Engineering across web, firmware, and hardware
Owner-led consulting for teams that need clear scope, working prototypes, and documentation that survives handoff - not slideware or a fake bench.

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.

What I can help with
Web & product engineering
From prototypes to production: TypeScript, Astro, APIs, and reliable delivery for your product and team.
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.
What people are saying
"Solid scoping, steady demos, and documentation we could actually hand off. No bait-and-switch on stack or timeline."
Geoffrey
Product lead
"Firmware and web moved together - fewer integration surprises than we are used to on hardware projects."
Connor D
CTO, startup
"Clear tradeoffs, no mystery months. We always knew what was in scope and what was next."
BowTiedFocus
Founder
"Practical CI and test discipline without boiling the ocean. Good fit for a small team."
Aniket P
Engineering manager
"Mechanical and software constraints were discussed in the same room - saved us rework."
David G
Hardware lead
"Responsive, pragmatic, and allergic to unnecessary process. Exactly what we needed."
