About Michael

Software architecture, modernization, and reviewable AI-assisted engineering

Michael Kappel is a senior software engineer and software architect with more than twenty years of enterprise delivery experience. His public work emphasizes preserving business-critical behavior while modernizing long-lived software and data systems.

.NET and SQL modernization

C#, ASP.NET and ASP.NET Core, Web API, Razor Pages, SQL Server, T-SQL, stored procedures, reporting, service seams, and behavior-parity validation.

TypeScript and Angular

Typed front-end patterns, Angular and RxJS, accessible interfaces, API contracts, browser-local tools, and maintainable component architecture.

Human-reviewed AI workflows

Prompt contracts, semantic search, durable memory, file and project handoff, evidence labels, review checkpoints, and explicit boundaries that keep people responsible for final decisions.

Architecture and evidence

Legacy-system stabilization, business-rule translation, regression testing, source-aware documentation, machine-readable review files, and technical case studies that explain how conclusions were reached.

Photography and visual creativity

A separate creative practice focused on photography, composition, public media archives, and visual systems.

Public-interest publishing

Research-oriented sites and documentation that make technical systems, evidence boundaries, long-term memory, and public records easier for people and software agents to inspect.
