Previously, the manual process involved various departments, each one with a different SLA. This automated process reduced from various weeks to create the marketplace in just a few minutes.- I developed various features in administration GraphQL for white label e-commerce platform that allows companies to link their loyalty programs to the creation of their marketplace, generating credits in points or cashback for their consumers. In the administration area, the user would choose the e-commerce partners and the percentage of the cashback using .Net 3.1, HotChocolate (GraphQL), and MongoDB. CI/CD pipeline with Azure Repos deployed in Azure DevOps. The platform is part of Vertem’s portfolio of solutions to retain and engage consumers, business partners, and employees in a single environment. The platform received an investment of more than R$15 million and was developed to offer the market a new possibility of relationships between brands and consumers.- I developed Azure Function (HTTP) using .Net Core 3.1 with MongoDB that receives the transactions from third-party payment API to identify customer´s information and add to the transaction processing queue.- I developed Azure Function (queue) using .Net Core 3.1 with MongoDB that processes cashback of all the e-commerce to credit the customer´s account into fidelity/loyalty points. This is the most crucial and critical process of the transactions.

- I designed, created, and developed the REST APIs in microservice architecture in .Net Core 3.1 with SQL Server (Entity Framework Core), Health Check, Swagger, Azure App Insights (monitoring), and Azure Service Bus (messaging) for the MVP of an agricultural credit platform for modern agribusiness, which connects the rural producers that seek alternatives for crop financing to financial agents. It facilitates and optimizes credit for distribution, all in a personalized, secure, modular, and scalable way. The platform takes care of the financing and credit process all in one place.- I did all the requirements gathering and analysis for all the features.- I created all functional specification documents and UI prototyping.- I planned and created the tasks schedule.

- I developed new features for order REST API for auto parts e-commerce platform in microservice architecture (DPaschoal) in .Net Core 2.1 with Entity Framework Core, Health Check, Swagger, and SQL Server hosted in Azure with Azure Kubernetes Services (AKS) for orchestration of Docker containers and Azure Service Bus for messaging.- I designed and developed script automation using Azure Automation to schedule the increase and reduction of DTUs of the Azure SQL, saving resources and money for DPaschoal.

– I designed REST APIs for processing CDR Billing files using ASP.NET Core Web API, MongoDB, RabbitMQ, IdentityServer 4 (Identity and Access Control), Ocelot (API Gateway), and Elasticsearch (Logging) and Git/SVN. Each step of the process was broken down into a microservice with its well-defined boundary context allowing improved scalability and better fault isolation.– I developed new features for case management web application using PHP, AngularJS, and jQuery with Oracle 12c with Agile Scrum methodology.

- As a software engineer, I developed new features for CPFL Energy Group's commercial and field maintenance service orders management application.
