FAQ
What do I need to get started?
Once you place an order (or before, during discussion), please provide a brief overview of your project, AWS account access (IAM user or temporary credentials), and details about any services you want integrated (API Gateway, S3, SES, etc.). I’ll guide you through the rest.
Can you build a complete backend using AWS Lambda and API Gateway?
Yes! I can build a fully functional backend using Lambda and API Gateway, whether it’s RESTful APIs, background jobs, or event-driven workflows. It will be scalable, secure, and production-ready.
Will you configure environment variables and secrets securely?
Yes, I use AWS Systems Manager Parameter Store (SSM) or AWS Secrets Manager to securely manage your environment variables and secrets.
Can you integrate third-party APIs or external services?
Definitely! I can integrate your Lambda functions with third-party APIs (e.g., Stripe, Twilio, external webhooks) as long as their usage fits within AWS Lambda’s runtime constraints.
Do you provide post-delivery support?
Yes, I offer basic post-delivery support to help you test and verify the deployment. If needed, we can also discuss extended support as a custom offer.
Is my AWS access safe with you?
100%. I take data privacy and account security very seriously. Access is only used for the duration of the project and strictly for agreed-upon tasks.
