Convert Node.js API to TypeScript AWS Lambda

Description

We are looking for a skilled developer to enhance our API backend by converting existing JavaScript code, currently built with Node.js, Express, and MongoDB, into TypeScript for AWS Lambda. The new implementation should leverage ES6 features and must not include Express. Additionally, the project will require integrating AWS services such as SNS (for SMS) and SES (for email) for authentication, authorization, and verification.
Responsibilities:
1. Code Conversion: - Convert the existing JavaScript API code to TypeScript for AWS Lambda, ensuring all functionality is retained while enhancing the code with ES6 features.
2. AWS Integration: - Integrate AWS SNS for sending SMS notifications. - Integrate AWS SES for sending email notifications.
3. Authentication & Authorization: - Implement authentication and authorization processes using AWS services. - Develop verification workflows for email and SMS.
4. MongoDB Integration: - Ensure seamless integration with MongoDB for data storage and retrieval.
5. Error Handling: - Identify and fix any potential errors in the existing codebase. - Implement robust error handling in the new TypeScript code.
6. Serverless Framework: - Develop and deploy the application using Serverless Framework version 4.
Requirements:
- Strong expertise in TypeScript and Node.js.- Familiarity with AWS services, specifically SNS and SES.- Experience with MongoDB and serverless architectures.- Proficiency in ES6 features and the Serverless Framework.- Ability to write clean, maintainable, and well-documented backend code.
Deliverables:
- A fully functional TypeScript API codebase deployed on AWS Lambda without Express.- Integrated AWS SNS and SES for SMS and email notifications.- Documentation outlining the setup, usage, and any relevant information for future maintenance.
If you are interested in this project, please provide examples of your previous work with TypeScript, AWS, and MongoDB. Include your estimated timeline and budget for completion.
Looking forward to your proposals!
