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

Impact
#

  • 50%+ reduction in manual document processing time
  • Production-grade reliability with <1% error rate on agent tasks
  • Scalable architecture handling thousands of daily agent interactions
  • Knowledge democratization — internal knowledge accessible via natural language
