Architect solutions using agentic frameworks, integrating with vector databases and advanced memory architectures
Build APIs, data pipelines, and enterprise integrations (CRM, ERP, cloud platforms)
Evaluate and refine AI performance using LLM-based evaluation, agent metrics, and A/B testing
Ensure performance, security, observability, and cost-efficiency across deployed solutions
Conduct research, rapid prototyping, and experimentation to validate feasibility and business value
Stay current with emerging AI protocols (MCP, A2A, ACP) and evolving LLM technologies
Requirements
