Example engagements showing problem, solution, and measurable outcomes.
Problem
Prototype boards booted intermittently and failed under relay switching transients in field-like conditions.
Solution
Power sequencing analysis, decoupling redesign, and firmware startup order changes with oscilloscope-guided validation.
Outcome
Stable boots across temperature range and 0 bring-up failures across the next 30 units.
“Clear debug process and practical fixes we could productionize quickly.”
Problem
Node battery life was ~3 weeks, below target of 3 months.
Solution
Current profiling, rail-domain gating strategy, duty-cycle optimization, and low-leakage BOM replacements.
Outcome
Measured runtime increased to 14+ weeks on the same cell chemistry.
“The redesign paid for itself in one pilot batch.”
Problem
Pre-scan failed in two bands due to converter harmonics and cable emissions.
Solution
Layout return-path corrections, filter retuning, and harness/common-mode mitigation before formal testing.
Outcome
Pre-scan margins improved enough to proceed confidently to certification test booking.
“Fast, targeted changes with measurable EMC impact.”
