I provided software engineering services to KrakenFlex on a contract basis.
I worked in Python with asyncio, on serverless AWS with Lambda, SAM and CloudFormation, DynamoDB for storage, and SNS and SQS between services.
Event-driven services talking to each other over SNS and SQS are straightforward to reason about one at a time and much harder to reason about together, which is a large part of why I later built a local AWS simulator for testing this kind of system.
If you have event-driven AWS services that are hard to test together, that’s a problem I’ve spent a lot of time on. Get in touch.
