Invoice issuing went from 20 minutes using human intervention, to fully automated, taking only 20s.# Team contributions- REST APIs best practices and Software Development best practices evangelist- Software architecture governance to improve software quality- Code review process to improve software quality and code ownership- Domain Driven Design encouragement to improve communication between business experts and the team

- By being part of an integrated team where business and tech work together for the overall evolution of a product called Energy within the Largest Bank in Latin America, I've been contributing with a dedicated and motivated team to achieve the most ambitious goals using AWS Infrastructure, Python and Angular as tools.- Electricity Trading is not a very simple process. There's an entire workflow to make it happen. The tech team is responsible for automating any process that demands time, effort or that is repetitive and complex. Our goals is to create tools or improve existing ones with modern software design, to make the Workflow simpler, faster and scalable.Back-office automation: Long term visualization of energy operations prices by providing up to date information about CDI (Interbank Rate) and USD 30+ years predictions.Back-office automation: Accounting process in seconds, trading operations calculated in less than 30s.What we use and practice:- API Owner: Evangelist of REST APIs best practices and API Gateway Governance- Test Driven Development is a habit, as well as Code Refactoring- Microservices is a must- Python is the main Language- Cloud Infrastructure using AWS- Principles we use on a daily basis: SOLID, CCP(Common closure principle), CCR (Common Reuse Principle), RRP (Reuse/Release Principle), SAP(Stable Abstract Principle), SDP(Stable Dependency Principle), ADP (Acyclic Dependency Principle)
