Hi, my name is Carlos. Nice to meet you.

I'm a self-taught software developer, currently volunteering for a non-profit while looking for my next full-time opportunity. I graduated with a Mechanical Engineering degree and am passionate about using technology to revolutionize traditional industries through automation and digitization. Previously, I was the CEO of an imports and exports company in Brazil where I restructured operations that led to multimillion dollar profits.

Besides technology, I've been to 65+ countries, all 7 continents and I love exploring new cultures and cuisines. Along the way, I discovered photography as a means to express my view of the world.

Projects
Wallet

Wallet is an automatic expense tracker app that syncs with bank accounts. The front end is programmed with React's Next.js framework, TailwindCSS for styles and Recharts library to generate all charts. The back end is running on a Node/Express server and auth is done with JSON web tokens. The app syncs with bank accounts using Plaid's API and webhooks to keep all accounts and transactions up to date.

CM Photography

I designed and wrote the code for my online photography store. I used React's Next.js framework and TailwindCSS to statically generate the front end. State is managed with React's Context API hooks and data with markdown files. Testing is done using Jest. I integrated the app with Prodigi's API for fulfillment of the prints and canvases, Stripe's API for payment processing and SendGrid API for email confirmations.

Our Global Trek

A personal travel blog that details my adventures around the globe. It was originally launched with a custom Wordpress theme that I later changed to React. The front end is rendered with Next.js and data is fetched from Wordpress as a Headless CMS using GraphQL.
