Key Activities:

 Frontend Development: Create responsive interfaces

(React, Angular).
 Backend Development: Set up servers, databases
(MySQL, MongoDB), and APIs.
 Third-Party Integrations: Payment processors, analytics
(Google Analytics), and marketing tools.
 Security Measures: SSL encryption, fraud detection, and
secure authentication (OAuth).
Deliverables:
 Functional e-commerce platform, code repositories, test
cases.

E-commerce Example: Developing a Shopify app for

personalized discounts or integrating a chatbot for customer
support.

4. Testing & Quality Assurance (QA)

Objective: Ensure the system is bug-free, secure, and performs

optimally.
Key Activities:

 Functional Testing: Check checkout flows, search

functionality, and user accounts.
 BCOS – 184
