I joined Pingvalue in the first months helping to define workflows, technical requirements, and tasks from high-level requirements on a SCRUM-based development using Jira and Confluence.

We built the platform around the API following the RESTfull principles, using Test Driving Development and Continuous Integration.

We migrated the legacy API removing Google App Engine code dependencies and building a new infrastructure in Kubernetes, allowing us to have more flexibility and proper environments for development, acceptance, and production.

As a startup, we built a strong and collaborative team of over 20 developers that supports frequent releases over 3 different platforms, web, iOS, and Android.
