The most amazing...

...challenge I've taken over is the development management of a terribly written logistics system for oil and gas, making it work well and evolve.

Work Experience

Lead Developer

2012 - 2018
Tecgraf Institute, PUC-Rio
  • Took over the development of a large, poorly regarded, poorly written third-party logistics system for a large oil and gas company.
  • Refactored, re-wrote, and documented several parts of the system.
  • Fixed countless pre-existing bugs, often by rewriting entire portions of the code, substituting it with clear, robust solutions.
  • Made the system resilient and fail-resistant in an inhospitable environment, reading from and writing to other systems filled with data inconsistencies and frequent unannounced interface changes.
  • Made huge improvements to performance through query adjustments, proper use of caching, UI optimization, and changes to the architecture.
  • Developed an excellent relationship with both clients and users, who began to trust us and request new features for a system they had previously given up on.
Technologies: SQL, RMI, Swing, Spring, Hibernate, Java EE, Oracle, Java

Candidate Evaluator

2011 - 2018
Tecgraf Institute, PUC-Rio
  • Integrated a small group of developers and managers responsible for evaluating candidates for positions in the Distributed Systems group of the Tecgraf Institute.
  • Helped create the candidate evaluation process still in use today.
  • Conducted dozens of candidate interviews and assessments.
  • Evaluated dozens of candidate sample projects and led project assessment interviews.
  • Had had a high rate of success hiring productive, high quality, motivated professionals who have contributed positively to our team.
Technologies: Confluence

Senior Developer

2005 - 2011
Tecgraf Institute, PUC-Rio
  • Helped create and develop three separate logistics applications for a large oil and gas company, responsible for oil allocation, import/export of oil and oil products, and inventory of oil and oil products. All three systems are in production to this day and have a large demand for continuous evolution.
  • Quickly rose in trust and responsibility within the project, often splitting management tasks with the project manager.
  • Worked on every aspect of the projects, from the database to the UI, and from the build configuration to continuous integration.
  • Integrated application data with a solver written in C++ using OCCI.
  • Created several reusable components and APIs that have been used in many of the institute's other projects since.
Technologies: Stored Procedure, SQL, Oracle, Ant Design, Hudson, OCCI, C++, RMI, Swing, Java
