At Halo, I played a key role in developing and optimizing enterprise-grade platforms, including the VIP project for Mercer and another large-scale cloud-based application. My focus was on full-stack development, cloud infrastructure, and DevOps, ensuring performance, scalability, and security. Key Contributions: • Developed applications with NestJS, Angular, and MongoDB, ensuring high performance and modularity. • Implemented a custom queue engine using MongoDB, enhancing asynchronous processing and system efficiency. • Designed a cloud-native architecture on AWS, leveraging: • Serverless Lambdas (Python & TypeScript) for automation and event-driven workflows. • DynamoDB & MySQL (RDS) for scalable data storage solutions. • AWS services like SQS, SES, and EventBridge to improve messaging, automation, and observability. • Developed a secure authentication middleware, separating business logic from identity management. • Optimized MongoDB queries for high-volume datasets, significantly improving system responsiveness. • Designed and implemented a data export pipeline to AWS S3, automating report generation and storage. • Implemented an Nx monorepo, allowing modular development and efficient code sharing between services. • Developed custom Nx tasks to streamline CI/CD processes, optimize build times, and enforce coding standards. • Created a shared library within Nx to standardize authentication, logging, and utility functions across multiple services. • Led the CI/CD strategy using GitHub Actions and SonarQube to enforce code quality. • Improved system observability by integrating AWS X-Ray, Sentry, and CloudWatch for monitoring and debugging. This role allowed me to lead development teams, architect scalable solutions, and refine DevOps strategies, while also ensuring high system availability and maintainability. • As part of my role, I define and develop applications based on client requirements. • I currently work on a health project for Mercer, leveraging Docker containers and Kubernetes for deployment. • The tech stack includes Nest JS and Angular, with MongoDB as the database. • I have implemented key processes such as a Mongo queue manager and integrations with AWS SES, among other solutions. • Additionally, I provide support and mentorship to junior developers, fostering their growth and ensuring the team's technical excellence.

I worked on an exciting project called TYB, which involves blockchain and NFTs. Our application is being developed using ReactJS for the frontend and NestJS for the backend, and we are leveraging AWS cloud services to manage queues and other aspects of the project. • Sadly, my project was cancelled and team was affected by Lay-offs. Skills: GraphQL • NestJS • Linux • Bases de datos • Desarrollo de software • Git

My primary focus is on analyzing, developing, and maintaining a payment processing application. This involves validating existing features to ensure proper functionality and creating new features to enhance the product. As a team leader, I manage a team of five individuals and oversee the implementation of new features. During my time in this role, we successfully transformed a group of individuals into a cohesive team and developed a new version of the payment application called Migo, which is specifically designed for C-Commerce and is used globally. • My primary focus was to analyze, develop, and maintain a payment processing application. Skills: Node.js • NX • Linux • Databases • Desarrollo de software • Git

• We work to facilitate international transactions and support charities around the world. • Part of the team's job is to manage international campaigns and use all the technology available, including external and internal to the company. • All this is based on the PayPal features using automated tests, frontend with ReactJS and more.

Developing awesome solutions for learning and attention measurement with Brain.Co Technology. • I led a team that created multiple minimum viable products (MVPs) for Novuskills, covering various scopes including mobile, desktop, and web applications. • Two of these products were created in partnership with BrainCo and Dale Carnegie and incorporated neuroscience techniques to understand user attention levels and behavior. • Our team built the mobile application using Flutter and developed several libraries for internal use. • Additionally, we designed and implemented a comprehensive cloud infrastructure based on Google Cloud Platform (GCP), utilizing both SQL and NoSQL databases. • The web frontend was developed using Angular and was built to high-quality specifications.

• I developed MVPs for mobile, desktop, and web applications, working on: • Flutter-based mobile applications, ensuring cross-platform compatibility. • Google Cloud Platform (GCP) integrations, leveraging both SQL and NoSQL databases. • Collaborations with BrainCo and Dale Carnegie to create neuroscience-based applications. • This role deepened my expertise in early-stage product development, cloud integrations, and cross-platform mobile development.

• As a Backend Developer, I specialize in using a variety of technologies, including Python, NodeJS, and Java. • In this role, I had the opportunity to work on an exciting project that involved developing a solution for a massive SMS sender in collaboration with companies like Tigo. • Working alongside a cross-functional team, I was responsible for designing, developing, and implementing the backend infrastructure that powered the SMS sender. • This involved building a highly scalable and efficient system that could handle large volumes of SMS messages in real-time.

• As an Android Senior Software Developer, I specialized in developing robust applications using dependency injection (Dagger2), MVP architecture, and RESTful APIs. • I have extensive experience of creating high-quality apps and connecting them with multiple APIs. • One of my notable achievements includes creating an event registration app called TodoTicket. • Using real-time access and Firebase, we designed and developed a seamless and user-friendly app that enabled users to register and attend events with ease. • The app was built using the latest technologies and frameworks, including dependency injection (using Dagger2) and MVP architecture, to ensure the highest quality and efficiency.

• I worked closely with the Senior Developer to develop innovative solutions for a remittances-focused company. • Together, we designed and implemented custom software solutions to help streamline and optimize the company's remittance processes. • Our work involved developing various software applications, including mobile and web applications, APIs, and integration with third-party systems. • We also collaborated with cross-functional teams to ensure that our solutions aligned with the company's overall goals and objectives. • Throughout the development process, I utilized various technologies and tools to ensure that our solutions were efficient, scalable, and user-friendly. • Additionally, I worked closely with the Senior Developer to incorporate best practices and ensure that our solutions were well-architected and maintainable.
