Model Context Protocol server that lets coding agents drive a LocalStack container directly. Exposes tools for starting and stopping the stack, querying logs, listing emulated AWS resources, and running CLI commands inside the sandbox, so an agent can iterate on infrastructure code without leaving the chat.
Reference implementation of the Loan Broker enterprise integration pattern. A Step Functions workflow accepts a quote request, fans out to several mock bank Lambdas through EventBridge, aggregates the responses, and returns the best rate. Runs end to end on LocalStack with one command.
Quiz application that demonstrates a complete serverless stack on LocalStack. API Gateway routes traffic to Lambda handlers backed by DynamoDB, the static front end is served from S3, and questions are deployed with the AWS CDK so the whole thing comes up from a single cdk deploy.
Smart factory monitoring app that ingests simulated factory sensor data into Snowflake through S3 and Snowpipe, with dbt transformations orchestrated by Dagster. A Streamlit native app dashboard tracks machine health and anomalies, Snowflake Tasks trigger SES alerts for critical conditions, and zero-copy clones cover instant recovery. Local-only via LocalStack and the Snowflake emulator.
Storefront sample that wires together half a dozen AWS services on LocalStack. Cognito handles sign-in, products live in DynamoDB, images in S3, checkout goes through API Gateway to Lambda, and order events flow into SNS so a fulfilment Lambda can pick them up. Designed for live demos.
Full-stack survey application for internal use at Qxf2 Services. React on the front end, FastAPI on the back end, and Neo4j as the store so responses could be queried as a graph (employee, manager, project, sentiment). Deployed on EC2 with auth gated to the company directory.
Cloud emulator for AWS that runs the major services as local processes inside a single Docker container. Contributions covered README and contributing docs, CLI enhancements, community GitHub automation (CLA bot, stale bot, labeler), release banner upkeep across major versions, and OpenSearch version bumps.
In-memory mocking library for AWS services used by tens of thousands of Python projects to test code that talks to boto3. Contributions added ACM and ACM PCA certificate lifecycle APIs, SES and WAFv2 coverage, and new implementations for Organizations, RAM, and Textract SNS integration.
