Ethan G.

7 years at Intel as an Electronics Design Engineer, now independent — every Upwork project rated 5.0. Tier-1 semiconductor companies bring me in for overflow PCB layout; for startups, I'm the expert they can't hire full-time. I'm the engineer to call when a board is too complex, too fast, or too power-hungry to get wrong on the first spin — or when you need measurements you can actually trust. Not the cheapest bid; the one who gets it right. To date, each board I've designed has come up working the first time. "Within minutes it was obvious he understood the problem at a level I hadn't encountered before — he was already asking questions our own team hadn't thought to ask. They found several issues that would have been a nightmare to deal with after the fact ... the board went to manufacturer on time, and I actually felt good about it. What I appreciated most was that Ethan just owned it — the same attention to detail that caught those issues carried through the entire engagement." — Daniel L., Founder, VC-backed hardware startup · February 2026 Need one engineer to own your whole board, concept to debugged hardware? Or extra senior hands on an overflow layout? Either way, you get the same silicon-grade rigor. Through my firm, EGS Engineering, I cover the full range of electronics and PCB design — a broad base of everyday board work, with deep specialization in two areas: ▸ HIGH-COMPLEXITY COMPUTE PLATFORMS — high-speed, high-power, high-density boards for datacenter and AI hardware (CPUs, ASICs, SoCs, FPGAs), power delivery into the hundreds of amps, and silicon validation. ▸ PRECISION MEASUREMENT & TELEMETRY — trustworthy measurement chains from nanovolts to volts, modeled, calibrated, and lab-validated. ──────────────────────────────────── SPECIALTY 1 — HIGH-COMPLEXITY COMPUTE PLATFORMS The hardest class of digital hardware: high-speed, high-power, high-layer-count, high-density boards with thousands of components. • Full-board ownership around CPUs, ASICs, SoCs, FPGAs, and MCUs — architecture, schematic, layout, and bring-up • High-speed interfaces under real signal-integrity constraints: PCIe Gen4, DDR3L, LPDDR5, DRAM, ONFI/NAND, eMMC/SD, USB, HDMI, I2C, SPI, I3C, and custom buses • Up to 24-layer stackups owned end to end — signal integrity, power integrity, and DFM/DFA locked before release, so you don't burn a fab cycle and weeks of schedule on a respin. • Power Electronics — multiphase VRMs up to 12 phases and 360 A, and the board/package PDN around them, kept within spec at hundreds of amps: model extraction, PDN/PI simulation, regulator tuning, and validation against target-impedance and transient budgets. • SSD validation platforms exposing the controller, NAND/Optane media, rails, and PCIe — custom sockets, breakout/pathfinding, instrumentation, bring-up, debug, and firmware support. ──────────────────────────────────── SPECIALTY 2 — PRECISION MEASUREMENT & TELEMETRY Measurement you can stake a design decision on. I don't just drop in an ADC and hope for the best. I architect the entire measurement chain, model it, extract and ingest models, and design the calibration and validation so the numbers on the screen actually mean something. • Architected and led teams to build TWO mixed-signal measurement platforms (precision analog front ends + FPGAs) delivering accurate power and temperature telemetry for storage and memory devices • Front ends spanning nanovolts to volts and milliamps to hundreds of amps — architected, modeled, and lab-correlated so the reading is one you can defend in a design review, not one you have to take on faith. • Precision AFEs (INA / op-amp), ADCs, voltage references; temperature sensing via thermistors, RTDs, and BJTs; TEC control • Modeling and validation: SPICE, MATLAB/Simulink, Python — model extraction, lab correlation, Bode, load-step, calibration ──────────────────────────────────── Start small if you want to: send me your specs or invite me to your job and I'll give you an honest read on scope, risk, and whether I'm the right fit — that first conversation is on me. Need a deeper answer before you commit? I also offer paid scoping consultations — a written risk and architecture assessment you can act on. Either way, you'll know exactly where you stand before any real work begins.
