What I bring
Enterprise software consulting across the full life of a business system.
My work has moved from hands-on application and database development into architecture, integrations, analytics, commerce platforms, operational systems and technical consulting. That breadth is useful when the real problem crosses several technical boundaries at once.
Legacy system modernization without losing business knowledge
Experience with Classic ASP, ASP.NET and long-running SQL Server platforms helps me modernize systems without ignoring the business rules already embedded in them.
Systems integration across APIs, SaaS and internal platforms
APIs, marketplaces, payment gateways, shipping carriers, SaaS platforms and internal applications are most valuable when they operate as one understandable business process.
Data engineering and analytics for operational decisions
Database engineering, ETL, reporting and analytics experience helps connect transactional systems to traceability, operational insight and management decision support.
Problems I help solve
The work usually starts with a business problem, not a technology request.
I am most useful when a system has grown complicated: old and new technology coexist, several platforms need to communicate, operational users need better tools, or the business needs a safer path from the current state to something better.
Operational workflowsBuild or extend internal applications around the real process.
Legacy modernizationImprove long-running systems without discarding valuable business knowledge.
Systems integrationConnect platforms, APIs and external services into one business workflow.
Commerce operationsModernize storefront and back-office processes across orders, returns, payments and fulfilment.
Data & analyticsTurn operational SQL data into useful visibility and decision support.
Security & paymentsEngineer payment workflows with infrastructure, access and compliance in view.
Breadth beyond the flagship case studies
A wider engineering background built over more than two decades.
The seven case studies are selected examples. My broader experience also spans databases, marketplaces, carrier integrations, payment platforms, reporting, legacy web systems and the operational plumbing behind eCommerce businesses.

How I approach architecture
Solution architecture starts with the business workflow, system boundaries and production risk.
I decide what should be reused, modernized, replaced or integrated by looking at users, business rules, data, dependencies and production risk—not by forcing every project into the same technical pattern.
