Work Experience

2021 — Now

Leading the design team to make MUI a one-stop shop for React UI libraries. I'm supporting various initiatives, from the core products ⎯ Material UI, Base UI, Joy UI, etc. ⎯ to growing the team & developing a more robust product culture.

2019 — 2021

Led the redesign of the driver app, which involved three major, operationally-wise, very complex rollouts that significantly impacted the whole company. Later on, went deeper into increasing the delivery success rate.

2019 — 2019

Led design for a breakthrough doctor-focused product, which gathered multiple distributed health data points to enable them to see their patients' holistic medical history for more precise and preventive action.

2018 — 2019

Designed the driver app from the ground up, supporting the first country-wide rollout until reaching a considerable maturity level, enabling the team to work on more specific problems such as driver earnings, delivery UX, onboarding, etc.

2017 — 2018

Joined as a design intern and contributed to all things design: from instructional branding animated videos to then landing on product design, helping optimize certain features of the driver app until iFood acquired the company.
