Our Process

1

Requirements Analysis

Understanding business logic and technical requirements

  • Analyze functional and non-functional requirements
  • Define API endpoints and data models
  • Identify third-party services and integrations
  • Plan database schema and relationships
  • Establish performance and scalability requirements
2

API Design & Documentation

Designing RESTful APIs with clear documentation

  • Design API endpoints following REST principles
  • Define request/response schemas and data structures
  • Document APIs using OpenAPI/Swagger specifications
  • Establish versioning strategy for APIs
  • Create API documentation for frontend team
3

Database Design

Designing efficient database schema and relationships

  • Design normalized database schema
  • Define table relationships and constraints
  • Plan indexing strategy for query optimization
  • Set up database migrations and version control
  • Implement database seeding for development
4

Implementation & Development

Building API endpoints and business logic

  • Implement authentication and authorization middleware
  • Build CRUD operations for data entities
  • Create business logic and validation rules

Code Quality

At least two team members have reviewed and approved the code changes

Code follows team coding standards, style guide, and best practices

ESLint/Prettier passes with zero errors and warnings

Complex logic is well-documented with clear comments and JSDoc

All console.log statements and debug code removed from production

Testing

Minimum 80% code coverage with meaningful unit tests

All integration tests pass successfully in CI/CD pipeline

Feature tested manually across different scenarios and edge cases

Verified functionality in Chrome, Firefox, Safari, and Edge
