Walker Leite
Software Engineer at Fourier Labs
Florianopolis, Brazil

I have always been interested in functional programming, but found it difficult to effectively use in traditional projects built with JavaScript. To overcome this challenge, I immersed myself in the PureScript language for six months. This proved to be a much more ergonomic experience and also helped me learn Haskell. I then went on to complete the Plutus Pioneer Program with IOHK, a six-month program, and am now a tutor for new fellows at Lovelace Academy.

Yappi App
May 2020 - Aug 2021
The journey is basically the restaurant owner building menus and sharing it through Whatsapp, so customers can order without installing anything. To allow scalability to a realtime delivery service, and an offline-first experience, we chose to use RxDB in our PWA.

Parceiro da Construção - Saint Gobain
Mar 2019 - Aug 2020
We developed company apps (Calculadora, Guias, Rejuntes, Trilhas), a monolithic server for learning content management with authentication through passport. We also developed a micro-service to store user score and achievements through a immutable database (immudb). The idea with this micro-service was to have auditable time-series evolution of user progress through the learning platform.

Portal do Cliente - Orsegups
Jul 2019 - May 2020
We developed the customer panel of Orsegups, we developed the CI/CD infrastructure, and applied TDD and DDD concepts to server and client code. We created a dynamic generated docs from jsdoc with Vuepress for the dev team. The server is basically a gateway between many intranet company services. We have used caching and lazy loading techniques to improve perceived performance in the user experience.
