In this project, utilizing Ruby on Rails as the primary technology, I developed asubacquirer system, which is a payment intermediary used by retailers, acquirers, andcustomers. This system is particularly beneficial for small retailers as its integration doesnot require complexity, resulting in lower implementation costs and higher transactionrevenues. Additionally, I implemented microservices to facilitate communicationbetween the internal technologies of the system.

In the Nuuvem project, I worked on the development and maintenance of themarketplace using Ruby on Rails, with a focus on improving the frontend following bestpractices such as the BEM methodology. I also contributed to project optimization byimplementing a microservices architecture and developing a WASM-based gameplatform using TypeScript. Within the platform's architecture, I embraced functionalprogramming concepts, such as Flux, to create a state management system similar toRedux, without relying on frameworks like VueJS or React, in order to minimizeunnecessary code processing.Fun fact: During one of the prestigious MBA lectures at Harvard, CEO FernandoCampos presented a project that is sure to captivate gaming enthusiasts. The platformin question is capable of running AAA games in the browser, providing an experienceakin to native games. This is made possible thanks to the powerful WASM, a targetcompiler that generates binary code, enabling the execution of programming languagessuch as C, C++, and Rust in the browser with performance closely resembling that ofnative code. In addition to its remarkable nature, the platform will also allow players tostart the game immediately without the need to pre-download the entire content. This isachievable through streaming, which can be done in two ways: pixel streaming, similarto the approach used by Netflix, or asset streaming. In the latter case, once the browserdownloads the initial assets required for the first game phase, it initiates the game andsubsequently downloads the remaining assets in the background, without interferingwith gameplay.

In 2018, I participated in the development and maintenance of several projects. Amongthem, I highlight EasyLive, which was developed using the Ruby on Rails backendframework. I also worked on projects for the Fundação Roberto Marinho and CanalFutura, where Javascript/React.js was the primary technology used. Additionally, Icontributed to projects for Rock in Rio and OJK, which were developed with Ruby onRails on the backend and JavaScript on the frontend. My responsibilities encompassedboth development and maintenance tasks for these projects.

As a Game Developer, I was responsible for the development and modification of thegame "Aces High." I developed the entire Web Client using PHP and JavaScript, withintegrations using SocketIO. Additionally, I created the backend server using Node.jsand Express to establish communication between the WebClient and the MySQLDatabase. I implemented an advanced MatchMaking system for the game's MOBAmode and revamped the basic mechanics to enhance gameplay. Lastly, I alsocontributed to the partial development of a game mode utilizing Virtual Reality with Razer's OSVR.

As a Game Developer, my work entailed the development and modification of the game"Bushido Saga," documenting the entire project's source code and creating diagrams forbetter comprehension. I carried out a revamp and adjustments to the game'sarchitecture, enabling scalable development. Additionally, I revamped the gamemechanics, including the hero's AI, NPCs, and enemies. Furthermore, I partiallydeveloped a new gameplay style in the form of an Action Mode.

As a Game Developer, I was responsible for the development and modifications of thegame "Life Defenders," as well as the creation and updating of mini-games within themain game. I utilized ActionScript 3 and PHP programming languages to implementthese features. Additionally, I took charge of developing a barcode scanning system formarkets, aiming to enhance the user experience during their shopping endeavors.

As a Game Developer, I was responsible for the development of the game "The Light ofthe Darkness" in ActionScript 3. My main responsibilities included programming thelevel design, creating enemy artificial intelligence, and implementing screencomponents. Additionally, I developed an attribute modification system in Adobe AIR,enabling players to customize their gaming experiences in a more dynamic andinteractive way. My contribution to this project significantly enhanced the game's qualityand success, making it one of my most visually stunning portfolios.
