I will build a python AWS lambda API with fastapi
About this Gig
Need a clean, reliable serverless API on AWS?
I will build a Python REST API using FastAPI and AWS Lambda, with clean code, database integration, validation, error handling, and automated unit tests.
I can work with:
- AWS Lambda and API Gateway
- Python and FastAPI
- DynamoDB
- Aurora, RDS, PostgreSQL and MySQL
- Boto3 and other AWS services
- Pydantic validation
- Pytest unit tests
- CloudWatch logging
You will receive maintainable source code, automated tests, and clear setup documentation.
This Gig is ideal for small backend APIs, MVP features, microservices, webhooks, internal services, and serverless integrations.
Complex AWS networking, existing infrastructure migrations, authentication systems, or larger APIs may require a custom offer.
Please message me before ordering if your project uses private VPC resources, complex Aurora/RDS networking, or requires changes to existing AWS infrastructure.

FAQ
What databases can you integrate?
I can integrate DynamoDB, Aurora/RDS, PostgreSQL, MySQL, and similar databases. Please contact me first for databases requiring custom networking or infrastructure.
Do you deploy the API to AWS?
AWS deployment is included in the Standard and Premium packages. It can also be added to the Basic package as an extra.
Do you provide unit tests?
Yes. All packages include automated unit tests using pytest.
Can you work with an existing project?
Yes. I can add endpoints or integrations to an existing Python/FastAPI codebase. Please contact me first so I can confirm the scope.
Can you connect the Lambda to other AWS services?
Yes. Integrations with services such as S3, SQS, SNS, EventBridge, Secrets Manager, and others are available depending on the project scope.
Do you configure Aurora or RDS networking?
Simple database integration is supported. VPC configuration, RDS Proxy, security groups, private networking, or larger infrastructure changes may require a custom offer.
Do I need to provide AWS credentials?
Only when AWS deployment is included. Never provide root account credentials. Access should be limited to the permissions required for the project and can be revoked after delivery.
Are AWS usage charges included?
No. Any AWS infrastructure or usage charges are paid directly through your own AWS account.
