Experience

• Hardware & PCB Design Brady Corporation · Full-time Jun 2022 – Present 4 yrs 2 mos Pittsburgh, PA, United States Hardware Architect - MECCO / Brady Corp. - R&D Core Technology June 2022 - Present
  - Own schematic-level architecture, PCB constraints, validation planning, and production handoff for industrial marking controller
  platforms from concept through manufacturing and sustaining support.
  - Recovered embedded controller performance by auditing DDR layout, timing constraints, reset topology, power sequencing, clock
  routing, and critical interfaces; helped reduce programming and test failures from roughly 33% to 1 in 2,000+ produced units.
  - Architected next-generation dual-FPGA and SoC safety controller platform with isolated industrial I/O, deterministic FPGA safety logic,
  embedded two-axis motion control, diagnostics, field-upgrade support, and UI/IoT reporting.
  - Defined schematic architecture, PCB layout constraints, firmware documentation, software ICDs, and validation plans for a 1,000+
  component board with 3,000+ connections, 10+ voltage domains, 1.5 kV isolation, automated FPGA verification test benches, and
  about 20% BOM cost reduction.
  - Re-architected constrained embedded controller from a stacked plug-in module approach to a flattened single-board design, reducing
  projected development timeline from over one year to under six months while adding fault monitoring, LCD, and touchscreen interface
  capability.
  - Developed FPGA motion architecture replacing costly MDrive hardware with backward-compatible MCODE ASCII processing and
  Trinamic TMC4361A/TMC2660C SPI control, reducing motion hardware cost from about $600 to about $100 per axis.
  - Directed Dot Peen controller strategy and custom eight-layer baseboard architecture using Efinix FPGA, LMC33 module socket, USB-
  to-SPI programming, Ethernet/IP, RS232, opto-isolated I/O, LVDS motion interfaces, controlled impedance, and quick-turn prototype
  manufacturing.
  - Improved embedded software release governance by implementing CI/CD validation gates, release binary control, and PLM/ECO
  approval workflow to reduce risk of unvalidated production releases.
  - Supported V&V, reliability, and manufacturing readiness work including thermal validation, safety logic validation, power cabling
  review, interlock behavior, vendor hardware workaround validation, OrCAD library standardization, component substitutions,
  cable/harness builds, and LMC33 tester recovery.
• Systems Engineer Siemens · Full-time May 2018 – Jun 2022 4 yrs 1 mos Pittsburgh, PA, United States Systems Engineer - Siemens Mobility - Onboard Systems January 2020 - June 2022
  - Designed embedded railway hardware integrations and six power supply designs meeting EN 50121 EMC and environmental
  requirements.
  - Created automated universal test fixture and test procedures supporting hardware/software integration, validation, production
  troubleshooting, and field upgrade work.
  - Managed requirements, subsystem design reviews, production issues, wiring harnesses, lifecycle troubleshooting, and rugged
  onboard system integration.
  - Created portable axle generator test fixture using BLDC motor design knowledge and worked with cross-functional teams to resolve
  integration and production issues.
  Engineering Development Program - Siemens Mobility - R&D / Onboard Systems January 2018 - January 2020
  - Designed FPGA-based BLDC motor control system and hardware test automation for gate mechanism lifecycle validation,
  contributing to six patent filings.
  - Designed configuration power supply board and supported manufacturing, field integration, active speed sensor integration, and
  technician-led system upgrades.
