This strategic project aimed to eliminate manual workflows in the HR department related to employee movements—such as promotions, transfers, and contractual changes—that were previously managed entirely through Excel spreadsheets.

The new platform introduces a centralized and automated solution, enhancing control, auditability, and collaboration across departments involved in workforce management.

Technologies used in development:

• Angular 11 – Front-end SPA to handle workflows, validation, and -friendly navigation.
• Java 11 → 21 (in progress) – Modernized backend stack during project evolution.
• Spring Boot 2.7 → 3.2.11 – Gradual migration aligned with Java version upgrade.
• Microsoft SQL Server – Modeled and maintained relational schemas for HR records.
• JUnit & Mockito – Coverage for business rules and service layer logic.

Infrastructure & DevOps:

• Google Cloud Platform (G) – Application hosted with scalability and security in mind.
• Jenkins – CI/CD pipeline integrated with SonarQube and Veracode.
• Docker & Kubernetes – Containerization and orchestration of services.
• Bitbucket – Source control and pull request workflows.
• Jira & Confluence – Project tracking and knowledge documentation.

My responsibilities as Tech Lead:

• Designed the system’s architecture and ed database modeling with the data team.
• Built core backend services and mentored developers on best practices.
• Acted as a bridge between business and tech, helping define HR rules and translating them into scalable APIs.
• Helped unblock team during development and ensured delivery consistency.

Benefits & Outcome:

• Replaced a fragmented Excel-based process with a secure, centralized digital solution.
• Reduced error-prone operations and manual rework.
• Improved traceability and audit control of employee-related changes.

This project aimed to modernize the way ing s were managed within the Risk domain by developing a new web-based CRUD portal. Previously, key procedures contained hardcoded values, leading to high maintenance effort and limited flexibility.

The new system enabled autonomous registration through a -friendly interface, removing the dependency on manual database intervention and reducing operational risks.

Technologies used in development:

• Angular 11 – Built the front-end for CRUD operations with form validation and responsive layout.
• Java 11 + Spring Boot (2.7.18) – Developed the backend API with domain services and repository layers.
• Maven – Dependency and lifecycle management.
• Microsoft SQL Server – Used as the primary data store for s and metadata.
• JUnit – Ensured unit testing coverage for critical components.

Infrastructure & DevOps:

• Google Cloud Platform (G) – Entire infrastructure hosted for scalability and reliability.
• Bitbucket – Source code repository and branch management.
• Jenkins – CI/CD pipeline integrated with SonarQube (static code analysis) and Veracode (security scans).
• Docker & Kubernetes – Containerization and orchestration of the application.
• Jira & Confluence – Used for task tracking and project documentation.

Benefits & Outcome:

• Eliminated hardcoded logic from PL/SQL procedures.
• Enabled autonomous and centralized management of ing s.
• Reduced maintenance time and increased system reliability.
• Improved code quality and security through automated pipelines.

This innovation marked the initial phase in creating a robust application capable of generating an Excel file with all the information needed by the end .

Technologies used in development:

• Datastage: Employed to read operations and store them in a dedicated database.
• Angular: Front-end components were repurposed.
• Java + Spring Boot: Implemented new features to read and transform data into a CSV Excel format.
• JUnit: Ensured code quality and the overall integrity of the API.

The project also incorporated:

• Jenkins: Automated builds.
• Sonar: Enhanced static code analysis.
• Nexus: Artifact management.
• Jira: Tracking and reporting issues.

Infrastructure:

• GKE (Google Kubernetes Engine): Hosted the application for seamless deployment and scalability.
• Dedicated server for Datastage: Ensured optimal performance and reliability for handling operations data. Mostrar menos

I worked in a significant role in a technology migration project, which involved the transition of legacy robot. This robot was responsible to searching informations in WSDL and converting data into an Excel spreadsheet.

I worked in a significant role in a technology migration project, which involved the transition of legacy robot. This robot was responsible to searching informations in WSDL and converting data into an Excel spreadsheet. I`ve used an advanced solution and most up-to-date solution such as Spring boot and REST architeture to convert xml data into JSON. It is now available through an API.

It was developed using the following technologies:

APIGEE: To manage, to monitor and expose the API, ensuring security and scalability.
Spring Boot: Used to develop a high-quality, fast and efficient API application.
Apache Camel: The best solution for integrating and routing between components.
Junit: Ensuring code quality and the overall of tthe API.

This project also included:

Jenkins: to automate builds.
Sonar: For better static code analysis.
Nexus: artifact management.
Jira: tracking and reporting issues

With this well-executed migration we were able to modernize the entire system, improve performance and make future maintance easier. I'm very proud to have participated in this technological transformation applying the best practices and cutting-edge technologies Mostrar menos

Project responsible to automate the process called circularization letters. We automated all manual and process of area. s were responsible for collecting informations from the other areas, checking it and then creating a pdf file to send to the auditors through an online application.

Before this project, the s needed to make The whole process manually. Part of this project was created an angular application, using dynamic forms, to show a list of contents and file to make a on the screen or create a new requests through the system.

On the other side was created some API’s to automate this process, which means, create a request, edit informations, generate pdf files and finally integrate with another Api called, Confirmation.

In this project some meetings was done with confirmation team in USA. I coordinated this meeting talking about the project, our needs and what was required to o make things work.

The entire communication with the team abroad was done in English, including exchanging emails.

Technologies and frameworks:

Angular and Jest.
Spring Boot, Apache Camel and JUnit.
SQL Server.
Google cloud Plataform, PUBSUB and APIGEE.

Jira, Bitbucket and Git.
Jenkins, Sonar and Veracode.

English for business and meetings.

Migration project from Sybase to sql server 2016. Changes were made to a batch process, which automatically changed s for service s. This process performed the connection via sybase. However, it was necessary to make changes to the process as a whole because the migration required an Always On connection. This connection was made in the sql server 2016 and had as premise to update (Exec procedure) the data in the secondary instance and perform the update (actual update) in the main instance. In this way, the other Always on instances would be updated automatically.
