Freelancer profile translated to English.
Back to original languageAbout Nicolas
I design and operate production-grade machine learning and data systems in multi-cloud environments, with a primary focus on Azure and hands-on experience with GCP and AWS.
With a background as a Data Solutions Architect and Lead Engineer, I specialize in building scalable, event-driven architectures. I leverage Kafka, Spark, Python, Java, and Scala to power real-time enterprise systems.
My scope includes:
- Cloud-native architecture (Azure, GCP, AWS)
- Real-time streaming and large-scale data processing
- ML system design and production deployment
- Prototyping AI agents and MCP-based solutions in enterprise environments
Currently, I am leading exploratory initiatives on AI agents within a large corporation — designing prototypes, evaluating tools, and guiding internal teams to measure how agentic systems can generate tangible business value.
My goal is to bridge robust cloud infrastructures with emerging AI capabilities to deliver secure, scalable, and production-ready systems.
