DELOITTE
At Deloitte, I led and contributed to the development of multiple technology solutions for clients across various sectors, including public transportation, automotive, healthcare, energy, and public administration.
I was responsible for the deployment and evolution of Liferay-based portals (CE 6.2 and 7.4), leading teams of up to five people and managing integrations with external APIs. I designed modern microservices architectures using Quarkus, migrated Java EE and Spring Boot applications, and implemented authentication systems with Keycloak, along with reactive solutions using Mutiny. I also integrated messaging systems (Pub/Sub), monitoring with CloudWatch, and advanced testing practices with JUnit 5.
Additionally, I led the development of workforce planning applications for a company in the industrial/automotive sector, using Node.js and React, ensuring alignment with real business needs.
I contributed to the development of internal applications for healthcare organizations using Angular and Spring Boot, as well as the maintenance and evolution of web platforms for energy sector companies using Drupal.
Furthermore, I worked on the maintenance and continuous improvement of web applications for public sector organizations, handling issue resolution and functional enhancements.
All projects were delivered following Agile methodologies (Scrum), promoting collaboration and continuous value delivery.
Sonicon Systems
At Sonicon Systems, I worked as a Liferay developer, simultaneously handling multiple projects. I developed web portals from scratch using Liferay versions 6.2, 7.0, 7.2, and 7.3, and was also responsible for resolving technical issues reported by clients. My role combined development, customization, and support to ensure stability and continued improvement of the deployed environments.
Rob Surgical
I worked as a computer vision developer, designing an application capable of detecting specific tool components using an algorithm developed in C++. The project focused on achieving high visual recognition accuracy in demanding technical environments.
Accenture
At Accenture, I contributed to the development of technology solutions focused on both internal applications and proof-of-concept initiatives for clients across various sectors, including public administration, financial services, and applied research environments.
I developed reinforcement learning (RL) algorithms in Python to support decision-making in complex scenarios, as well as natural language processing (NLP) solutions for analyzing unstructured data such as social media content. These developments were primarily carried out in prototyping and technology validation contexts.
I also contributed to the maintenance and evolution of internal applications deployed in cloud environments using Kubernetes on Azure, ensuring stability and continuous improvement.
Additionally, I worked on data analysis applications for public sector organizations, building interactive visualizations (maps, charts, and electoral analysis) using R and Shiny, combining statistical analysis with advanced data presentation.
In the financial sector, I participated in enterprise system integration projects using ServiceNow, as well as in the development of blockchain-based proof of concepts using Hyperledger Fabric and Vue.js, exploring innovative use cases in corporate environments.
Indra
At Indra, I contributed to data analysis and transformation projects for a company in the consumer goods sector (food and beverages).
I evaluated specialized tools for database migration processes, such as Database Conversion Workbench and Ispirer, performing comparative analysis to optimize system conversion and modernization strategies.
I also worked on data analysis using tools like QlikView and Oracle, enabling data-driven decision-making and improved information insights.
Additionally, I designed data integration flows using Informatica PowerCenter, contributing to the improvement of ETL (Extract, Transform, Load) processes, ensuring higher efficiency and data quality.
