Led the end-to-end product development of Atiend Calls, from AI infrastructure and telephony integrations to UX/UI and design system.
I'm Matias Monzalvo
22yo design engineer based in Buenos Aires. I turn complex problems into clear, useful digital products, moving from early strategy to shipped details and building the systems that keep every experience coherent as it grows.
This is the tool I work with every day.

Skills & Experience
These are the tools, languages, and systems I use in my day-to-day work, along with the experiences that have shaped how I approach it.
AI-first
I use AI as part of my day-to-day work.
I move between several tools depending on the task, give them context and constraints, and review what they produce before using it.
Education
I'm in the final year of my university degree.
I have also learned through a Cambridge C1, hackathons, courses, side projects, sales, and years of customer support. Each experience has given me a different way to approach the work.

UX / UI
I like making interfaces clear and consistent.
I use simple systems for spacing, type, and states, and I try to make every screen easy to understand and use on any screen or device.
Stack
I use different tools for different kinds of work.
My day-to-day moves from design and front-end code to databases, deployment, and AI tools, depending on what the task needs.
