Experience
Reditus
https://getreditus.com/I started by migrating the front end from a Ruby on Rails monolith to a NextJS React application. I defined the architecture and conventions so that the contribution was consistent.
I designed the dashboard's branding and UX using Figma. This led to the creation of our own design system from scratch using Radix and HeadlessUI primitives.
Then, I contributed by brainstorming, designing, and building the next features of the product.
Tax Automation for Enterprise
https://www.fonoa.com/I was initially part of the Invoicing team, where I architected and built a dynamic Invoicing templating engine via Next.js. I also built an Invoice visual configurator within the Fonoa Dashboard.
Later, I was part of a critical time-constraint project that enabled third-party suppliers to manage their tax invoices. During this project, I led a team of two front-end engineers. The project was successfully delivered on time.
Finally, I was part of the front-end platform team, where I learned to create exceptional experiences for product teams. During this period, I contributed to the internal design system and led several initiatives, such as an RBAC system and Synthetic testing.
PropertyClub NYC
http://propertyclub.nyc/I've been working hand in hand with the CEO of the startup to come up with technical solutions and manage work with multiple collaborators (designers, SEO analysts, and other developers). I've been using the React framework on the front end and, occasionally, Ruby on Rails on the back end. I've also designed various layouts and UI elements and handled DevOps work by setting up the servers, initially on AWS and later migrating to Google Cloud.
The React app is a server-side rendered app via a custom Razzle boilerplate. Some of the libraries used on the website are Redux, Redux Form, React Loadable, Mapbox, and Sass.
