If your IBM i (AS400) or Mainframe system runs mission‑critical operations, you need modernization without risk I help organizations stabilize, modernize, and integrate legacy IBM i / Mainframe applications while preserving uptime, performance, and business logic. My approach focuses on incremental, low‑risk modernization—extending system life while enabling web, API, cloud, and AI‑driven innovation. With deep hands‑on experience across RPG, COBOL, Mainframe technologies, EDI integrations, and modern web stacks, I provide senior‑level ownership from assessment through production support. What I Bring IBM i / AS400: IBM i (AS400), iSeries, IBM Power Systems (V5R3–V7R5) — system modernization, application migration, performance optimization, and production stability. RPG & ILE: RPG Free, RPGLE, SQLRPGLE, RPG II–IV, CLLE, ILE — legacy refactoring, modularization, DB2 optimization, DDS‑to‑SQL migration. COBOL & Mainframe: COBOL, NetCOBOL, Fujitsu COBOL, CICS, JCL, DB2, VSAM — mainframe modernization, batch migration, performance tuning, controlled legacy transformation. Integration & Modernization: AS400 green‑screen to web (Profound UI, LANSA, SYNON, Rocket Aldon), APIs, EDI (ANSI X12, EDIFACT), ERP & Manhattan WMS integration, ESB, JSON, hybrid/cloud modernization, Angular & React frontends.
