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。
Our services
CAD, embedded, and web - built for real systems
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.
How I work
Owner-led engineering, end to end
You work directly with me - no account team and no bait-and-switch bench. I scope web, firmware, and mechanical work with clear milestones, demos, and docs your team can maintain after handoff.

Who you work with
Engineering across web, firmware, and hardware
These layouts are demos, but the intent matches how I work: clear ownership, tight feedback loops, and deliverables you can ship - not slideware. Reach out through the real contact routes on this site when you are ready to talk scope.
