Can you tell me about a project you are proud of?

Im most proud of one of my recent projects - architecting an event-driven system for caching analysis outcomes, building a microservice to vend the outcomes while also migrating existing data from DynamoDB to OpenSearch.

Reasons:

1. The existing data model was limiting in that it was not extensible to cache other NLP analysis  outcome except translation for which it was built initially. This made the system not usable for other newer use cases. I designed a new data model that was generic and extensible to other analysis and allowed caching of other results

2. Opensearch was a technology unfamiliar to our team and it involved a steep learning curve for me and other people who worked on the project. I made sure I documented any new learnings/choices so it was easier for the other team members to pick up and work on it. I setup separate sessions with the other 2 engineers who worked on it to go over some details like VPC, how private links are setup etc to unblock them

3. I setup CI/CD pipelines and automated testing.

4. Setup metrics and alarms through Infrastructure as code

Result:

We were able to launch the project within tight deadlines
