Paystand

Senior FullStack Developer

Nov 2022 - Jul 2023

I worked as a fullstack developer on a credit card system. Users use their credit card anywhere visa was accepted, in the single page app users can activate their cards, increase/reduce their valance, see their transactions or download them in csv files.

The FrontEnd is a Create React App and for the state management we used Context Reducer and some customized Hooks. The BackEnd is a Koa.js rest api. As Solidfi is the actual system that performs the payments we have to listen to the event Solidfi sends us so we implement kafka to react everytime the user perform a payment with their cards.

I Designed and Developed the Front-End Architecture from scratch of “Integrations”. Single page app built on React with Typescript. Always following best practices and implementing the Presentational and Container Component Pattern. As we applied separation of concerns, we end up having quite a few “extra” components to keep in track what component was in charge of what we made used of a tool call TypeDoc to build a wiki for the code. The main purpose of integrations is as the name says. We integrated our CRM with many third-party vendors, such as google maps, quickbooks, outlook and many more. Redux is implemented as the state manager. To ensure the scalability of the system we implemented the Redux Ducks Pattern. By nature of the app to be able to connect with different type of sources we implemented redux-saga to handle high level of concurrency we applied the Generator – Promise Pattern. Integrations is built with a mobile rst approach and using the 7 in 1 architecture styling pattern of SASS/SCSS.
