My Technical Approach
AI Application Architecture
I design AI applications with a focus on modularity, scalability, and maintainability. My approach separates AI model serving from business logic, enabling independent scaling and easier updates to AI components.
GraphQL API Design for AI
I follow a schema-first development approach for AI-powered APIs, ensuring clear type definitions that model the business domain accurately. My resolvers are optimized to prevent N+1 query problems and handle AI model responses efficiently.
Frontend Architecture
Component-driven development with clear separation of concerns between smart and presentational components. I implement efficient state management patterns for handling AI-generated content and real-time updates.
LLM Integration Strategy
I implement a layered approach to LLM integration, with abstraction layers that separate prompt engineering, context management, and response handling. This enables easier switching between models and fine-tuning for specific use cases.
Case Study: AI-Powered Content Generation Platform
Challenge
