Expert Qt Development Services (QML & C++)
You've chosen Qt for its power. Now, partner with a team that can harness it. Gravitonic builds high-performance, production-ready Qt applications for your most demanding embedded and desktop projects.
We are the Qt experts who can deliver your vision, on-time, with the performance and quality your product deserves.
Qt is Powerful, But "Good Enough" Qt Teams Fail.
Choosing Qt is the right move for a high-performance, cross-platform UI. But hiring a generic C++ developer or a web agency "who knows some QML" leads to disaster.
These projects always fail in the same ways:
Crippling Performance & Lag
The UI is laggy, animations stutter, and the boot time is unacceptable. Your "fast" Qt application feels slow and cheap because the team didn't understand QML rendering loops, C++ backend binding, or GPU optimization.
The "QML to C++" Chasm
Your QML front-end team and your C++ backend team can't communicate. The UI logic is a tangled mess, C++ integration is a bottleneck, and the entire application becomes an unmaintainable "Big Ball of Mud."
Embedded Deployment Nightmare
Your app runs fine on a desktop, but it's unusable on your target hardware. The team has no experience with Embedded Linux, Yocto, cross-compilation, or optimizing for a specific system-on-a-chip (SoC).
Broken "Figma to QML" Workflow
Your UI/UX team delivers beautiful Figma mockups that are impossible to implement in QML. Your developers are forced to cut corners, and the final product looks nothing like the design you approved.
Gravitonic: Your Elite Qt Development Partner
We are not generalists. We are a specialized team of Qt and C++ experts. We build complex, mission-critical Qt applications for industries where performance and reliability are non-negotiable.
1. Full-Stack Qt Application Development
We build the entire application. Our expertise spans from a pixel-perfect, fluid QML front-end to the robust, multi-threaded C++ backend logic. This unified approach ensures your application is seamless, maintainable, and powerful.
2. Qt for Embedded Devices
This is our specialty. We are masters of Qt for Embedded Linux. We manage the entire embedded stack, from creating your custom Yocto or Buildroot image to optimizing your application for a specific NXP, ST, or Renesas processor.
3. UI/UX Design for Qt
Our in-house UI/UX design team doesn't just use Figma; they think in QML. They design interfaces that are not only beautiful and intuitive but are also highly performant and feasible to build, eliminating the "design-to-dev" gap.
4. Qt Performance Optimization & Project Rescue
Is your current Qt project slow, buggy, or over-budget? We are the experts you call to fix it. We will profile your application, identify bottlenecks (in QML, C++, or rendering), and refactor your code for maximum performance.

Why Gravitonic for Your Qt Project?
We are more than just a C++ shop. We are a strategic partner that de-risks your most complex Qt projects.
We are Qt Performance Specialists
We live and breathe performance. We know how to optimize your QML rendering, write efficient C++ bindings, and leverage every ounce of your hardware's GPU. We build 60-fps UIs on hardware where other teams fail.
We are Embedded Systems Experts
We are not app developers. We are embedded engineers who understand cross-compilation, memory profiling, kernel drivers, and bare-metal constraints. We build Qt applications that integrate flawlessly with your hardware.
Seamless UI/UX & QML Workflow
Our designers and developers work as one unit. We create QML-ready design systems and components, ensuring your UI is not only stunning but also lightweight and perfectly matches the approved design.
Proven Mission-Critical Expertise
We bring our expertise from building safety-critical HMIs in the medical, automotive, and industrial sectors to your project. This means a disciplined approach to code quality, testing, and reliability.

Frequently Asked Questions (FAQ)
Why should we choose Qt for our HMI?
You made the right choice. Qt provides a single, high-performance C++ codebase that can be deployed anywhere—from a powerful desktop to a resource-constrained embedded device. Its QML technology allows for the creation of fluid, modern UIs that are unmatched by older or web-based tech.
Can you build Qt apps for microcontrollers (MCUs)?
Yes. We are experts in Qt for MCU. This allows us to bring a rich, smartphone-like GUI to low-power, low-cost microcontroller-based products where it was previously impossible.
Our in-house team is struggling. Can Gravitonic help?
Yes. We offer both team augmentation and project rescue. We can integrate our senior Qt experts into your existing team to provide leadership and expertise, or we can take over a struggling project to get it back on track and across the finish line.
What's your process for turning a Figma design into a QML UI?
Our UI/UX team designs for QML. We create a style guide and component library that translates directly to reusable QML components. This means the developer isn't guessing—they are assembling a pre-optimized, design-approved toolkit, ensuring 1:1 fidelity with the final design.
