Expertise / The way I work
Deep in the details.
Clear on the whole.
I connect the operating problem to the data model, the application, and the people who will own it after launch.
01 / Capability
Data that can explain itself.
SQL Server is my center of gravity: a place to make business rules, provenance, and performance explicit.
- Relational modeling and maintainable T-SQL ETL
- Point-in-time financial reconstruction
- Metadata-driven contracts and incremental synchronization
- Query tuning, concurrency, and production diagnostics

02 / Capability
Change without losing the business.
Before replacing a system, understand the behavior people already depend on. Then build the evidence that the replacement is right.
- Undocumented-system discovery and dependency analysis
- Reversible migrations and identity cross-references
- Differential testing and source-to-target reconciliation
- Legacy application and document conversion

03 / Capability
Software shaped around the work.
I build operating systems for real teams: rules, permissions, workflows, and interfaces that can evolve without becoming disconnected.
- C# / .NET and database-driven application architecture
- Declarative UI and schema-generated contracts
- Approval, consent, and role-sensitive workflows
- Delivery ownership from discovery through support

04 / Capability
The space between systems.
The difficult part is rarely calling an API. It is preserving identity, intent, and recoverability when independent systems change.
- IRIS STAR and accounting-firm platform internals
- REST, SOAP, EDI, OAuth, and token lifecycle
- Exception routing and continue-from-failure processing
- Vendor boundaries, reusable transports, and audit trails

05 / Capability
AI with an accountable foundation.
My current research brings retrieval, provenance, independent verification, and relational observability into AI-assisted work.
- Retrieval and structured knowledge extraction
- Bi-temporal assertion ledgers and provenance graphs
- Evaluation harnesses that retain partial and unverifiable results
- C# lifecycle instrumentation and SQL Server agent telemetry
