At Llyner S.A.S, I design and deploy serverless backends on AWS, using clean architecture to organize production systems.
I architected an event-driven batch-processing pipeline with asynchronous workers, DynamoDB job-status tracking, and a dead-letter queue for failure handling.
I built and maintained 50+ REST endpoints in Python and FastAPI, and modeled DynamoDB data with single-table patterns and indexes for a production AI product.
I also implemented OAuth 2.0 and JWT authentication, provisioned AWS infrastructure with Terraform, and wrote unit and integration tests used as CI quality gates.
