Software Engineering Manager at Agreement Express from December 2020 to August 2021

Implemented, through the application of Software Engineering practices, the mechanisms to quantitatively manage the quality of releases/deliverables so that it could become a manageable performance indicator and apply techniques of defect avoidance (avoid introducing defects as opposed to trying to identify them later), which was carried through with the implementation of measurable quality indicators, non-functional requirements definition and defect origin analysis.

Promoted the definition of a development process as a tool to standardize the development practices and make the performance outcomes more predictable, plus significant contributions to development practices, defect prioritization techniques, and technical debt management.
