I build production AI agents that integrate with your existing systems: LangGraph agents with tool calling, RAG over your internal data, and AI automation wired into your database, CRM, APIs, and ticketing. 4,700+ hours building inside live client codebases, legacy schemas, rate-limited vendor APIs, inconsistent documents, compliance constraints. Demos are easy. Integration is the job. WHAT I BUILD AI operations agents. LangGraph agents that read and write to your production systems — PostgreSQL, internal REST APIs, CRMs, ticketing tools, S3 document stores, with tool calling, structured outputs, memory, and human approval gates on consequential actions. AI support and triage agents. Customer support automation combining RAG retrieval, live SQL lookup, intent classification, confidence thresholds, and human escalation. Every answer cites its source. Document AI and data extraction. Automated document processing with AWS Textract and Bedrock: OCR, structured extraction, custom schemas, validation logic, and human review queues for low-confidence records. Production RAG systems. Hybrid vector search with reranking, metadata filtering, and citations over internal documentation, databases, and support history, built on pgvector, Qdrant, or OpenSearch. PROBLEMS I SOLVE AI agent that connects to our CRM, database, and internal APIs Customer support agent that answers from our knowledge base and escalates correctly Automate manual document processing, invoice extraction, or data entry RAG chatbot over internal company documents with accurate citations LangChain or LangGraph prototype that needs to become a production system AI agent hallucinating, leaking data, or failing silently in production LLM costs or latency too high to scale PRODUCTION STANDARDS Every build ships with an eval set from your real cases, tracing via Langfuse or LangSmith, token and latency cost tracking, guardrails and output validation on anything customer-facing or writing to a system of record, and defined escalation paths. SELECTED WORK: FX liquidity agent, treasury desk. Autonomous agent across different telecomuunication channels: GPT-4o-mini OCR on text and image rate tables, policy validation, Kafka to PostgreSQL and a live React dashboard. Sub-2-second latency, 100% automated, zero manual entry. Agentic document intelligence, private investment platform. LangGraph agent on AWS Bedrock with multi-tenant RAG (OpenSearch) and natural-language-to- MongoDB querying, Bedrock Guardrails, Langfuse observability. Onboarding extraction from days to ~10 minutes. All acceptance criteria passed. GraphRAG fraud investigation, crypto compliance. Multi-exchange entity resolution into a Neo4j graph; GraphRAG agent converts plain English to Cypher for multi-hop wallet tracing. Selected for an FBI and DEA pilot. CORE STACK Agents and LLMs: LangGraph, LangChain, OpenAI, Claude, AWS Bedrock, tool calling, function calling, structured outputs, MCP Retrieval and RAG: pgvector, Qdrant, OpenSearch, hybrid search, reranking, citations, metadata filtering, chunking strategies Backend: Python, FastAPI, PostgreSQL, Redis, Celery, REST APIs, webhooks AWS: Lambda, Step Functions, ECS, Bedrock, Textract, S3, API Gateway, Terraform, Docker LLMOps: Langfuse, LangSmith, eval pipelines, output validation, cost tracking, latency optimization BEST FIT You have a real operational problem, existing systems the agent must integrate with, and it has to run in production, not a demo. Not a fit for prompt-only work, one-off scripts, or a chatbot with no integration behind it. Tell me what the agent needs to do and which systems it touches, and I will tell you honestly whether it is a two-week build or a two-month one.
