System integration that connects your business
Most business environments rely on multiple systems exchanging data across operations, finance, warehousing, retail, and reporting. I help organizations connect those systems reliably — through practical, supportable data flow.
What ERP Connects
Finance & Accounting
Accounts payable, accounts receivable, general ledger, budgeting, and financial reporting.
Warehouse & Distribution
Inventory management, receiving, shipping, logistics, warehouse operations, and handheld scanner integration.
Purchasing & Supply Chain
Procurement, vendor management, purchase orders, and supply chain planning.
Sales & Customer Management
Customer accounts, order management, pricing, CRM, and sales pipeline.
Retail & Point of Sale
Store operations, transactions, merchandising, pricing, promotions, and POS item file synchronization with host systems.
Human Resources
Payroll, scheduling, benefits, hiring, compliance, and workforce management.
Manufacturing & Production
Production planning, work orders, quality management, and bill of materials.
Reporting & Business Intelligence
Dashboards, analytics, operational metrics, and data-driven decision support.

How Integration Work Differs from Point Solutions
A strong networking and communications background — including IP, synchronous and asynchronous protocols, and low-level data exchange — supports my integration work at every layer. This is not just API calling. It includes understanding how data moves at the protocol level, diagnosing problems that span multiple systems, and designing interfaces that handle failures gracefully.
That same discipline carries into network and security infrastructure. I have built API-driven configuration and custom operational reporting against enterprise firewall platforms like Fortinet, including work alongside Fortinet Professional Services on mass deployment automation. Network and security automation is the same integration craft applied to a different class of infrastructure, and it fits naturally inside broader integration and custom development engagements.
I have built integrations between IBM i systems, Linux-based platforms, Windows applications, cloud services, and external trading partners. The systems change; the discipline of reliable data exchange does not.

Mainframe & IBM i Data Integration
I build integrations that bridge mainframe and IBM i systems with modern platforms. This includes creating and consuming interface files in EBCDIC, packed decimal, and fixed-width formats, transforming COBOL copybook layouts into relational structures, and building ETL pipelines that handle the encoding and format conversion these environments require.
