About Michael
Enterprise modernization, architecture, AI-assisted engineering, and visual creativity.
Michael presents deep technical material in a way that gives first-time visitors a clear path while preserving the evidence, architecture notes, and machine-readable context technical reviewers may need.
.NET and SQL modernization
Stabilizing legacy ASP.NET, C#, SQL Server, stored-procedure, reporting, and line-of-business systems before replacing or restructuring them.
Typed front ends and API contracts
Using TypeScript, Angular, RxJS, browser-local tools, and explicit API contracts to make complex systems easier to review and evolve.
AI-assisted engineering with review
Designing prompt contracts, semantic-search workflows, structured documentation, handoff memory, and review checkpoints without treating AI output as self-validating.
Architecture and technical mentoring
Translating undocumented business rules into maintainable services, tests, comparison evidence, and reviewer-readable architecture.
How Michael works
Behavior first, evidence visible, architecture maintainable.
- Preserve business-critical behavior before attempting broad rewrites.
- Use comparison screens, characterization fixtures, and automated tests to make parity visible.
- Keep source evidence, assumptions, generated material, and human judgment distinguishable.
- Prefer explicit contracts, small service boundaries, and maintainable systems over hidden coupling.
- Treat AI as an engineering aid that still requires human review, correction, and accountability.
Creative and public interests
Technical systems are only part of the picture.
- Photography, visual composition, and public media archiving.
- Information architecture and AI-readable documentation.
- Source-governed long-term memory, file handoff, and knowledge-system design.
- Accessible interfaces that serve both first-time visitors and technical reviewers.
