Responsible for the development of the "Rhiscom Pay" microservices group, a middleware created to establish communication between the ELERA Point of Sale System (Toshiba) and the Giftcard authorization system (Bopos Cloud) for the management and use of Giftcards as a payment method.Main activities:- Creation and integration of Spring microservices (Discovery Server, API Gateway, Giftcard Service).- Implementation of secure communication using SSL certificates with Mutual TLS between the microservices and the external connector (Payment Connector).- Consumption of Bopos Cloud API using OpenFeign.- Dockerization and deployment of microservices.- Management of container images in Azure Container Registry.- Deployment of images in Kubernetes pods in Azure AKS.

As a leader and strategist in the development and enhancement of the ATN Tool (Regression Testing Automation Tool for Retail Point of Sale Systems), I have orchestrated the planning and execution of key initiatives that have revolutionized the efficiency and operability of the tool. Here are some highlights of my contributions:Implementation of text pattern recognition (OCR) validations, an innovation that added flexibility to validations and improved adaptability to changes in the user interface, ensuring more robust tests and less susceptibility to modifications.Implementation of bulk test case editing, recognizing common variations in multiple outputs of cases even with different execution flows. This has optimized the time and resources needed to maintain the robustness of test cases given the dynamic deployment processes of retail software.Implementation of Android device emulation for payments from applications with QR codes and security tokens, enabling the automation of tests for omnichannel applications.Implementation of TDR emulator for QR code scanning as a data source, consolidating our position as a comprehensive tool for testing in retail environments.

Improvements and new functionalities to Automaton, a tool developed in Java, designed to run regression tests at point of sale systems in national and international retails (Walmart Chile, Walmart Mexico, Sodimac, Grupo Éxito Colombia, Belk USA, Liverpool).

Development of ATN-WEB, tool created to perform regression tests on websites over different browsers (Chrome, firefox, Edge), developed in JavaScript (Angular7 for the Front, nodejs for the Back):* Integration with selenium webdriver.* Integration with selenium Builder for test cases record.* Application development to manage test cases automation, script management, user access control, dynamic data management for executions, report generation.* testlink integration as a test case management tool.* Mantis Integration as issue report tool.

- Leadership of the work team.- Monitoring and support of Yattsi native application and moderator application in NodeJs.- Integration of payment gateway (BrainTree) in the application.- Capital raising meetings with Venture Capital companies.

* Development of android native application (Yattsi): - Integration of social register (google, facebook). - Integration of webRTC library for calls (opentok). - Addition of device resources (microphone, speaker, camera). - Integration of payment gateway (Realex Payment).* Deployment in PlayStore of the application.* Support and integration of new features.* Development and deployment of NodeJs application used to moderate webRTC call's flow mades through the YATTSI application.

Development of Yattsi application' hybrid version: Application created for real-time Interpretation service through webRTC calls. Developed with Ionic over angularJs.

* Optimization of current system functionalities and addition of new functionalities.* Design of the new visual distribution of the website content, mobile and desktop.* Collaboration in the resolution of issues and optimization of some functionalities in BackEnd (Java).
