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.

About section background

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.

β€œLocal-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.
