About TopicTrick
Deep-dive tutorials on enterprise architecture, mainframe development, and AI engineering.
Who Writes TopicTrick?
TopicTrick is written by practising developers and architects with direct, hands-on experience in the technologies we cover. Our editorial focus is narrow and deliberate: we publish deep technical tutorials on three subjects where good, practitioner-written content is hard to find.
What We Cover
Enterprise Architecture: TOGAF & Zachman
Our TOGAF content is written with the certification exam in mind and the real-world practitioner in parallel. Every ADM phase guide includes the key outputs, exam facts, and practical notes on how phase activities work in real organisations — not just the official specification language.

Mainframe Development: COBOL, CICS, IMS, DB2 & HLASM
Our mainframe tutorials are written for developers entering or advancing in z/OS environments. All code examples use real z/OS syntax validated against current IBM documentation. We cover COBOL through to HLASM assembler, with full learning paths for CICS online transaction development and IMS hierarchical database programming.

AI Engineering: Claude API & Anthropic
Our Claude API tutorials are written for software developers building production AI applications. Content focuses on what official documentation does not cover: production patterns, cost optimisation, agent architecture, and real-world build projects with working code.
