Industries we serve

Nine years of plant-floor work across electronics, food processing, packaging, medical devices, metal fabrication and intralogistics — mostly within a two-hour drive of Milpitas.

Where we work

Rooted in the Bay Area, comfortable travelling

Our base at 643 Dundee Ave in Milpitas puts us inside an hour of most of Silicon Valley's manufacturing corridor: Fremont, San Jose, Hayward, Livermore and Gilroy. We regularly travel to the Central Valley and Salinas Valley for seasonal processing work, and take on projects in Nevada, Oregon and Arizona where the scope justifies the travel.

Because the owner previously ran commissioning teams in São Paulo, we also support US companies operating Brazilian plants — drawings, training material and operator screens delivered in both English and Portuguese.

  • Local: Milpitas, San Jose, Fremont, Hayward, Livermore, Santa Clara
  • Regional: Sacramento, Stockton, Salinas, Central Valley
  • Remote-first support available anywhere in the continental US

Sector experience

Six sectors, one engineering discipline

The physics changes; the method does not. Instrument first, quantify the loss, fix the constraint, document the result.

Contract electronics & semiconductor support

SMT lines, conformal coating, burn-in racks and test cells. Traceability down to the panel serial and clean handoffs between placement, reflow and AOI.

  • Serial-level traceability and label verification
  • AOI and ICT result capture into a single quality record
  • Cleanroom-compatible panel and cable practice
  • Tool-to-MES messaging for fab support equipment

Food, beverage & agricultural processing

Wash-down environments, allergen changeovers and audit trails that survive a customer inspection. Much of our Salinas Valley work is seasonal-capacity driven.

  • Recipe management with signed changeover records
  • CIP sequence logic and verification
  • Metal detection and checkweigher reject accountability
  • Temperature and dwell logging for HACCP evidence

Packaging & converting

Cartoners, case packers, palletisers and print-and-apply. Usually the fastest place to win back minutes, because accumulation is rarely tuned.

  • Accumulation and buffer logic tuning
  • Fast changeover recipes with tool-less setpoints
  • Label and barcode verification loops
  • Palletiser pattern management

Medical device & life sciences

Validated environments where the documentation is the deliverable. We work inside your change-control process, not around it.

  • IQ/OQ documentation support and traceability matrices
  • Audit trails and electronic-record considerations
  • Change control aligned to your QMS
  • Calibration and verification scheduling

Metal fabrication & general industrial

Press lines, welding cells, CNC load/unload and finishing. Frequently a safety-first conversation before productivity.

  • Guarding, light-curtain and interlock redesign
  • Robot load/unload cells for existing machines
  • Die-change and tool-tracking logic
  • Energy monitoring on high-draw equipment

Warehousing & intralogistics

Sortation, AS/RS interfaces and AMR traffic handoffs where the WMS and the conveyor controls need to agree.

  • Conveyor zone control and merge logic
  • Barcode / RFID read-rate improvement
  • WMS-to-PLC interface design
  • Throughput modelling before capital spend
