About Me
From Fortune 500 to Freelance: My DevOps Journey
Senior Software Engineer & DevOps Expert
I'm a Senior Software Engineer specializing in Go microservices, DevOps automation, and AI/LLM integration, based in France and working remotely with global clients.
With 4+ years at Fortune 500 companies like IQVIA and various startups, I've built scalable backend systems and cloud infrastructure that handles millions of users while optimizing costs.
I can work on Go development, DevOps engineering, or both - whatever your project needs. My approach focuses on building robust, maintainable systems with proper automation and monitoring.
I also specialize in AI/LLM integration and agentic workflows, helping companies leverage OpenAI and LangChain for intelligent automation and business process optimization.
