I designed, developed, and tested and currently maintain the following open-source microservices:- carbonio-files: a Java17 backend service to upload, download, manage, and share files and folders. This was my first big project, which I built, and I decided to use GraphQL to expose APIs to manipulate the metadata of the items and REST APIs to upload/download files. With this project, I learned a lot of new things and delved deep into the Netty and GraphQL rabbit hole. I also understood the main advantages, problems, and criticality in a microservices system.- carbonio-user-management: a Java17 backend service to expose Zimbra SOAP Account APIs as REST APIs. The main goal is to let other microservices interact with Zimbra account information without using the SOAP. This project has a dynamically generated SOAP client based on the schema using the jaxws-rt library, and the REST APIs are built using the RESTEasy framework.- carbonio-docs-connector: a backend built in Java17 to integrate Collabora Docs Editor (LibreOffice online) into Carbonio. Using RESTEasy, it exposes WOPI endpoints necessary for Docs Editor to interact with carbonio-files to download and upload versions of an open document. One of its scope is to be a middleware in order to not expose Docs Editor directly outside the proxy for security reasons.Each microservice has the following characteristics in common:- The development is done following SOLID, DRY principles and a clean code approach for maintainability, extendability, and readability of the codebase- The APIs are defined in accordance with the team responsible for building the client that uses them (both frontend, backend, and mobile). The REST APIs are defined using the OpenAPI 3 schema, and the GraphQL one using the latest specifications- I used Mockito, JUnit5, Testcontainers, and MockServer libraries to implement unit and integration tests- They are connected and interact with each other through the Hashicorp Consul mesh network

I supervised and co-authored the development of carbonio-preview a Python backend microservice to convert potentially any type of documents into images/PDFs. The technological stack is composed of FastAPI to build and expose the APIs, Pillow for image manipulation, pypdfium2 for PDF generation and LibreOffice for document conversion.~~~At the moment, I am developing carbonio-load-testing: a Python project based on the Locust tool that allows:- populating the Carbonio environment- creating dynamically (using a YAML file) scenarios needed to be tested (for example, testing a client having a lot of users using a specific Carbonio module)- cleaning up the environment for the next testThe aim of this project is to allow each developer to easily extend it without knowing too much about Locust and keeping the project well organized by module. At the same time, a sysadmin can test some module of Carbonio or all of them thanks to a YAML definition file.
