CHARAN PETA

I’m a GenAI Full Stack Developer with 2YoE, focused on building multi-agent workflows, RAG systems, and scalable AI applications. I take ownership of backend architecture and turn AI ideas into production-ready platforms.

At Sonata Software, I led backend engineering for AgentBridge, an AI workflow orchestration platform. I architected the GraphEngine on LangGraph for dynamic node execution, context propagation, parallel tasks, retry logic, streaming responses, and full workflow state management.

I also designed A2A (Agent-to-Agent) server lifecycle and orchestrated secure runtime communication between agents. On the enterprise side, I implemented OAuth2.0 integration (e.g., Jira/Salesforce actions) and automated AWS infrastructure with Terraform and OIDC-based authentication between GitLab and AWS.

I build systems end-to-end—from retrieval and evaluation to deployment—using RAGAS-based evaluation to measure context relevance, correctness, faithfulness, and response completeness. My work includes agentic travel planning, an AI support bot for password resets with Lex/Connect, and RFP response generation grounded in enterprise knowledge.
