Summary
What's included
API Documentation
Detailed descriptions of the API endpoints, including methods (GET, POST, PUT, DELETE), expected request parameters, request body, and response format. Documentation on how security is implemented (e.g., OAuth, JWT), error codes, and sample usage examples.
Source Code
Complete codebase that handles the logic for business rules, database interactions, data validation, and security. The code should be stored in a version control system like Git, with proper branching strategies and commit messages. Testing frameworks should be implemented for unit, integration, and end-to-end tests, and Continuous Integration and Continuous Deployment configurations should be set up to automate the testing and deployment process.
Security Measures
Implementations for authentication and authorization (e.g., OAuth, JWT tokens, API keys), encryption for sensitive data both in transit (SSL/TLS) and at rest, and vulnerability assessments to address any known security risks.
Deployment Configurations
Configuration files for different environments (development, staging, production), containerization (e.g., Docker, Kubernetes), and cloud configurations for deploying to platforms like AWS, Azure, or Google Cloud.

Sheng was amazing — 10/10 recommend working with him. - Great communicator: I always knew where things stood, timelines, etc. - Talented web dev: I made a bunch of technical requests, he nailed them all. - High sense of ownership: He volunteered to clean up some of my UX/UI before we got started, just to make sure everything was looking great. - Super flexible: I made a few design changes late in the process and he rolled with it. TL;DR: Hire Sheng, you won't be sorry!
