In this company I worked with a platform for issuing promotional walletpasses for third-party companies. In this project I was responsible for:Create and test unique token creation functions on the Hedera block chain.Create and test graphical components for the internal library of the React-based platform.My contributions:-To create the graphic library and the platform interface, React was used together with Typescript, and Tailwind was used for styling.- For the back-end, it is worth highlighting that the entire infrastructure was structured within the AWS cloud,using the following services: .For the api system, an architecture was used almost entirely based on triggering a lambda function togetherwith the api gateway. It is worth noting that these functions were written in Typescript .For the asynchronous communication system between the lambdas, the SQS and SNS messaging service wasused. To create a wallet pass, the issued tokens use the Hedera block chain network.

I’ve supervised and created containerized solutions with docker based on microservices architecture, deployed on GCP (Google Cloud Platform). Among the systems I’ve developed are: Students platform where the students can see their development through the course, make algorithm exercises corrected in real time, access daily activities and deliver projects.Platform for the staff to create exercises, classes, monitor students performance and manage teams.An extension on VS Code for tracking students coding time.My contributions:-I’ve developed modern and intuitive interfaces for the described systems above. I’ve used technologies such as Typescript, React, HTML and CSS. I also followed the Microfrontends Architecture in some services.- For the back-end I’ve created containerized applications with Docker. The entire infrastructure was based on the microservices architecture and each service had its own particularities. About the used technologies: .For database: postgres, mongoDB. .For the application: Typescript and jest using the TDD technique(Test-driven development) for the tests. .For the infrastructure: Several GCP’s (Google Cloud Platform) services were used, the most relevants being google Cloud run, Virtual Machines, SQL, Cloud Storage and Pub/Sub (Publish–subscribe pattern for communication between containers).-I’ve supervised the entire continuous delivery process done through github actions. In addition, I’ve also reviewed pull requests from my team.

My master's research is about computational branch, focusing on the creation of civil engineering software for automated calculations of structures (buildings). My contributions:-I created a new data structure for the LESM software (LINEAR ELEMENTS STRUCTURE MODEL), made in Matlab and object oriented.-I added the functionality of dimensioning of metallic profile following the precepts of NBR8800. For that, I analyzed the existing code and added classes responsible for performing the calculations and returning a report detailing them.-Along with Matlab I added JavaScript, Css and Html in order to obtain better visual feedback on the details of the calculation performed by the program.

I learned Javascript, GraphQL and new Rest Api architectures to contribute to projects that were already under development. To better interact with the team, I also learned Spanish. My contributions:-Elaboration of development standards for the front-end (boilerplate), where React, Styled Components, Jest (unit tests) were used. -Regarding the connection to the backend, I created efficient organizational structures based on Medium articles. In some projects, I used Graphql queries and in others Rest applications.-I created reusable and responsive React components for different types of screens, which were used by the project team.-For the back-end, I created new tables and relationships using TypeORM and new Routes according to the inclusion of new features such as: kanbans, external Apis request and information storage, user information management, among others.-I assisted in the creation of authentication routes using JWT.-I reviewed and performed the quality control of the project weekly using the Gitlab tool.

Taught tutoring for undergraduates.I taught classes of:prestressed concretehyperstatic structures

Analyzing the need of the university I developed an application to help studentsMain contribution:System designed to notify students about college events.
