01 / About
Engineering at the intersection of software, AI, and infrastructure.
I am a software and AI engineer with a telecommunications foundation. I pair systems thinking with practical product development - from Spring Boot banking APIs and cloud services to retrieval-augmented AI applications.
My work spans fintech, healthcare, document intelligence, and network infrastructure. I care about clear systems, useful interfaces, and software that holds up in the real world.
