- Design fallback and error-handling mechanisms for AI services
- Optimize inference performance, latency, and API costs
- Implement authentication, authorization, rate limiting, and usage controls for AI endpoints
- Store AI usage and model activity in PostgreSQL
- Work with blockchain engineers to connect AI licensing and usage with smart contracts
- Build monitoring and logging for AI integrations
- Write integration tests and technical documentation

Requirements
- Professional experience integrating AI APIs or machine-learning services
- Strong Python and/or TypeScript experience
- Experience building REST APIs and backend services
- Experience integrating LLMs or generative AI
- Understanding of AI inference workflows
- Experience with React / Next.js is a plus

What You'll Help Build

The long-term vision is to make AI a core component of MarketHub:
AI Models → AI APIs → MarketHub → User Applications → GameFi/Web3 → Usage & Licensing
You'll help create the infrastructure that allows AI capabilities to become usable, measurable, and commercially integrated within the MarketHub ecosystem.
