Selected engineering work

Systems that have to keep working.

A selection of production work across software architecture, payment and peripheral integration, applied AI, and industrial controls. Some implementation details are intentionally limited to respect proprietary systems.

012023—Now

Store Systems Architecture

Architecture · Production software

Architected a major restructuring of AutoZone’s store-side software ecosystem, reducing duplicated logic and creating clearer boundaries between applications, shared services, and physical hardware.

02Production

Receipt Platform

C++ · Hardware abstraction

Redesigned receipt printing around a centralized, printer-agnostic abstraction, replacing hardware-specific implementations and making support for current and future printer models simpler.

03Production

Peripheral Modernization

USB/Serial · Embedded systems

Delivered long-running USB printer and cash-drawer modernization work while engineering backward-compatible support across roughly forty years of serial and USB store hardware.

04Production

Payment Integration

Payments · Compliance · Security

Led specialized integration and certification work to bring payment terminals into compliance and production, with device responsibilities performed directly by the retailer.

05Ongoing

Applied AI Systems

Model training · Evaluation · Integration

Trained and evaluated open-weight models, contributed engineering-domain expertise to model development, and helped integrate AI capabilities into constrained enterprise workflows.

062021—2022

Industrial Controls

PLC/HMI · Commissioning · Industrial networking

Designed and implemented PLC, HMI, industrial networking, and electrical-control solutions for manufacturing environments. Coordinated technicians, vendors, contractors, and plant personnel through installation, commissioning, troubleshooting, and safety requirements—including restoration and modernization following major facility damage.

072020

Facility Electrical Systems

Electrical design · AutoCAD · Revit

Designed electrical, security, fire-alarm, and control systems for correctional and government facilities using AutoCAD and Revit, translating operational and security requirements into technical designs and field installations.

Engineering notes

A closer look at the problem solving.

Public summaries of representative work, focused on the engineering decisions rather than proprietary implementation details.

AStore systems

Keeping new hardware compatible with decades of infrastructure

Challenge: Modern USB peripherals needed to operate alongside legacy serial equipment without forcing stores into a disruptive, all-at-once hardware replacement.
Approach: Separated device behavior from application logic, centralized the hardware boundary, and preserved the established communication paths required by older equipment.
Outcome: Created a practical migration path where modern and legacy devices can coexist while future integrations become easier to test, support, and replace.

BControls engineering

Restoring control systems after major facility damage

Challenge: A manufacturing environment needed electrical controls, PLC logic, HMIs, and industrial networking restored and modernized under real operational and safety constraints.
Approach: Worked across design, programming, installation, commissioning, and troubleshooting while coordinating plant personnel, contractors, technicians, and vendors.
Outcome: Helped move the work from damaged infrastructure and technical drawings toward a commissioned system that operators could safely use and maintain.

CTransaction integrity

Hardening returns and imported-cart processing

Challenge: Inconsistent tax, price, rate, and refund data between stores could create incorrect or difficult-to-explain totals—and expose financial-loss scenarios.
Approach: Traced transaction behavior across system boundaries, identified where assumptions diverged, and strengthened validation around the affected flows.
Outcome: Made transaction results more consistent and explainable while reducing the opportunities for accidental loss and deliberate abuse.
