服务
如何与客户合作
小团队实践：范围、交付与交接直接与我沟通。较重里程碑时可能搭档另一位工程师 — 同一路线图，无轮换团队。
Embedded & firmware
Firmware, embedded Linux, sensors, and interfaces - practical engineering for reliable systems.
CAD & mechanical design
Solid modeling, CAD workflows, and practical design for prototypes and small-scale production.
Managed hosting
Deployment through fully managed operations - pick the tier that matches how hands-on you want to be, across common hosting models.
3D models
Browse interactive 3D previews. Custom parametric modeling is scoped separately.
3D scanning
Structured-light and photogrammetry workflows to bring physical parts into CAD and simulation.
CFD
Flow and thermal sketches for ducts, enclosures, and components - scoped to actionable design feedback.
FEA
Static and modal sketches for brackets, spools, and load-bearing parts - tied to material and manufacturing choices.
3D printing
FDM and resin printing scoped to material, tolerance, and finish requirements.
如何与客户合作
数据导向的设计
解决问题不止于一次发布。我看完整产品生命周期 — 不仅是上线，还有长期可维护性与体验。不做忽视上线后后果的赶工。
「本地优先」式解法
规模恰到好处：长期软件往往扩展现有资产比租用他人栈更划算。您的软件、硬件与约束 — 不强制全盘替换。
动手型工程
直接协作：清晰沟通、诚实权衡、交付到交接全程负责 — 无轮换团队或不透明流程。
