200OK Software Outsourcing Platform
Why this project exists
The problem
While taking software freelance jobs, I found that many general-purpose platforms were not built around software projects. They often missed the questions engineers needed answered, or asked them in ways clients could not understand, leaving both sides with unclear requirements.
The product idea
I wanted a platform designed around software outsourcing, where clients can post a project and engineers can respond with proposals, then clarify the work through direct conversation before moving forward.
How it works
- Client posts a project
- Engineer discovers it and submits a proposal
- Client reviews proposals
- Both sides discuss through messaging
- Contact information is unlocked to continue
Project Overview
200OK is a professional software outsourcing platform designed to connect clients with engineers, improving project collaboration quality and efficiency through transparent matching processes and AI-assisted mechanisms.
As a team member (Group 18), I contributed to the full-stack development of this platform, which supports complete workflows including project posting, proposal submission, real-time communication, and token-based payment systems.
Key responsibilities and features I worked on:
- Authentication & Authorization: Email registration with verification, Google OAuth integration via NextAuth.js
- Project Management: Full CRUD operations for project posting, browsing, and proposal management
- Real-time Communication: Socket.io integration for instant messaging between clients and engineers
- Token System: Digital token management for viewing proposals, submitting proposals, and unlocking contact information
- AI Integration: Google Gemini API integration for intelligent project matching and recommendations
The platform simulates real-world commercial platform operations with comprehensive business logic including payment flows, status machines, and automated refund mechanisms.
