cmiVFX · cmiUniverse

Case study

Modernize the marketplace behind a training business.

The situation. cmiVFX’s training business brought together visual effects instructors, their content, and paying learners. Its marketplace needed to support subscriptions, payments, and instructor revenue sharing.

My contribution. Through Mackley Studios, I rebuilt the global profit-sharing training marketplace and modernized subscription and payment services. I worked with the instructors producing content and built administration tools for videos, pricing, chapters, project files, and revenue shares.

What the work enabled. The rebuilt marketplace and administration tools supported the training catalog and its commercial workflows. Related cmiUniverse work included a tutorial player and browser-based creative tools, shown in the project gallery below.

How this relates to your product. When your business depends on an existing platform, I can work through its customer experience and operational systems together, including the payments and administration behind the screen.

cmiUniverse: creative tools in the browser

The challenge. Bring project management and specialized video and 3D tools into a web-based workspace for visual effects production.

My contribution. Built playback scrubbers, custom resizable windows, particle-effect generators, advanced color pickers, and theme designers. The work also included video encoding scripts, watermarking, and privacy and security tools.

The result. Brought specialized creative tools into the browser, with real-time synchronization across tabs and mobile devices so the workspace could stay connected across screens.

Naples Florida Vacation Homes

Case study

Connect a booking page to the work behind a reservation.

The situation. Vacation-rental booking needs more than a property page. Availability, date selection, pricing, and payment must fit the business’s existing rental workflow.

My contribution. I built booking tools for Naples Florida Vacation Homes and customized its calendar and payment workflows, including integration with the Barefoot rental booking and payment system.

What the work enabled. The implemented booking interface brought availability, dates, pricing, and payment into the reservation workflow. The archived screenshot below shows the customer-facing booking tools.

How this relates to your product. If your customer-facing app needs to work with an established business system, I can assess the integration and build the interface and supporting workflow around it.

Grow.com · Epicor

Technical Lead

Full Stack Web & Mobile Software Engineer

Technical lead on Grow’s mobile business intelligence application, working within Grow’s engineering teams across the app and the services behind it. Also helped design a revamped web architecture for enterprise customers.

Selected projects

Case study

Bring the mobile app closer to the web experience.

The situation. Grow’s mobile business intelligence application needed improvements and repairs to bring it closer to the web experience. Customers using their phones still needed access to their business data.

My contribution. I worked on the mobile application and across frontend, backend, and DevOps to connect it with Grow’s distributed systems. My work included live data updates, alongside support for Epicor integration and a revamped web architecture.

What the work enabled. The work brought live data updates and improvements to the mobile experience. This was a contribution within Grow’s engineering teams, spanning the app and the services it depended on.

How this relates to your product. When an app behaves differently across devices, I can investigate the interface, data flow, and supporting services together, then work through the changes with your team.
