Freelancer profile translated to English.
Back to original languageAbout Antonin
I work on existing software systems that are becoming difficult to maintain, diagnose, or stabilize.
Typical Missions
- Debug critical bugs, crashes, freezes, watchdog resets, and unstable behaviors
- Stabilize legacy C/C++ code
- Linux diagnostics: logs, services, scripts, processes, performance, runtime errors
- Embedded systems, IoT/edge, Raspberry Pi, inter-module communication, MQTT/WebSocket
- Codebase takeover, technical audit, documentation, and action plan
- Gradual modernization without risky rewrites
What I Bring
I help teams understand why a system crashes, why a behavior is intermittent, where the technical risk lies, which investigations to prioritize, and how to improve logs, observability, and reliability.
Possible Formats
Short mission, technical support, audit/stabilization of existing codebase, or triage sprint for unstable embedded systems: symptoms, logs/traces, failure hypotheses, instrumentation, and action plan.
Possible Deliverables
Diagnostic report, prioritized hypotheses, instrumentation recommendations, targeted fixes, diagnostic scripts, technical documentation, and stabilization plan.
Mission Examples
- Audit of a C/C++ or embedded Linux codebase
- Analysis of a crash or unstable behavior
- Correction of critical bugs
- Implementation of logs, diagnostic scripts, or monitoring
- Takeover of an IoT / Raspberry Pi / real-time backend project
- Technical support on C, C++, Linux, Git, or software architecture
Main Stack
C, C++, Linux, embedded systems, IoT/edge, Raspberry Pi, MQTT, WebSocket, Docker, Git, CI/CD, Python, Bash.
Complementary Skills:
Java/Spring Boot and Flutter for backend, HMI, or mobile integration.
I prefer missions where the need is clear: stabilize, diagnose, take over, make reliable, or deliver a technical component cleanly.
