This native iOS app was made to help me to analyze and manage my stock portfolio. The development uses SwiftUI for the app, node.js, Redis and MongoDB for the backend.Using it I can import my brokerage's PDF or insert it manually. Doing that the system calculates the average price for which stock considering the paid taxes.Also, it automatically recognizes when there are sales and if I had profits or losses with it. This way, it can manage the losses to compensate and in case I have taxes to pay over the profit, the app generates for me a record with all the information I need to pay this tax.In this app, we can manage multiple wallets and we can see a summary with live information for each. This live information gives us every stock price in real-time, this way we know the amount we started the day, the amount we invested, and how much we have right now but also the result for each stock since we bought it and the daily result.The app also shows on the Home Screen some general information that I believe is helpful such as the price of the dollar (in Brazilian Reals), inflation, etc... this information is numbers I use to check but I had to find each in a different place before this app.The app also has a screen where I can check if a stock is now with a good price to buy considering the logic/calculation created by Luiz Barsi (probably the biggest Brazilian investor).Not less important, the app also shows us a pie chart for the consolidated wallet split by categories we create and set for each stock, as selecting a category, it shows a pie chart for that category so we can know what is the percentage of that stock in that category.

Full-Stack developer since 2018 working with KinBox Ltd in London UK on family app projects and educational history apps.Initially, I worked as a mobile developer using Xamarin to create apps for Android and iOS. After a few months, we started a new project called gcsehistory.com with an app called CleaverLili where I worked as a Full-Stack developer.Gcsehistory.com is a place where students can learn more about history to get ready for their GCSE exams. As a full-stack developer, I participated in the implementation of our back-end where we have our logic in Node.js using MongoDB and Redis for our data persistence. Also, we implemented a service in Python providing artificial intelligence for a chat feature we had (I'll explain more). For Android and IOS, we used native languages (Kotlin and Swift). Finally, for our web app, we used VueJS.As features, we have a quiz game, we have school class management, homework applied by teachers, tests applied by teachers, a flow to guide the student through the content to learn and a chat. On every feature, where the user has text to read, he also has a karaoke option that's a voice reading the text as it becomes highlighted, helping the student to focus and follow the content.In the chat feature, the user can also send messages by text or audio, and our A.I. process the message and answer the user with the most accurate content. So, the user could initiate a conversation with our bot, then ask something about history as "What were the reasons for world war 2" and right away he gets an answer explaining all the reasons for it. Continuing, we could say for example: "how won it?" or also change the subject/context to something like "Who was Roosevelt?". That chat is something really cool to revise some study topics.
