Serious Talent,
Fun People

Fusionbox is a 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


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.

Molly Sum

Project Manager

I have always been drawn to puzzles, and when I found myself in the world of project management, I was excited to be surrounded by opportunities to employ creative problem solving and organizational techniques that I’d perfected through years of personal and academic use. My time as an Agile Project Manager has allowed me to contribute meaningfully to a variety of project scales, and I sincerely enjoy the time I spend creating and executing project plans. To support our clients, I am also an Agile Certified Practitioner, Professional Scrum Master, SAFe PO/PM, and ICAgile Certified Professional in Team Facilitation and Agile Coaching.

Justin Stollsteimer

Sr. Designer

I’ve always been a nerd for design. I get as much joy out of comparing football teams’ logos as I do actually watching the games (Go Broncos). While I officially studied Computer Science, I had always sought a way to combine the methodical science of software engineering with the creative, artistic outlet of graphic design. As our industry has grown, I’ve found the most successful designs came from user-focused research, starting with an empathic understanding of both the customer and the client.

Gavin Wahl

Sr. Software Engineer, Director of Security

As a senior software engineer, I participate in the entire process of building an application, including the formulation of proposals and quotes, discovery and analysis of client requirements, implementation, and deployment. I also act as a mentor and technical lead for the rest of the programming team. As Director of Security, I oversee security practices, policies, and training at Fusionbox. I’ve placed in the top 20 in global security competitions, given security talks to Fortune 100 financial institutions, and written Open Source security software.

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. As a mobile application developer these days, I love building efficient, reliable software. However, I am still most driven by creating experiences that surprise and delight by being extra thoughtful, intuitive, and fun.

Alex Bliskovsky

Sr. Software Engineer

I have been building software for about half my life, and professionally for almost a decade. I have been involved in all aspects of building software, from initial planning, to legacy maintenance. I have been heavily involved in Fusionbox’s security policies and internal practices. Outside of work, I like to spend my summers building trails with Volunteers for Outdoor Colorado, a group that is funded by one of our clients, the Colorado Lottery.

Clint Dunn

Sr. Software Engineer

I started programming while I was in school for mechanical engineering. I learned that developing software was something that I had a knack for and was very interested in pursuing. Following that interest led me to pursue a master’s degree that focused on computational modeling. Throughout my time in graduate school I freelanced as a Python software developer. Since then I have been developing websites with Django. In every project I not only find a new and exciting technical challenge, but I also strive to put myself in the client’s shoes, and create a product that we can both be proud of.

Will Burroughs

Product Designer

I gravitated toward design via my love of problem solving and passion for storytelling. As a product designer, I work at the nexus of user experience, client vision, and business goals. I craft designs that integrate user needs into the broader product vision and allow for the creation of engaging and intuitive products while prioritizing authentic communication, deep understanding, and collaborative problem-solving.

Brian Perrett

Software Engineer

I've always been passionate about problem solving and puzzles. I initially thought this passion would lead me to work in physics but as I neared the end of my 4th year of college, I became more and more unsure about what opportunities to pursue after graduation. After receiving my B.S. in physics, I worked at an e-commerce company, tasked with building and maintaining an order/inventory management web app. It was a difficult but fulfilling task. Since then, I’ve spent much of my free time learning about technologies surrounding the web and working on my own hobby projects along the way.

Courtney Spratford

Jr. Software Engineer

As a nature lover and environmental conservationist, a natural start to my career was in environmental cleanup. I started my career in environmental consulting and remediation, managing various sized clean-up projects and conducting soil and groundwater sampling events. I learned software development on the side as a hobby, constantly building and discovering new technologies in my spare time. One day I decided to take the plunge and become a professional software developer because I truly enjoy learning and problem solving.

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.
