Bruno Simplicio

I was one of the initial engineers when the company consisted only of the founders and myself. Collaborating closely with the CTO, I contributed significantly to the development of a travel rule API and dashboard, enabling crypto companies to adhere to country regulations. My involvement extended to key projects, including crafting a decision rules engine for transactions, developing a widget for exchanges to collect data, and more recently, assisting in the transition from a monorepo to more agile microservices. In this transformation, we utilized Kafka to ensure better communication, elevate overall system availability, and enhance scalability. In the dynamic setting of a startup's early stages, my role expanded beyond technical contributions. I actively participated in hiring, interviewing, and onboarding new engineers—reflecting the versatility required in wearing multiple hats to support the company's growth.

With a compact team of developers and one project manager, we successfully scoped and built an application to automate the API design process for the Open Finance initiative at Banco do Brasil. Developed using Node.js and PostgreSQL, this application was specifically designed to streamline the bank's workflow by minimizing the time dedicated to manual API design.

For a duration of two years, I took on the role of leading a team of developers in the creation of the Open Finance developer platform for the bank. This platform was strategically developed to facilitate the sale of API services by the bank and to enhance the overall experience for external developers. The platform itself was built using a combination of Angular and Java.

I played a key role in the transformation of legacy banking services into modern RESTful APIs, actively contributing to the development of API functionalities using Java. The security of these APIs was strengthened through the implementation of OAuth 2.0 protocols for enhanced protection.

Throughout this period, I actively collaborated with a team of experienced developers on several key projects utilizing AngularJS and Java. This phase was particularly important for me, providing valuable experiences and insights
