Moving past chatbots: deterministic, schema-validated AI agents with LangGraph and MCP
Why RAG chatbots stall in production, and how to build deterministic, schema-validated AI agents on AWS with LangGraph state machines and MCP.
Author
Cloud & Data Architect, AI/ML Engineer
He has delivered solutions across AWS, GCP, Hetzner, and bare-metal EU infrastructure, with a strong focus on scalable architecture, distributed data processing, and production-grade cloud systems. His work spans infrastructure-as-code with Terraform, serverless and containerized platforms, Spark and Hadoop-based data processing, data workflows, model integration, RAG systems, and AI-powered applications.
Oleks Saloid turns broad goals like "we need a unified data platform" or "we want to use AI in production" into working systems: secure cloud environments, scalable data pipelines, workflow orchestration, APIs, observability, deployment automation, and practical AI architectures that can survive real-world use.
On the journal he writes about moving AI and data platforms beyond the pilot stage: cloud solution architecture, big data engineering, MLOps, AI agents, RAG, EU-sovereign infrastructure, data quality in production, and the operational discipline that separates a promising prototype from a system that runs reliably without you in the room.
