A little about my journey...

I am a Technical Lead and Software Engineer with more than 14 years of experience in the technology and development area. During this time, I worked in different companies, in three different countries (Brazil, Portugal and France) with different types of projects and challenges that shaped me into the professional I am today.

Over the years, I have acquired solid experience in backend development, working on the design and implementation of scalable, resilient and high-performance systems. I have gained experience in languages ​such as Python and mainly Java, a language in which I obtained professional certification with a strong emphasis on relational and non-relational databases. I actively participate in architectural decisions, from the definition of microservices to the choice of technologies and asynchronous communication standards. I have deep knowledge of best practices in API design, messaging, caching and scalability strategies. My focus is on high-impact deliveries, with an emphasis on performance, security and maintainability.

Areas of activity



• Architecture
• Solid experience in implementing microservices-based solutions. Throughout my experience, I have dedicated myself to create scalable, resilient, and completely decoupled systems, always focusing on continuous evolution, ease of maintenance, and alignment with business needs. To ensure a high degree of independence between services and facilitate asynchronous communication, I widely use Event-Driven Design practices, which has been essential in defining architectures that prioritize flexibility, reactivity, and low dependency between domains. This approach allows services to communicate through events, promoting greater autonomy, observability, and adaptability of the ecosystem as a whole.
  
  In addition to the architectural vision at the distributed system level, I also work on the internal organization of applications, adopting approaches such as Clean Architecture and Hexagonal Architecture with a strong focus on the separation of responsibilities, inversion of dependencies and orchestration of decoupled components, ensuring testability, flexibility and easy maintenance throughout the software life cycle.
  
  
• In-depth experience in applying classic and modern Design Patterns as fundamental tools to solve recurring architectural problems, always guided by SOLID and OOP principles and good engineering practices.
  
  
• Database performance and optimization
• I worked on some projects where the objective was database optimization and performance, working on the planning and continuous improvement of high-demand systems, in selecting the ideal type of database for each scenario, with expertise in relational solutions (PostgreSQL, MySQL, Oracle and MSSql), NoSQL (ElasticSearch), and in-memory (Redis, Memcached).
  
  Working on database systems with ElasticSearch, I was officially certified as an Engineer by Elastic. I have expertise in designing, optimizing and maintaining Elastic clusters in high availability environments, focusing on search performance, relevance and scalability, and also in integrating Elasticsearch into microservices-based architectures.


• Solutions based on message queuing
• Solid knowledge in the application of distributed messaging solutions, with practical experience in projects using Apache Kafka, Amazon SQS or Amazon MSK.
  
  Works on the design and implementation of event-driven architectures, with a focus on service decoupling, resilience, and scalability. Expertise in topic configuration, partitioning, consumer groups, and message delivery assurance with Kafka, as well as in the use of SQS to orchestrate asynchronous flows, FIFO queues, and dead-letter queues. Committed to building robust and efficient systems in distributed and highly concurrent environments.

In projects using Apache Kafka I always try to apply some Apache Kafka Patterns to obtain better results.


• Cloud infrastructure and CI/CD solutions
• Experience in architecture, development and deployment of cloud-based solutions, with a focus on AWS. Throughout my career, I have worked directly on the design and operation of scalable and resilient environments using EC2, ECS, EKS, S3, SQS, MSK, Lambdas, OpenSearch, Rekognition, among other AWS services. I have mastered the creation and maintenance of CI/CD pipelines with CodeBuild, CodeDeploy and CodePipeline, optimizing continuous delivery flows and promoting greater agility in development cycles.
  
  In addition to technical issues, I also worked in some cases on cloud cost management, applying optimization strategies, instance reservation and efficient use of resources, always focusing on reducing waste and ensuring the best cost-benefit of production solutions.
  
  Obviously I'm not a devops, but whenever I had challenges to overcome related to cloud infrastructure I was able to accomplish them.


• Monitoring
• I have extensive knowledge in system monitoring and observability, ensuring the delivery of stable and high-performance services. I have extensive experience implementing solutions based on Elastic Observability, Prometheus and Grafana, providing real-time visibility into critical metrics and facilitating the rapid identification of anomalies. In addition, I use CloudWatch to consolidate cloud infrastructure metrics, ensuring a unified overview that supports agile decisions about scalability and resource allocation.
  
  In the scope of logging and log analysis, I master the use of ElasticSearch, Logstash and Kibana to build robust pipelines for data ingestion, indexing and visualization. These tools allow me to significantly reduce the average time to resolve incidents and create customizable dashboards that support both technical teams and business stakeholders. In parallel, I apply Google Analytics and Firebase Performance Monitoring to capture usage and performance insights in web and mobile applications, optimizing the user experience and aligning technical metrics with business indicators.
  
  I also work with Crashlytics to monitor failures in real time, helping to prioritize bug fixes based on impact and frequency. This combination of tools gives me the ability to anticipate issues before they impact users, improve system reliability, and foster a culture of continuous improvement, always focused on maximizing availability, reducing operational costs, and consistently delivering value.


• Tests
• I have extensive experience as a software engineer with a focus on quality and test automation. Throughout my career, I have implemented and managed comprehensive strategies for unit, integration, functional, API, performance, acceptance, security, contract and interface testing, ensuring that each layer of the system was consistently validated. Thanks to this testing apparatus, I have achieved some very valuable cases, including:
  • Drastically reducing the number of bugs in production, increasing system reliability and user satisfaction.
  • Accelerating the development cycle, with rapid and continuous feedback to the team, which allowed for more frequent deliveries and faster time to market.
  • Standardizing processes and practices, promoting a "quality first" culture that facilitated the onboarding of new members and improved collaboration between development, QA and DevOps teams.
  • Mitigating risks in critical releases, anticipating potential performance or security flaws before they reach customers.
  • Optimize operational costs by detecting performance bottlenecks and resource leaks early, avoiding costly rework in production environments.
