IBM i • RPG • Modernization
I modernize IBM i systems with web frontends, mobile scanning, and real-time integrations — without ripping out what already works.
What I Do
Your IBM i runs your business. I make it easier to use, faster to operate, and ready for what's next.
Replace green screens with responsive web interfaces that talk directly to your DB2 data. Your team gets a modern UI — your RPG programs keep running.
Barcode and QR code scanning from any phone or tablet. Real-time inventory updates, bilingual interfaces, and no more clipboards in the warehouse.
Connect your AS/400 to the tools your team already uses — APIs, dashboards, reporting platforms. Your IBM i data, accessible everywhere it needs to be.
Normalized DB2 schemas, SQLRPGLE programs, and data structures built for performance. Clean architecture that scales with your operation.
Purpose-built warehouse management running natively on IBM i. Pallet tracking, location management, and inventory workflows designed for cold storage and distribution.
New RPGLE and SQLRPGLE programs, maintenance of existing codebases, and migration from legacy fixed-format RPG to modern free-format.
Streamline invoicing, reporting, and bookkeeping workflows tied to your IBM i data. Automated reconciliation, Excel report generation, and integrations between your ERP and accounting systems — less manual entry, fewer errors.
Recent Work
Production systems handling real inventory at scale — not classroom exercises.
Full-stack warehouse management app running on IBM i. 11 normalized DB2 tables, SQLRPGLE backend programs, REST APIs via Node.js/Express, and a responsive web frontend — replacing manual tracking across 17,600+ pallet locations.
Phone-based scanning workflow replacing handwritten pallet location tracking in freezer warehouse environments. QR code label generation, real-time inventory updates, and English/Spanish interface for the full warehouse team.
Hands-on production access to IBM i systems managing 17,600+ pallet locations in cold storage. DDS display files, CL programs, and RPGLE development deployed directly into live operational environments.
About
I'm Jaden — an Operations & Inventory Analyst who learned IBM i by solving real problems in a cold storage warehouse, not in a classroom.
When our warehouse needed better pallet tracking, I didn't wait for a consultant. I learned RPG, built the database, wrote the programs, and deployed to production. When the team needed to ditch clipboards, I built mobile scanning.
Most IBM i developers are retiring. I'm just getting started. I combine deep warehouse operations knowledge with modern development skills to build solutions that actually get used by the people on the floor.
Based in Southern California. Available for remote and on-site work.
