01 / About
Engineer by craft. Builder by habit.
PhilippinesOpen to full-time and contract work
I'm Jayar Iglesias - a full stack engineer focused on web, mobile, and desktop software. I build clear interfaces, solid APIs, and realtime features when they matter.
I specialize in end-to-end product work: admin dashboards, cross-platform apps, logistics and SaaS tooling, and polished user experiences. Outside of work I'm outdoors a lot - trails, travel, and running.
02 / Capabilities
What I build
Practical strengths across platforms. Systems designed for clarity, performance, and real use.
Cross-Platform Apps
One product language across web, mobile, and desktop. Consistent UX without sacrificing platform feel.
AI-Augmented Products
Practical AI features that remove friction: smarter flows, less busywork, better decisions.
Immersive Interfaces
Motion, 3D, and realtime feedback used with intent. Presence over decoration.
