Set Up a Consultation

Fusionbox is a Python software development agency in Denver, Colorado. We've helped companies develop secure, well-architected software since 2002.

We are a small team of talented Python Engineers and UX designers. To say Fusionbox is a builder of software is certainly true, but it’s a small part of the story. Within our code is a unique approach to business:

  • Hire people obsessed with problem-solving
  • Be human to tune in to our clients’ challenges
  • Use technology as a means to solve problems
  • Be the best at that

We've helped organizations large and small not only writing code, but developing their vision for how to get there. Our clients include the Colorado Lottery, FirstBank, Delta Dental, Boston Mutual Insurance and Citywide Banks.

Meet Our Team


Ivy Hastings

CEO

I’ve been involved in building software since 1998 when I worked on a multi-million dollar project during the first Internet boom. Despite that project going bust, I stuck with it. My favorite thing about what I do is getting to know the people behind the software. This means having empathy and understanding for both client and end user needs. I excel at big picture thinking, so while the rest of the team is executing, I’m thinking about how the project will solve the client’s goals, including how the end product will further business objectives. My experience with branding, marketing, and entrepreneurship helps me understand what makes projects successful.

Will Burroughs

Product Lead

With more than five years of experience designing and building products, my expertise lies in harmonizing intuitive product design with strategic business objectives and customer needs. As a Product Manager with a background in UX Design and Frontend Development, I delve deeply into user research, product strategy, and experience design. This unique blend of skills enables me to empower our team to craft products that are not only intuitive but also technically feasible and aligned with our clients' business goals. My strength is in guiding projects from concept to launch, ensuring every facet of the product contributes to a comprehensive and effective experience. I am committed to developing solutions that solve real problems, driving growth, and enhancing customer satisfaction by leveraging my technical and design expertise.

Justin Stollsteimer

Sr. Designer

After completing my studies in Computer Science in the early ages of the web app industry, I sought a way to combine the methodical science of software engineering with visual design, and voila—a UX designer was born lo those 20 years ago.

I’ve found the most successful designs came from user-focused research, starting with an empathic understanding of both the customer and the client. I’ve helped our clients translate user data into meaningful next steps, replace antiquated pencil-and-paper processes, and create engaging digital experiences. Give me a messy problem and I’ll work with you to create an elegant solution that looks great, too.

Gavin Wahl

Sr. Software Engineer, Director of Security

As a senior software engineer and Director of Security at Fusionbox, I orchestrate the entire lifecycle of application development while ensuring robust security practices. With a track record of placing in the top 20 in global security competitions and delivering talks to Fortune 100 financial institutions, I bring a wealth of expertise to the table. Beyond my technical roles, I also serve as a mentor and technical lead, guiding the programming team to success. What began as a hobby in my basement has blossomed into a fulfilling career where I tackle complex problems with creativity and logic, relishing in projects that require difficult software engineering to challenge the status quo and lack simple solutions. Technologies I like to work with are Python, Typescript, and PostgreSQL.

Nolan Stover

Sr. Software Engineer, Mobile Development

I started my career as a designer and animator, making experimental multimedia websites and games in the pre-mobile-browser days. As standards evolved, so did my understanding of the web and my enthusiasm for all its underlying technologies. I embraced Django early as a way to get familiar with these technologies without misapplying them. Now, whether I'm building a traditional HTML site, a ReSTful API, or a data-driven React Native application for Android and iOS, Django is still at its core, providing me the structures to clearly express myself using Python and SQL. As I'm programming, I'm still driven by what I was in the beginning, creating thoughtful, intuitive experiences that have the capacity to surprise and delight.

Brian Perrett

Sr. Software Engineer

I have been programming professionally for almost a decade now. It simultaneously feels like an eternity and no time at all. I have largely spent that time building web applications using some combination of Python, Django, and React with Typescript. Having used these technologies for many years I've gotten a good grasp on what works and when, and have spent ample time weighing the pros and cons of using different stacks. I've come to prefer the conciseness of Django and its "included batteries", but am happy to reach to a frontend framework like React or one of its various flavors if a project's complexity necessitates it. I always enjoy discussing new problem spaces with clients and brainstorming solutions.

Brian Gaudino

Sr. Software Engineer

With several years of professional experience building web apps with Django and React, I am equally comfortable on both the backend and the frontend. Though I have worked with many languages and frameworks, I am drawn to Django because it is mature, secure, and battle-tested. I'm always excited to learn new technologies and lately I've been incorporating AI in applications in creative ways.

Before pivoting into software development, I had a decade-long career as a musician and educator. I'm drawn to programming for some of the same reasons I appreciate music: creativity, problem-solving, and continuous learning.

Python Community


We are committed to giving back to the python community through our support of Django Girls & Meetup events and our yearly sponsorships of PyCon & DjangoCon. In addition, our team contributes academically via lectures on Python and Django as well as their contributions to the Django core.
