During international projects in Brasil, India and Germany I aquired extensive experience in complex multi tier JEE projects. When working as architect or team lead, I always like to be involved in hands-on development.

Living in Brasil for over 15 years, and Argentina for a year, I have a thorough knowledge of the south-american culture.

Magazine Luiza – São Paulo, Brasilien (Retail)
Role: Scrum-coach, Lead-Developer/Architect

With my experience as scrum coach and developer, I helped to form several development teams, as lead developer, from interviewing new developers during the hiring process to training them regarding code quality, clean coding standards, and automated testing techniques. I introduced testing tools like Junit tests, Arquillian-based integration tests, Cucumber-JVM based BDD tests and helped introducing code reviews and pair programming.

Currently I am working in a project that consists of the development of an engine that imports xml-based invoices from a SOAP web service. The invoices are checked against consistency and then automatically integrated into the companies ERP.

The architecture is based on Rest-Microservices, with an Angular 2 SPA client for monitoring purposes.

Technologies used: Oracle Virtual Box, Docker, JEE, Eclipse, Git, BitBucket, Gitflow, Jenkins, JBoss/Wildfly, SpringBoot, Spring Data, Arquillian, REST, SOAP, Oracle 11g, Oracle SQL Developer, AngularJS 2, AWS.


5.2015 – 8.2015
Santander São Paulo
Role: Scrum-coach, lead developer

Development of a PMO reporting tool

This was the first project where I had the opportunity to test scrum in a project that was failing at the traditional waterfall approach. Even being co-located at the client, it had failed, after more than 6 months.

I was first called to help as a developer. The more I learned about the project, I realized that the team had to be reorganized and scrum would be a perfect fit: the team was co-located with the client.

I decided to use short iterations of one week for fast delivery of business value as working product increments. This gave us the opportunity to regain the client's confidence by showing working software - even if delivered in small steps. It was not possible to implement all the scrum ceremonies (no regular sprint retrospectives), because of the initial resistance of the team and a project manager (who considered it a lack of time). In spite of the team's resistance, I succeeded in introducing test automation, little by little. One big issue was a huge technical debt, which was necessary to be addressed.
I had the opportunity to strengthen the teams pride by letting the developers take responsability, and by conducting code reviews (together with refactoring techniques), helped to create an awareness for code quality.

The biggest challenge was convincing the project manager to let go of control and let the team organize itself. After some iterations results appeared and the pressure gradually subsided. I had to leave the team after 4 months to join Magazine Luiza. The project was finished after 8 months to the full satisfaction of the client, and a new contract is being negotiated.

06.2014 – 12.2014
GLS with Lufthansa Systems
Role: Technical architect

Validation of the architecture of the target system, that was defined to replace a set of legacy applications. The target system consists of a distributed multi-tier application of three physically separated layers. The first layer is an independent SOA, that encapsulates the legacy data sources, accessible via a REST API. The middle layer is responsible for the synchronization and control of the estimated 5000 clients. The synchronizaton technology used is SymmetricDS.
The clients are JavaFX thin-client applications, communicating via a dedicated REST-API with the local backend.

My activities consisted of validating the results of the business analysis, transforming the business data model to a technical JPA data model for implementation. In the second phase of the project, I worked as the technical architect, formulating the technical architecture. I was responsible for the creation of the technical domain data model, based on JPA, as well as the design of the REST-APIs of the JavaFX client facing the local backend. I was also responsible for the application design of the local backend and participated with the implementation of the technical POC.
