From the first line of backend code using technologies like Node, NestJS or Hapi, to infrastructure management with tools such as Terraform and Ansible. Expert in taking over legacy systems, identifying and mapping improvements to enhance scalability, maintainability and security.

I work towards enabling our members to enhance their quality of life and access to healthcare through technology. My focus is on solving complex problems with simpler, scalable, and more efficient solutions.To achieve this, we utilize an event-driven microservices architecture in the AWS cloud. This involves configuring API gateways, writing lambda code, and integrating with queue and messaging services. Consequently, I am responsible for designing and implementing backend services and APIs using TypeScript, Node.js, and NestJS.Additionally, as the Mobile Lead, my responsibilities include recruiting and selecting team members, analyzing requirements, defining architecture, and overseeing the development process from the initial lines of code to the publication of Android and iOS apps using Flutter.

During my work on the Claro Pay project, I delivered a digital wallet application developed in Flutter to Claro S/A. As part of this project, I integrated the application with the Quarkus backend and Open API. Throughout the development process, I worked closely with the team to scale the app from 5000 users to nearly 1 million users.

As the first developer of the project, I worked alongside one other developer, one product manager, and one designer from the initial idea to the launch of the Flutter app on both Android and iOS app stores. Our team was highly competent and dedicated to bringing the project to fruition. During my time on the project, I played a vital role in the architecture design and was responsible for integrating the app with services that could check a car's license plate to identify its make, model, and year. Furthermore, I integrated the app with the New Zealand car market to display the car prices to the user.

During the beginning of the COVID-19 pandemic, I contributed as a cross-platform developer for mobile and web applications, playing a vital role in the digital transformation and innovation process of the hospital. Working during such a crucial time allowed us to develop health solutions in record time. I integrated Dart/Flutter applications with native code and backends, ensuring seamless performance across platforms. Additionally, I developed libraries and implemented responsive solutions for the Flutter web solution.

I contributed to the development of the Flutter application for BMW/MINI, which required integration with car systems. I also played an essential role in developing and maintaining Backends for Frontend, utilizing a variety of languages, including C#, Java, and JavaScript/TypeScript with NodeJS, as well as (Effective) Dart/Flutter (with BLoC). During this project, I followed test-driven development practices (with SonarQube) and utilized data/events (with Elastic Search, Grafana, and Kibana) to ensure efficient and effective project delivery. Through this experience, I gained familiarity with various design patterns and pipelines in a cloud architecture and large DevOps culture (GitHub, AppCenter, Docker, Kubernetes, Jenkins, and Terraform). As part of an international project with teams located around the world, I worked in English.
