You will get Custom Linux GUI Tool (Bash or Python)
Project details
Stop using complex command-line scripts that confuse your team. I will build you a simple, clean, and robust Linux Desktop GUI tool to automate any repetitive task.
Leveraging my 20 years of experience as a Linux Expert, I build lightweight, efficient tools using Bash/Zenity (for a 100% native Linux feel) and Python/customtkinter (for modern, beautiful interfaces).
This service is 100% specialized for Linux (Ubuntu, Debian, etc.).
This forfait is perfect for:
• Automated Backup Scripts
• File Converters (CSV to JSON, XML parsing, etc.)
• Simple TCP Client/Server Testers
• Automating any repetitive business process
• Creating simple front-ends for complex hardware or processes
My process guarantees your 5-star satisfaction:
• Step 1: Scope & PDF Mockup: We validate your exact needs and I provide a PDF mockup (visual layout + functional scope) for your 100% approval before I write any code.
• Step 2: Development: I build your tool, providing mid-point updates for Standard/Advanced tiers.
• Step 3: Delivery: You receive the complete, commented source code and a clean README file."

C++/Qt/Python Architect | Desktop Apps, API & Data | 20Yr Remote EU
Paris, France - 6:48 am local time
I transform complex technical challenges into high-performance, scalable software solutions. With 20 years of experience in industrial systems, robotics, and data processing, I deliver robust applications that perform.
As a senior architect with deep expertise in both C++ and Python, I help companies build reliable, maintainable software systems. I specialize in performance-critical applications, cross-platform desktop tools, efficient APIs, and data processing pipelines.
🎯 CORE EXPERTISE
✅ PERFORMANCE OPTIMIZATION
Transform slow processes into fast, efficient systems. From Excel bottlenecks to C++ real-time constraints, I identify and eliminate performance issues through profiling, multithreading, and Python/C++ binding. I've optimized systems processing millions of data points in real-time with sub-100ns precision.
✅ APPLICATION DEVELOPMENT
Cross-platform desktop applications (Qt/PySide, Linux/Windows/macOS), APIs, and backends. Clean architecture, maintainable code, production-ready quality. I build applications that users rely on daily, from industrial robotics control systems to data analysis tools.
✅ DATA PROCESSING & AUTOMATION
Python tools for data analysis and visualization (Pandas, NumPy, Plotly, PyQtGraph). SQL databases (PostgreSQL, SQLite, DuckDB) for handling massive datasets (100M+ rows). Data pipelines and automation scripts that eliminate manual processes. I turn repetitive tasks into automated workflows, saving hours of manual work.
✅ ARCHITECTURE & APIs
Design scalable software architectures and robust APIs. From prototype to industrial-grade systems, I ensure your architecture can grow with your business. RESTful APIs, microservices patterns, clean separation of concerns. I've architected systems handling 1M+ connected sensors in distributed environments.
✅ C++ / PYTHON INTEGRATION
Unique expertise in combining C++ performance with Python flexibility. Python/C++ bindings for performance-critical modules, mixed development strategies, optimal technology choices for each component. This dual expertise allows me to choose the right tool for each part of your system.
✅ EMBEDDED & REAL-TIME SYSTEMS
Linux embedded systems (Yocto, Debian, Ubuntu), VxWorks, uC/OS-III. Real-time constraints, ultra-precise synchronization, custom network protocols. TCP/IP industrial communications, robotics protocols (ABB, KUKA, FANUC). Low-level optimization, driver development, hardware integration.
📊 PROJECT DETAILS
VisionNerf (2019-2023): C++/Qt/Linux 3D vision systems for industrial robotics (ABB, KUKA, Fanuc). Automotive industry. TCP/IP protocols, CI/CD, 90% reduction in returns.
Sercel (2010-2019): Software architecture for distributed seismic networks (+1M sensors). Real-time C++ (Linux/VxWorks/uC/OS-III), ultra-precise synchronization.
Thales (2007-2010): DO-178B Level A avionics software and defense cryptography. Fixed critical 10-year latent bug.
✅ WHAT I DELIVER
- Performance-critical applications (C++ expertise, 20 years)
- Cross-platform desktop applications (Qt/PySide, Linux/Windows/macOS)
- Data processing pipelines and automation (Python, SQL, Pandas)
- Clean architecture and maintainable code

📩 Let's discuss your project. I deliver results, not excuses.
Steps for completing your project
After purchasing the project, send requirements so Samuel can start the project.
Delivery time starts when Samuel receives requirements from you.
Samuel works on your project following the steps below.
Revisions may occur after the delivery date.
1. Requirements & GUI Mockup Validation
First, we confirm all requirements. Then, I will create and send you a simple PNG mockup (visual layout + functional description) for your 100% approval. (Note: This is a scope validation, not the technical algorithm.)
2. Development & Testing
Once you approve the mockup, I will build your custom tool and perform rigorous unit and integration testing. For Standard & Advanced Tiers, I will provide a mid-point update (screenshot/video) to ensure we are aligned.
