Jaylord Vhan Fabor (Jjay Fabor)

Software Engineer — @JjayFabor — based in Iloilo City, Philippines.

I build clean, reliable, and scalable backend systems — from APIs and database design to automation — with well-structured code that's easy to maintain and built to last.

I focus on productive, real-world applications: clean, scalable backends and APIs, and automated workflows that save teams hours of manual work. Lately I've been leveraging AI to make products genuinely more useful — integrating AI voice agents, automating business processes with n8n, and wiring LLMs into real workflows.
