Daniel — Full Stack Engineer

FULL STACK ENGINEER

Currently atKappabuilding Zigzag · Caracas, remote

Full stack, frontend by specialty: I ship the whole product and care most about the layer people actually touch.

My strong suits are iOS development and product design, from the first flow sketch to the shipped app.

Work Experience

Where I've shipped: security tooling, collaboration apps and storefronts — from the UI down to the backend.
