Squadra•  November 2022 - September 2023
Worked on developing API in RESTful using Golang and the Gin framework to define routes, to support the management of charter trips between companies and truck drivers in a microservices environment. Performed both internal (databases, other services) and external integrations (third party) services Implemented new features and functionalities in the existing microservices architecture using Go language. Worked with MongoDB as a database to store and retrieve data by creating queries. Integrated communication between microservices using REST and gRPC protocols for efficient and reliable communication between services. Collaborated with the team to analyze requirements, design endpoints, and ensure seamless integration with other services. Optimized endpoint performance by implementing caching mechanisms, query optimizations and efficient data recovery techniques. Conducted thorough unit testing and debugging of endpoints to ensure their functionality and stability. Participated in code reviews and provided constructive feedback to improve code quality and maintainability. Deployed the project in a production environment and actively monitored its performance and stability. Use of JSON to exchange data between different application components.
