architecture, delivery, security, and operations. I care most about correctness in financial code, measurable latency in AI pipelines, and systems that stay reliable without a team to babysit them.
