About me
Working at the intersection of mechanical design, embedded systems, and the web, that mix shows up in my projects: from CAD and hardware bring-up to shipping usable software and interfaces people actually enjoy.
This site is my home base on the internet, writing, projects, and ways to work together. If you want the full story, see the resume, blog, LinkedIn, or Instagram (@jheffmedia).
Based around Philadelphia. Available for remote work with cloud-first delivery, async collaboration, and crisp written updates. On-site is by appointment only.
Services
How I work with clients
Small practice: you work directly with me on scope, delivery, and handoff. For heavier milestones I sometimes pair with one other engineer—same roadmap, no rotating cast.
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.
How I work with clients
Data-oriented design
Problem solving goes beyond shipping once. I look at the full product lifecycle—not just launch, but long-term maintainability and customer experience. No rush jobs that ignore what happens after release.
“Local-first” problem solving
Right-sized solutions: for durable software, it is often cheaper to extend what you already own than to rent someone else’s stack. Your software, your hardware, your constraints—no forced rip-and-replace.
Hands-on engineering
Direct collaboration: you get clear communication, honest tradeoffs, and ownership through delivery and handoff—not a rotating cast or opaque process.
Let's talk
Tell me what you're building, your timeline, and what success looks like. I'll follow up with questions, a proposed scope, or a quick call. Whichever fits.
