KBC Bank & Insurance Leuven, Belgium 2023 - Present
Overview#
Building the bank’s first production AI agents — from architecture design to deployment and monitoring. Active participant in architecture design boards, driving technical decisions for enterprise-scale agentic systems.
Scale: One of Belgium’s largest banks with 12M+ customers
Key Achievements#
🤖 Production AI Agents#
- First internal AI agents deployed to production using AWS Bedrock and custom AgentCore framework
- Multi-agent orchestration for complex banking workflows (document processing, customer routing, compliance)
- Tool integration with internal banking APIs, document stores, and knowledge bases
- Memory management with session persistence and context windowing
🏗️ Architecture Leadership#
- Active participant in architecture design boards — driving technical decisions for AI infrastructure
- Designed event-driven agent pipelines using EventBridge, SQS, and Lambda
- Established guardrails and safety patterns using Bedrock Guardrails
- Built evaluation frameworks for continuous agent quality monitoring
📚 RAG Systems#
- Enterprise-scale Retrieval-Augmented Generation for internal knowledge management
- Hybrid search combining semantic embeddings with keyword matching
- Chunking strategies optimized for banking documents (contracts, policies, procedures)
- Incremental indexing for real-time updates to knowledge base
📊 AgentOps & Observability#
- Implemented agent tracing and trajectory evaluation for debugging complex agent behavior
- LLM-as-judge evaluation for response quality and hallucination detection
- Cost tracking and optimization for foundation model usage
- Latency monitoring and performance optimization
