Desktop Software Supports the Work That Matters
In the lab, in the airport hangar, or at the hospital bedside, the desktop is where critical work happens. We partner with teams who need dependable software–tools built for deep focus, detailed workflows, and decisions that can’t wait on a network connection. With decades of desktop experience, we help you build applications that perform reliably in environments where precision matters most.
Your Trusted Partner in Desktop App Development
Every organization has unique demands for their desktop tools—offline resilience, hardware integration, security boundaries, or workflows that power users rely on. We work alongside your teams to understand those needs and shape software that fits the way your people work. The result is a system that feels intuitive, reduces friction, and supports consistent, confident decision-making.
Custom Applications & Modernization
Purpose-built tools for real work.
We build and refresh desktop apps that keep pace with your teams and workflows.
Cross-Platform & Enterprise Connectivity
Work anywhere, connect to everything.
Your app runs everywhere and links smoothly to the data and services your people rely on.

How does SEP approach desktop development?
We use the same collaborative approach we bring to every SEP project—tailored for the reality of desktop systems, hardware needs, and the detailed workflows your teams depend on.
Discovery
We start by learning how your teams work today. That often includes mapping existing workflows, reviewing legacy code, exploring modernization paths, or testing ideas with quick prototypes. This helps uncover what will truly support your people—not just what’s technically possible.
Delivery
We create desktop applications that fit your environment, whether that means modernizing older .NET or Windows systems, building cross-platform tools with Qt or Electron, or integrating with hardware and enterprise systems. When low latency or security calls for it, we use edge-processing architecture and on-device AI to keep decisions fast and local.
Evolution
Desktop applications grow with the organizations that rely on them. We help you scale performance, expand to new platforms, support additional devices, and simplify complex areas of the product. The goal is a system your teams can trust—and continue to maintain with confidence.
We work alongside your people throughout the project, sharing what we learn and adjusting as needs shift. Desktop work is rarely linear, and that’s where a steady partner makes a difference.
Tools We Use to Build Desktop Systems That Last
We build desktop software with tools that match the lifespan and environment of your product. We build on frameworks with the future in mind – whether it’s a distributed app in .NET, an embedded GUI with Qt, or a cross-platform app with Electron – these apps need to stand the test of time and rise to the challenge of your power users.
.NET 
ASP.NET (Core, SignalR) 
C# 
Electron 
GTK 
MAUI 
Qt 
SwiftUI (macOS) 
WinForms (.NET) WPF/MAUI (.NET) When your work depends on physical equipment, high-performance, or security is paramount, we’ll build the right architecture to keep your processes running smoothly, and your users productive and secure.
Whatever the stack, our goal is the same: durable, dependable systems that help your teams do the work that matters.
Are these desktop challenges holding you back?
- “Is AI or on-device intelligence something we need, but don’t know how to approach safely?”
- “Is our legacy desktop app hard to change confidently?”
- “Do our workflows feel too complex for the tools we have today?”
- “Are we stuck with tech that won’t run on modern operating systems?”
- “Do our desktop apps need to work on Windows, Mac, and Linux—but don’t?”
- “Is it hard to connect our desktop tools with cloud services or internal systems?”
- “Do our users need offline reliability or low-latency performance we can’t achieve now?”
- “Are we struggling to integrate software with specialized hardware or lab equipment?”
We’ve seen challenges like these across industries—regulated, operational, and research-heavy alike. We can help you move past them.
Trusted by Teams Who Count on Their Products
“SEP felt like part of our team.”
SEP felt like part of our internal team—fully invested in the work and in our success. It was the most seamless experience I’ve had with any contract partner.
Desktop Work We’re Proud Of
Desktop Software Still Powers Work That Matters
Desktop software still powers some of the most important work in engineering, medical care, and manufacturing. These stories show how thoughtful design, modernization, and long-term collaboration help teams work faster, reduce errors, and make better decisions in the moments that matter. Each project reflects a simple goal: build desktop tools that support real people doing complex, daily work with confidence.
Modern Joist Design Software: Faster, Safer, Smarter
A rebuilt desktop app that cuts hours of engineering work down to minutes while improving accuracy, reducing steel use, and supporting safer building design.
Results
- Faster daily engineering work
- Lower steel usage
- Reduced environmental impact
Ground Station Software: Safer Flights, Smarter Maintenance
Modernized ground station tools that help maintenance crews detect issues earlier, reduce costly surprises, and strengthen fleet readiness across civil and defense aviation.
Results
- Safer, more predictable operations
- Lower maintenance costs
- Improved global fleet readiness
Manufacturing Simulation Software Made Simple
A unified desktop tool that replaced three separate systems, reduced duplicate work, and made simulation modeling faster, clearer, and easier for engineering teams.
Results
- One tool instead of three
- Faster, easier simulations
- Higher adoption across team
Let’s build something that lasts.
