Hello, I'm
Julius Nowel B. Santiago
Technical Lead & Full-Stack Developer
Building AI-powered products — LLM APIs, agents & automation
I lead and build production-grade, multi-tenant SaaS end-to-end (Laravel + Next.js) — appointment-booking and inventory platforms — and I build AI into products: an LLM-powered customer-engagement layer that drafts and automates replies with the right guardrails and human handoff.
