Field notes
Field notes on legacy modernization, code knowledge graphs, AI context, and the hidden system intelligence inside critical software.

Why AI Struggles With Legacy Codebases
AI coding tools can help modernize legacy systems, but only after the codebase has been turned into a structured, queryable map.

The Knowledge Cliff: What Happens When Your COBOL Experts Retire
When legacy experts retire, companies lose more than programming skill. They lose the operating knowledge hidden inside critical systems.
- March 2026
A Private Equity Guide to Technical Diligence on Legacy Software
PE firms inherit more than product and revenue. They inherit architecture, hidden technical debt, and modernization risk.
- February 2026
Modernizing Patient Portals Without Breaking Critical Workflows
Healthcare portals sit on top of fragile workflows, sensitive data, and old integrations. Modernization has to start with a system map.
- January 2026
What Is a Code Knowledge Graph?
A code knowledge graph turns files, functions, workflows, business rules, and dependencies into queryable system intelligence.

MCP for Legacy Systems: Giving AI Agents Safe Access to System Context
MCP gives AI agents controlled access to structured legacy system context, so they can work from a verified map instead of raw files.
- November 2025
The Hidden Cost of “Just Rewrite It”
Rewrites fail when teams underestimate hidden business logic, integrations, and dependencies. Modernization should start with a map.
- October 2025
How to Find Business Rules Hidden Inside Legacy Code
Business rules often live inside legacy conditionals, jobs, integrations, and exceptions. Recovering them is essential before modernization.
- September 2025
Security Discovery in Old Codebases: What AI Alone Misses
Old systems hide security risk in relationships: auth paths, data flows, privileged jobs, dependencies, and integrations.

From Codebase to Executive Briefing: Translating Technical Debt Into Decisions
Executives need more than vague technical debt warnings. They need codebase complexity translated into risk, sequencing, and investment decisions.
