Top SchoolJuan Islas is a senior backend engineer with 6–7 years building serverless, microservices-driven systems for startups and large platforms across Argentina and remotely. He specializes in AWS serverless stacks (Lambda, API Gateway, Step Functions, DynamoDB, SQS/SNS) and infrastructure-as-code using Terraform, Serverless, SST and CDK, delivering resilient integrations for payments, CMMS and invoicing.
