Your extension strategy will fail certification if you hook into undocumented MOCA events that Manhattan deprecates in the next release. I've seen three WMS upgrades stall because custom RF screens bypassed the standard SCI layer and broke when Manhattan refactored their session handling. Quick questions - are you targeting WMOS or Manhattan Active, and do you have existing custom tables that need migration into the new extension schema? Here is the architectural approach: - MOCA FRAMEWORK: Build all workflows as standalone MOCA commands with explicit input/output contracts so Manhattan's upgrade validator can parse dependencies without false positives. - INTEGRATION FRAMEWORK: Use MIF adapters with versioned XML schemas for inbound/outbound messages, ensuring backward compatibility when Manhattan patches their core integration engine. - REGRESSION TESTING: Automate test execution through your CI pipeline using Manhattan's command-line test harness, capturing baseline snapshots before each sprint so QA can diff results against known-good states. I've delivered four production extensions for WMOS clients in 3PL and retail distribution that survived two major version upgrades without rework. Let's schedule a 20-minute technical review to confirm your current Manhattan version and extension boundaries before we lock the sprint plan.

You need to optimize an existing Windows terminal ZIP utility so it keeps the exact CLI workflow and archive output while cutting real compression time in milliseconds. I have 9+ years of production experience with C/C++, C#, debugging, software architecture and performance optimization. I’ll profile the current implementation first using your sample archives, measuring CPU, I/O, memory allocation, threading and checksum overhead before changing the compression path. Then I’ll apply only optimizations that produce a measurable gain, such as parallel processing, SIMD/hardware acceleration, a faster compression implementation or targeted low-level changes. I’ll preserve archive compatibility and verify byte-for-byte output against the current version. You’ll receive the optimized Windows build, source changes, reproducible before/after benchmarks and build/run notes. One point I’d confirm first: what does “EIP” specifically refer to in your current code or requirements?

The key here is keeping every extension outside Manhattan’s core objects — so future WMOS/Active upgrades don’t turn custom workflows into a maintenance problem. I’d structure the work around the MOCA extension points first, then build the RF screens and integration adapters as isolated custom components. For each sprint, I’d keep the changes reviewable in Git and document the hooks, tables, configuration, and deployment steps as they’re introduced. For the technical side, I can work across Java, MOCA scripting, SCI reporting, and integration-layer development, with unit/regression coverage around the custom logic and a clean promotion package for QA. One thing I’d confirm before starting: are you extending Manhattan WMOS or Manhattan Active, and which version/release is currently running in the sandbox? If you can share one representative workflow/spec, I can outline exactly where I’d hook into MOCA and how I’d keep it upgrade-safe. Available to start with the first sprint and review it with your team.

Adding new workflows and RF screens on top of MOCA without touching core objects can be fragile when Manhattan upgrades change internal tables. I'll isolate the custom code in separate MOCA scripts and use the Integration Framework adapters to keep the core untouched. All changes will live in the shared Git sandbox and be packaged with the standard promotion path for easy deployment. A common mistake is hard-coding table names in MOCA hooks, which breaks as soon as a patch adds a new column. I always read the spec, then add a layer of abstraction that pulls table names from the configuration so upgrades stay safe. You can expect a clean compile, zero failed tests, and clear documentation that shows every hook and table change.

When you layer new MOCA extensions on top of existing workflows, hidden table name collisions can break future upgrades. I'll isolate each custom table with a unique prefix and add a version check hook that aborts if the core schema changes. This keeps the core objects untouched while letting the new RF screens and adapters run safely. A common pitfall is relying on static SCI reports that stop working after a patch changes field IDs. I’ll generate the adapters using the Integration Framework's dynamic mapping so the code adapts to schema shifts. Ready to start immediately and push the first feature to your shared Git repo.

Hi, Manhattan extension work tends to go wrong in the same quiet way: something gets hung off a core object because the sandbox allowed it, and the next Manhattan release breaks it during a promotion nobody budgeted time for. Straight answer first, because it's more use to you than a pitch. Deep MOCA scripting and SCI reporting inside WMOS or Active isn't our ground, and pretending otherwise would cost you a sprint finding out. What we do build is the layer around a WMS: web-facing screens, dashboards and adapters that read from the warehouse system and hand work to people, hand-coded so there's no plugin stack to break. If any part of this scope is that rather than core MOCA extension work, it's worth separating out before you award. A few quick questions: 1. Are the RF screens native Manhattan RF, or browser-based on handhelds? 2. Does anything in this scope face customers or suppliers outside the warehouse?
