Description

🔹 About

Expert C++ / Qt specializing in embedded Linux systems, I help R&D teams solve complex performance, stability, and industrial communication issues.

I step in where projects slow down or get blocked:

- Slow or unstable Qt/QML applications

- Difficult-to-diagnose bugs

- Uncontrolled latency and performance

- Unreliable CAN / sensor communication

My goal: quickly unblock critical situations and improve overall system quality.

🔹 Expertise

C++ / Qt / QML

- Qt 5 / 6, Qt Quick

- C++ ↔ QML Integration

- Real-time interfaces, industrial dashboards

Performance & Optimization

- CPU / GPU analysis (profiling)

- Qt/QML graphical rendering optimization

- Reduction of latency and memory consumption

Embedded Linux

- ARM deployment

- System debugging, logs, instrumentation

- Constrained / real-time environments

Industrial Communication

- CAN bus, CANopen, SocketCAN

- Frame analysis and diagnostics

- Sensor integration and data acquisition

🔹 Typical Projects

- Development of real-time Qt/QML applications

- UI and rendering performance optimization

- Debugging complex bugs (crashes, latency, instability)

- Making CAN / sensor communication reliable

- Embedded software architecture

🔹 Intervention Modes

- R&D team augmentation

- Technical / performance audit

- Critical bug resolution

- QML / UI architecture overhaul

- Fast and incremental delivery

🔹 Quick Interventions (High ROI)

Qt/QML Performance Audit (½ day)

→ bottleneck identification + concrete action plan

CAN / CANopen Debugging

→ frame analysis + correction + validation

Qt/QML Project Setup

→ clean architecture + best practices + tooling

I am currently the lead for embedded weighing systems:
In material quarries (sand, gravel, stones, etc.), loading machinery (loaders) are equipped with systems to measure the weight loaded into trucks.

I actively participated in the design and development of all display screens for the embedded weighing system.
I developed an Android Kotlin system to communicate via CAN with an ECU and CANopen sensors.

I am currently the lead for embedded weighing systems:
In material quarries (sand, gravel, stones, etc.), loading machinery (loaders) are equipped with systems to measure the weight loaded into trucks.

I actively participated in the design and development of all display screens for the embedded weighing system.
- I actively worked on performance improvements to achieve fluid software, even with large amounts of data.
- As the system is certified, I developed and documented its operation to obtain certification from LNE (National Metrology and Testing Laboratory).
- I developed and optimized the automatic data upload to a remote server via 4G modems.

Key achievements:

Complete design of a QML/QtQuick interface for an embedded tool.
C++ backend integration for real-time acquisition and processing.
Creation of custom UI components: dynamic graphs, touch controls.
Improved UI stability and reduced latency.
