I am Carl Zeng, I’ve spent 22 years building business software for organizations in NetSuite system. Now I am continue working in the related tech industry, available for time-billable base off-site works.
With more than ten years of hands‑on SuiteScript development experience, I maintains own reusable code library. My expertise covers business‑process optimization and third‑party system integrations, including RESTlet‑based data synchronization between WMS/TMS and NetSuite. Projects are billed by working hours, with complete online documentation covering requirements, development and testing. Full source code and technical deliverables are handed over to clients. I takes a pragmatic delivery‑first approach, minimizing heavy business overheads to resolve real‑world NetSuite digital‑transformation pain‑points for enterprises, and has received written testimonials from past clients for warehouse, inventory‑related, transportation management related customization work(WMS, TMS, ERP).

How it works
I keep the process straightforward. No surprise scopes, no mystery timelines.
1. Tell me what you’re trying to solve
Describe the problem, the opportunity, or the gap — whether it’s NetSuite system, a consulting engagement, or a custom software project.
2. I scope it and give you a straight answer
I’ll tell you honestly whether I can help, what the approach would look like, and what it would take. No commitments until we’re both clear.
3. I design and build it
I handle the design, development, and delivery. You stay informed throughout, but you don’t need to manage the technical work.
4. You go live
You get a production-ready solution, documentation, and support through launch. No handoff into a void.
