I actively participated in the development of a complex White-label system, focusing on building a scalable RESTful API with Nest.js. The solution's architecture included managing asynchronous queues using BullMQ. I was responsible for implementing a granular and customizable authentication and permission system, integrating with external APIs for payments, and developing a feature for data upload via spreadsheets. The entire infrastructure was orchestrated with Docker, and the teamwork followed the SCRUM methodology, managed on the monday.com platform.

I worked on the development of a complete solution, building a robust RESTful API with Nest.js. The system's architecture used RabbitMQ for managing queues and asynchronous tasks. Concurrently, I developed a Bot for Discord and created responsive front-end dashboards and pages with React, focusing on SEO optimization. All work was conducted collaboratively, applying the SCRUM methodology and using the Linear platform to ensure agile and efficient deliveries.

As a backend manager, I took on a leadership role that greatly assisted in my career growth. In this role, I gained extensive experience in developing RESTful APIs using Node.js, TypeScript, Prisma ORM, PostgreSQL, Docker, Swagger for documentation, Zod for validations, and Jest for test creation. As the leader of the backend team, I was responsible for training team members in SCRUM methodologies, programming logic, and API development using the mentioned technologies.
