1. OpenAI API Integration: By connecting to OpenAI’s natural language processing (NLP) engine, Proposals AI analyzes user-submitted job descriptions and returns a customized proposal, tailored to the job’s specifics.
2. User Experience (UX): A simple, intuitive user interface was designed to ensure freelancers could easily input job descriptions and generate proposals without technical knowledge.
3. Payment System (Stripe API Integration): Stripe was chosen for its secure and scalable payment processing capabilities. Freelancers can purchase proposal credits via Stripe, allowing for smooth and trusted transactions. Integrating the Stripe API involved configuring secure payment methods and handling billing features for different pricing tiers.
4. Security and Performance: The application incorporated measures to ensure data privacy and security, especially with payment data. The use of hashed passwords and secure database management was paramount in protecting user information.
