I am one of the people responsible for developing the company's main product: the BEE4 Traders platform and its external integration API. My work focuses on creating innovative and scalable solutions, contributing to the evolution of the Brazilian access market, unlocking opportunities, enabling new businesses and boosting the growth of the national economy. As one of the technical leaders, I generate value for both listed companies and investors, offering solutions that facilitate access to new sources of funding for business expansion. In addition, we promote visibility in the capital markets and create diversification opportunities, allowing investors to trade shares in emerging and innovative companies that are shaping the future. In my day-to-day work, I use an ecosystem of cutting-edge technologies, including Node.js, TypeScript, NestJS, .NET, Java, Kubernetes, Solidity, AWS, NoSQL Databases, Redis Cloud, Relational Databases, Kafka, SQS, WebSocket, gRPC, FIX Protocol and Hyperledger Besu.

I participated in the development of BitID, a customer onboarding platform for financial institutions, using blockchain to guarantee security, performance and reliability in the handling of sensitive data. The solution gives customers total control over their data, allowing them to enable or revoke access to institutions at any time. As a software engineer, I contributed to the optimization of onboarding processes, ensuring efficiency and security in data validation. In addition, we created a customer-centric experience, providing visibility and control over the use of their data, with the possibility of managing access and consulting the purpose of each use. The technology stack involved Node.js, TypeScript, Express, Solidity, GCP, relational databases and the Hyperledger Besu network. I also developed smart contracts and used tools such as OpenZeppelin, HardHat and Truffle to guarantee the security and functionality of the solution.
