I am a programmer with several years of experience in the development of web applications, participating in authentication projects, creating libraries to read database changes through the WAL (postgres) for different purposes such as logical replication between databases or sending of changes to destinations like kafka, I have participated in migrations between monoliths to microservices, database migrations, implementation of Akka clusters, implementation of API gateways for authentication purposes and fault tolerance between apis, using different programming languages such as scala, rust, java , kotlin, go, php, databases like Postgres, documentDB, DynamoDB, redis, streaming platforms like kafka, queues like sqs, activeMQ. I also know AWS, architecture, and patterns. I have had a lot of problems in development and production environments and I think I have learned a lot about them, for example, I have learned some things that I should do and others that I should not do if I want my system to scale. I also know that there is still a lot to learn.
