HelloLeo: Advanced AI Agent Platform

The Challenge

Modern AI development requires sophisticated orchestration of multiple language models, seamless integration with various platforms, and intelligent context management. Developers need a unified platform that can:

• Orchestrate multiple LLM providers efficiently

• Implement advanced retrieval-augmented generation (RAG)

• Integrate with popular platforms like Contentful, Supabase, and Klaviyo

• Handle complex agentic workflows with self-reflection capabilities

Our Solution

We developed HelloLeo, an enterprise-grade AI agent platform that demonstrates our mastery in modern AI engineering:

Core AI Capabilities

• Multi-LLM Orchestration - Seamless integration with OpenAI, Claude, Groq, Fireworks, Gemini, OpenRouter, and Ollama

• Retrieval-Augmented Generation (RAG) - Powered by Qdrant vector database with semantic code search capabilities

• Agent Architecture - Multi-agent system with specialized agents for Git operations, coding, RAG queries, and workspace management

• Model Context Protocol (MCP) - Custom and third-party integrations including Xano, Supabase, Airtable, Contentful, and Klaviyo

Advanced AI Techniques

• Custom Tool Creation using FastMCP for extensible agent capabilities

• Self-Reflection Loop with critic agent for auto-correction and quality assurance

• Dynamic Prompt Engineering leveraging Jinja2 templating system for flexible prompt generation

• Context Management with chat history and conversation state tracking

• Streaming Responses for real-time token streaming and enhanced user experience

Technical Excellence

• Agentic Code Generation with Aider integration for intelligent code editing

• Git-Aware AI with automated commits and AI-generated commit messages

• Multi-Modal Context combining code structure, documentation, and repository analysis

• Type-Safe Operations using Result monads for robust error handling

• WebSocket Real-Time Communication for async AI streaming to clients

Frameworks & Tools

We leveraged industry-leading frameworks including LangChain for LLM orchestration, Aider for AI pair programming, FastMCP for MCP server development, and Pydantic for schema validation.
