Where the work concentrates.
ERP and operational systems
Custom ERP covering orders, purchasing, inventory, warehouses, accounting and reporting, shaped around how the operation actually works.
EDI, marketplace and logistics integration
ANSI X12 EDI inside the ERP, Amazon Vendor Central and SP-API, Walmart, Shopify and eBay, multi-warehouse inventory and live carrier rate shopping.
Legacy modernization
Extending long-running ASP.NET and commercial systems in place, including years of continuous ASP Classic to ASP.NET migration on live production systems.
SaaS architecture
Multi-tenant platforms with tenant isolation, subscription billing and background automation, including taking over and extending products already in production.

ENGINEERING APPROACH 01 02 03 04
How decisions get made.
Understand the operation first
Architecture decisions follow the workflow, the data and the exceptions people deal with, not a template.
Extend before replacing
Where an existing system still holds working business logic, the responsible option is often a modern layer around it.
Build integrations inside the system
EDI, marketplace and carrier connections belong where the orders and inventory live, so failures can be traced and fixed.
Stay accountable after launch
Most of the systems above are still being extended and supported, which keeps design decisions honest.
