Experience

BitFantasma

A React-based app developed in Next.js framework using TypeScript. This small website connects to Firebase and Twitter API. There is a bot getting tweets upon tagging @bitfantasmabot and saving Tweet ID on Firebase. Then, we consult Twitter API on SSR using IDs stored in Firebase, where we can see how the transaction was valued when it was made and how the transaction will be valued now.

Fintech App for Business

Web and mobile app with a subscription model. I was leading a five-person team in the front end. We worked together with the back end to provide financial information to our customers about their cash flow distributed in different payment processor platforms.

Peronio.ar

A landing page for a customer launching an Argentinian cryptocurrency. This website has semi-complex animations, and it included an SEO-oriented development, where I used semantic tags and Next.js to fulfill this requirement and Framer Motion for animations.
