Vintage hi-fi & audio
Turntables, cassette decks, receivers and amplifiers: cleaned, re-capped where needed, aligned and channel-tested. The kind of work that brings a dead deck back instead of landfilling it.
Electronics & computer repair
Diagnostics, board-level fixes, recovery and refurb on computers and consumer electronics. Diagnosis first, a quote before any work, no surprises on the invoice.
Ship it in or drop it off (Frankford, Philadelphia). How repairs work →
The same automated bench, as a service: bulk hardware testing with per-serial reports, bulk imaging and provisioning (Windows or Linux), custom golden images, and NIST 800-88 aligned data wipes: for resellers, schools, and offices with a pallet of machines, not one. See fleet services →
The day job behind the bench: I build AI-powered software for small businesses instead of another SaaS subscription, plus platform and DevOps work when that's the actual need. Separate from the shop, same person. See the consulting work →
