Over five months, contributed to LerianStudio/midaz by building and enhancing backend systems focused on API reliability, observability, and data integrity. Developed and refactored RESTful APIs using Go and PostgreSQL, implementing features such as portfolio-scoped account management, soft deletion, and modular cursor-based pagination. Introduced distributed tracing and telemetry with OpenTelemetry, integrating context propagation across RabbitMQ, Redis, and service layers to improve monitoring and root-cause analysis. Strengthened data security through masking and validation, modernized dependencies, and expanded Swagger documentation for clearer onboarding. The work emphasized robust error handling, test coverage, and maintainable code, supporting scalable financial services and developer productivity.
