    I help overwhelmed founders get their time back, their team on track, and their business running like a well-oiled machine. If you’re building something bold, beautiful, and meaningful — but feeling stuck in the daily chaos of decision fatigue, miscommunication, or duct-taped systems — I’m here for you. I created Out of Chaos Systems for founders like you: visionaries, creatives, and community-builders who didn’t set out to become operations experts… but still need things to run smoothly if your business is going to grow. As your Fractional COO/Operations Consultant, I bring structure, clarity, and real solutions — without slowing you down or burying you in jargon. WHAT I CAN DO FOR YOU I help you stop reinventing the wheel every time you hire, onboard, launch, or deliver. I build systems that fit your brain and your business, so things don’t fall apart when you get busy. I make your team way more effective, whether you’ve got two contractors or a full crew. I organize the chaos so you can get out of the weeds and back into your zone of genius. WHY TRUST ME? I’ve led startups through major growth — from messy beginnings to multimillion-dollar raises. I’ve built systems that make teams hum, founders breathe easier, and work actually get done. I specialize in working with queer, neurodivergent, and heart-led founders who value both purpose and performance. I won’t give you generic playbooks. I’ll co-create a system that works for you. You don’t need to “get better at ops.” You just need the right partner. Let’s build a business that supports your vision — and your nervous system.

    Civil engineering graduate with programming experience in C++ and Visual Basic for Applications, and quick to learn new tasks and programs. I have project experience with software quality assurance most notably from time spent while working under my professor on a program for the Rhode Island Department of Transportation to analyze roadway data and determine the most cost effective and beneficial treatment methods for damaged roadways. On this project I was responsible for creating the user interface as well as ensuring that algorithms and functions created by other group members worked properly with the data sets that the RIDOT would be using in practice.
