Experience

Sonatafy Technology

  • SaaS DB Complex Query Optimization – Worked implementing a custom approach to optimize concurrent complex user queries, reducing 10 times original query execution time and previously perceived SaaS DB quota.

  • Unit Testing Methodology Unification – Established a frontend testing pattern using both Enzyme and React Testing Library on recent and legacy codebases, improving readability, DX and creating a common understanding among developers on how to create unit and integration tests for each component and feature.
  • Fixed Backend Testing Suite Flakiness – Refactored the codebase and setup of a JUnit testing suite that was part of a backend service built with Dropwizard, the suite throwed random false negative assertions due to async calls to H2 Mock DB and wrong data isolation for each test.
