About

KaijuBytes — AI Specialist & Full-Stack Systems Engineer

KaijuBytes is the engineering practice of an AI Software Engineer based in the Philippines — someone who ships AI features end to end, from architecture through implementation to production. Currently at the Department of Social Welfare and Development (DSWD), designing and deploying intelligent document processing systems for government operations.

My main project, the IDP System, is a production enterprise platform with multi-provider AI extraction, RAG-based document Q&A, human-in-the-loop review workflows, and multi-tenant RBAC. I built it as a solo developer using AI-augmented development — architecting the system myself and orchestrating AI-assisted implementation to achieve the velocity of a small team.

Outside government work, I build under the KaijuBytes brand: Aninaya, a local-first Android personal-finance app published on Google Play with on-device AI receipt extraction; and Atlas, a voice + text multi-agent assistant with an offline-first architecture. The same architecture-first, empirically-validated approach runs through all of it.

Before DSWD, I was a Computer Programmer at the Department of Information and Communications Technology (DICT), where I deployed disaster risk reduction systems, built automation tools, and prototyped AI chatbots. I also spent time as a researcher at UP Los Baños, where I built the wireless sensor network system that became Lo-CADIS Sprout.
