About Me

David Krcek

Over 30 years in IT, a good chunk of that in the SAP world. By day, enterprise architecture and SAP systems at consolut; by night, SwiftUI development, Obsidian vaults, local language models, and open source.

This blog is my personal notebook — not a company site, no sponsored content. I write about whatever currently keeps me busy: artificial intelligence beyond the cloud, Apple Silicon as a developer platform, SwiftUI experiments, open-source projects like BookBridge, and occasionally a bit of attitude (#fckafd).

Focus Areas

• SAP & Enterprise — SAP Basis, HANA, Cloud Provisioning, system landscapes
• AI & Local Models — MLX, Ollama, Qwen, MCP servers, Claude Code
