The most amazing...

...system I designed, built, and coded is for blood pressure control for critically ill patients. It was tested successfully in the Royal Melbourne Hospital ICU.

Work Experience

Founder, Product Developer

2019 - PRESENT
SJC Engineering
  • Designed a system for servo controllers. The system is Atmega328p-based and controls up to 128 servos. I developed C++ libraries and main routines, including self-test diagnostics and the user interface.
  • Designed, manufactured, and debugged prototype circuit boards.
  • Completed successful acceptance testing with the client.

Founder, CEO

2014 - 2021
ClearEvent Inc
  • Founded ClearEvent with partners in Ontario and San Francisco. ClearEvent is a full-service event logistics and collaboration platform.
  • Drove feature development based on customer demand, developed features and decomposed them into stories, and led backlog triage and grooming to focus work on the most valuable features.
  • Developed extensive Excel tools for business modeling and real-time analytics, which enabled me to efficiently drive business strategy, sales, marketing, product development, customer success, and investor relations.
  • Drove development of the company website and marketing materials.

SaaS Event Management Platform

A web-based platform used by event management professionals to create, promote, manage, and monetize events such as conferences, trades shows, and exhibitions. I led the development of this system, which has been in commercial operation since 2015 and has thousands of users and millions in processed revenues.

Blood Pressure Controller

A dedicated, x86-based clinical hardware system for closed-loop control of blood pressure in critically ill patients. Blood pressure is measured, and the infusion rate of a vaso-active agent is adjusted by the system using PID control with continuous assessment of patient sensitivity. The system provides continuous blood pressure control, thereby freeing critical care staff to deliver higher-quality medical care. I designed, built, and coded this system.

Patient Simulator

A C++ model of a critical-care patient, simulating variations in key medical indicators, such as heart rate, respiration, blood pressure, temperature, and oxygen saturation. The patient simulator enabled debugging and testing of a clinical system under development for blood pressure control.

DNA and RNA Array Spotter Control System

A control system and database for an X-Y-Z liquid dispensing robot configured to create DNA and RNA arrays on microscope slides. The system processed input tray maps (raw DNA solutions) and array configuration maps (desired output) to create up to 64 spotted arrays for experimental use.

DNA Fragment Assembly for Array Sequencing

A software-based system for alignment and reassembly of 500 to 1,000 DNA sequences into an optimal aggregate sequence. The system was prototyped in Perl and rewritten into C++. Testing required the generation of many test sequence sets, both optimal (solvable) and non-optimal (not solvable without gaps in the sequence).

Microprocessor Interlocking Controller

A microprocessor-based system for controlling railroad interlocking plants. The system self-discovers the network topology from a list of plant components and a connection list. Routes are indicated by selecting start and end points. Candidate routes are determined via optimized search methods based on connections and occupancy.

User Configurable Control Panel

A C++-based system for user creation of control panels for sequential actuator control. The system is based on self-discovering, microcontroller-equipped tiles capable of learning their neighbors and deducing the corresponding network topology.
