Renato B.

Vetted Back-End developer in Brazil (UTC-3)

I'm a backend software engineer working primarily with Python. I see software as a tool to solve problems, instead of the goal in itself. Sometimes it's necessary to compromise software quality perfection in favor of other goals and needs. When this is the case, I strive to make trade-offs conciously and judiciously. My background involves building products with complex third-party API integrations, large scale data processing and ETL jobs, dealing with unstructured data sources, implementing automated unit & integration testing. I also have experience with implementing AI/ML models and libraries, especially LLM and NLP-related. AWS is the cloud provider I have most experience with, in both traditional architectures using EC2, RDS, ELB, etc, as well as serverless architectures using Lambda, API Gateway, DynamoDB, Aurora Serverless, S3, Kinesis, Athena, etc.
