Building an AI agent or RAG demo is easy. Making it reliable, secure, observable, and cost-predictable in production is where most projects fail. I design, build, and rescue production AI systems on AWS for SaaS and enterprise teams. Expert-Vetted (Top 1% on Upwork) | 100% Job Success | $80K+ earned 2,700+ hours | 41 jobs | 3x AWS Professional certified (Generative AI, Solutions Architect, DevOps) | 4x AWS Community Builder | 9+ years CLIENTS BRING ME IN WHEN - An AI agent works in a demo but breaks with real users, tools, permissions, retries, or live business data - A RAG system retrieves the wrong context or produces weak citations - AI inference and cloud spend swing unpredictably month to month - A proof of concept needs production architecture, security, and a safe deploy and rollback path - Claude, OpenAI, or Amazon Bedrock must connect to real workflows - An AWS platform has reliability, scaling, security, or cost problems WHAT I BUILD AI Agents and Agentic Workflows - Multi-agent systems with LangChain, LangGraph, tool calling, and MCP - State management, tracing, approvals, and human-in-the-loop escalation - Deterministic fallback paths for when the model is the wrong tool Enterprise RAG and Knowledge Systems - Hybrid retrieval (dense embeddings + BM25), reranking, and citations - Vector stores: OpenSearch, Pinecone, Qdrant, pgvector, FAISS - Tenant isolation and access control for multi-tenant data LLM Integration and Evaluation - Claude, OpenAI, Amazon Bedrock, and open-source models - Prompt engineering, guardrails, evals, and regression tracing - Cost and latency optimization for production inference AWS Platform and Serverless - Event-driven systems: Lambda, API Gateway, DynamoDB, SQS, EventBridge, Step Functions - ECS, EKS, RDS, OpenSearch, ElastiCache - Terraform, AWS CDK, CloudFormation, SAM - IAM least-privilege, observability, incident recovery, cost optimization TECHNICAL STACK Python, Node.js, TypeScript | LangChain, LangGraph, MCP | Claude, OpenAI, Amazon Bedrock | OpenSearch, Pinecone, Qdrant, pgvector | AWS Lambda, DynamoDB, Step Functions, EventBridge | Terraform, CDK, Docker, Kubernetes SELECTED PRODUCTION OUTCOMES - 43% reduction in monthly Lambda cost - 55% improvement in processing time - Event-driven ordering platform handling millions of transactions per month with strict uptime and recovery requirements - Production integrations across Claude, OpenAI, and Amazon Bedrock I AM A GOOD FIT IF - You want a system that survives real users, not another demo - You have real workflows, data, or a running product to build on - You want senior ownership and clear architectural decisions I AM NOT THE FIT IF - You are exploring AI with no use case yet - Price matters more than reliability and outcomes HOW I WORK I do not start with a framework. I start with your workflow, your data, your permission model, your failure modes, and your operating cost. That includes telling you when not to build something. I have advised clients against AI agents where a deterministic workflow was safer, against RAG where a direct query was enough, and against managed services that add cost or lock-in without earning it. Guardrails, evals, and tenant isolation reduce risk and improve reliability; they do not eliminate hallucinations, and I will not claim they do. Send me your architecture, repo context, or the production issue you are stuck on. I will identify the highest-risk path to production and the smallest safe step to fix it.
