Fifteen years of electrical engineering across industrial automation, aerospace avionics, RF telecommunications, and electric mobility have given me a rare end-to-end perspective — from first principles on a whiteboard to hardware shipped at scale.

I began my career at Siemens Industrial Drives, designing three-phase motor control hardware and power conversion stages. A move to Airbus brought me into avionics PCB design under DO-254 DAL-B, followed by six years at Nokia Bell Labs working on mmWave antenna array front-ends and phased array radar. Most recently, I led electrical architecture for the powertrain ECU at a Series C e-motorcycle startup.

"I believe that rigorous simulation and careful layout should make first-spin hardware work — not luck. I've achieved that on 34 of my last 35 board spins."

I hold seven patents across GaN power conversion, phased array beam-steering, and ultra-low-power IoT radio architectures. I'm an active IEE member and occasional IEEE TPEL reviewer.

DESIGN PROCESS

// Methodology
01
System Architecture
Define electrical requirements, select power topology, draw block diagrams, establish power budgets and thermal envelopes. Identify worst-case and fault conditions. Choose semiconductors and magnetics for first-pass sizing.
02
Schematic & SPICE Sim
Full schematic capture with parametric SPICE models. Simulate across line, load, temperature, and component tolerance corners. Validate control loop stability (Bode plots, phase margin). No layout starts until simulation is solid.
03
PCB Layout & SI/PI Review
Stackup selection, controlled impedance routing, thermal via arrays, high-current plane pours, and PDN impedance simulation. Signal integrity analysis for all high-speed interfaces. Mandatory peer review before Gerber release.
04
Bring-Up, Test & DFM
Structured hardware bring-up procedure: power sequencing, quiescent checks, functional validation, and characterisation across temperature. EMC pre-compliance testing with CDN and LISN. DFM optimisation before production handoff.

CLIENT FEEDBACK

// Testimonials
"

Dmitri's GaN converter design hit our efficiency target of 97% on the very first prototype spin. That's extraordinary. His simulation discipline is unlike anything I've seen in 20 years of hardware development.

KM
Klaus Müller
CTO · Thunderbolt eMobility
"

His phased array antenna front-end work was instrumental in our 5G NR base station winning the Verizon C-band contract. Dmitri's RF knowledge at mmWave frequencies is genuinely world-class.

AL
Aino Leinonen
Research Director · Nokia Bell Labs
"

We had a notoriously difficult EMC failure on a flight control board. Dmitri identified the root cause in two days of bench work that had stumped our team for three months. His systematic approach is remarkable.
