# Challenges Faced

The primary challenge was designing the architecture of a two-sided freelance marketplace where multiple interconnected workflows had to work together consistently. The platform required carefully structured relationships between users, professional profiles, skills, jobs, applications, contracts, payments, and reviews. Another significant challenge was implementing a reliable hiring lifecycle from job discovery and application submission through selection, contract management, and payment processing. Integrating AI-powered matching, Redis-based temporary data handling, Google OAuth, and Stripe while maintaining a clean and scalable application architecture added further complexity.
