Senior Software Enginer  •  C6 Bank

[Tech Engineering Specialist] As part of the CRM team, I'm responsible for keeping products running with a large number of customers (over 20 million). I am also responsible for leading the team through our challenges, evaluating the best approaches and solutions. Here are some highlights:

• I developed a green field application ecosystem that allows over 100M daily requests to access dynamic user data, with a really short response time, using cache and asynchronous processes.
• I scaled an application using code skills. Refactoring, best practices approaches and the latest language tools, such as thread poll, coroutines, scaling with message broker and cache memorization.
• I improved the response time of a sensitive Rest API from 2sec to 200ms using DB data access optimization. I implemented the concept of Data Base partitioning and data purge.
