MASHANG DELIVERY is a software delivery studio based in Hangzhou, serving clients remotely across China and abroad. We are not an agency and we do not subcontract. The studio assigns a fixed lead to each of the three roles — frontend, backend and operations — and core members come from first-tier internet platforms, with long records in building and running large-scale business systems, high-concurrency workloads, complex domain modelling and production stability work. The engineers who take your project are the ones who deliver it: requirements, design, implementation, deployment and acceptance are handled start to finish by the same team. Employment history is verifiable — see "The Team & Verifiable Track Record" for how. We also build and operate our own products: the Android app WuQuan, the WeChat Mini Program PaiQian, and online resume and ID-photo tools, all maintained by this team from first release through every iteration.

Senior engineers deliver the work, and their records check out
An in-house team with dedicated leads for frontend, backend and operations. The people you talk to are the people who write the code — nothing is passed along, and accountability is clear.
Backend Lead
8+ years in the fieldDomain modelling, API and data design, high-concurrency paths, third-party integrations
Led the batch filing rebuild for a listed tax SaaS and a marketing platform serving 200M+ private-domain users.
Frontend Lead
Page architecture and interaction, multi-platform adaptation, load performance and accessibility
Owns frontend delivery for websites, Mini Programs and apps — first-paint speed, compatibility and design fidelity.
Operations Lead
Servers and domains, deployment pipelines, certificates and backups, monitoring and alerting
The same engineer stays on after launch, so incidents have an owner and every change is recorded.
How the track record is verified
- Core members hold formal engineering roles at first-tier internet platforms; employer, tenure and position are verifiable.
- Just ask during the consultation: once an NDA is signed we share redacted employment and project records.
- We do not publish employer names or previous-employer project details publicly — that is a confidentiality obligation to former employers, not a sign the record cannot be checked.
Verification happens during the conversation and costs you nothing in decision time. If it does not check out, you are free to walk away.
和责任绑定的六条约定
You talk to the engineers
The person you speak with is the engineer writing your code. No sales layer, no subcontracting — delivery responsibility sits with a named person.
Track record you can check
Core members come from first-tier internet platforms. After an NDA is signed, we provide redacted employment and project records for you to verify.
Three roles, three fixed leads
Frontend, backend and operations each have a dedicated owner, so APIs, data, deployment and production stability are all somebody's job.
Code and accounts are yours
Full source code and usage documentation are handed over. Servers, domains and Mini Program accounts are all registered under your name.
Pay in stages
You see results before paying the next instalment. Projects above ¥5,000 are split into three stages (30% / 40% / 30%).
Supported after launch
Defects are fixed free for 30 days after launch, and an annual maintenance plan is available for long-term care.
