Java + Angular Development

Bank of Brazil (BB)

As an experienced Java developer, I easily integrated the team, bringing with me best practices of software development, such as: pull requests, code reviews, TDD, while also learning about the processes and achitechtural designs the company already has in place to facilitate inter-teams cooperation.

• Created many microsservices (Java + Quarkus), and REST APIs, and integrated them with the frontend (in Angular)
• Kept our projects updated, with current dependencies, using the best coding practices and high code coverage
• Have been recognized twice (2023, 2024) as a "culture highlight" (the top 10% employees that foster a collaborative team culture) for my contribuitions for the company

Kotlin + React Development

Brazilian Federal Court of Accounts (TCU)

As a senior developer for key projects that tracked government spending, I helped develop new modules to track signs of misuse of funds, with multiple sources of data, and complex validation procedures that signaled the probability of fraud.

• Created multiple validations, integrating multiple datadources, to detect fraud.
• Worked on cross-functional teams, onboarding new team members and fostering a collaborative team culture
• Our software was capable of identifying and alert to stop the spending in the early stages of the fraud
• Won the 2023 “Reconhe-Ser” Award, a yearly award the TCU gives to projects that most impacted the capability and speed of the court on catching irregularities.

DevOps & Security

Brazilian Federal Court of Accounts (TCU)

As a member of the newly created DevOps Team, I was responsible to find, eval and mitigate vulnerabilities in our codebase. I've evaluated tools, added them to our CI/CD Pipelines, and helped teams mitigate their vulnerabilities

• Spearheaded continuous integration by migrating over 100 Jenkins jobs to a new CI/CD pipeline using Jenkins Pipelines as code.
• Added new tools to identify vulnerabilities
• Partnered with infrastructure teams to optimize deployment and monitoring of applications.
• Fixed many vulnerabilities that could have caused great damage to our organization

Java Development

Brazilian Federal Court of Accounts (TCU)

As the lead developer for a key project tracking government personnel records, I designed and implemented complex validation systems that saved thousands of hours of manual auditing.

I led cross-functional teams, mentored junior developers, and consistently drove the adoption of best practices in software engineering.

• Led the development of over 500 validations, ensuring legal compliance for government documents using Java and Spring.
• Interviewed, mentored and trained junior developers and onboarded new team members, fostering a collaborative team culture.
• Led the development of projects to identify irregularities in government procurement processes, reducing audit times and improving accuracy.
• Won the 2021 “Reconhe-Ser” Award, a yearly award the TCU gives to projects that most impacted the capability and speed of the court on catching irregularities.

Mobile Development

rotasPsi

Developed and launched mobile applications for iOS and Android from scratch for a fast-paced startup, focusing on user experience and seamless performance. I provided technical guidance and advised on backend architecture, significantly contributing to the startup’s initial product launch.

• Developed and published iOS (Swift) and Android (Kotlin) apps from the ground up.
• Implemented key features such as user authentication, push notifications, and data synchronization, significantly improving user engagement and retention.
• Collaborated closely with cross-functional teams to ensure features aligned with business goals.
Advised on backend technology selection and interviewed potential candidates, helping shape the technical direction of the startup.

Digital Signatures

e-Sec Digital Security

Worked on backend development and mobile applications, focusing on security solutions. I led the transition from outdated technologies to modern solutions, including the migration of a legacy applet to a client-installed app and the development of a new cryptographic library.

• Created and mainteined their CI/CD infrastructure (Jenkins, Nexus and SonarQube)
• Led backend development with JBoss and Spring Boot for multiple projects in digital security, including one that was implemented in the Brazilian Army and another at the University of Brasilia.
• Migrated a legacy Applet for digital signatures to a modern client-side application, improving security and usability.
• Maintained a cryptographic library, including adding support for PAdES (PDF Advanced Electronic Signatures).
• Lead efords to keep an Agile Insfrastructure, wish scripts to create VMs (Vagrant) and Containers (Docker) automaticaly.
• Maintained and improved the iOS app written in Objective-C.
• Led efforts to improve app security by implementing encryption protocols and ensuring compliance with industry standards, using the cryptographic library I maintained.

Internships

multiple companies

During my internships, I gained foundational experience in software development, CI/CD, and agile processes, working with various teams to support and improve enterprise-level applications.

• Contributed to software architecture by implementing key CI/CD processes using Jenkins, JBoss, and SonarQube.
• Gained experience in Java, JSP/JSF, and backend technologies, contributing to multiple projects.
• Assisted in automating build and release pipelines, resulting in faster deployment cycles and reduced manual effort across the organization.
