Back to original languageAbout Helmi
With over 15 years of experience in software development and architecture, including a role as a transverse architect and tech lead within the BPCE banking group, I have managed and deployed numerous critical applications. I master engineering best practices (SOLID, software craftsmanship, CI/CD, security, monitoring, observability) and I now help companies build truly reliable, robust, and production-ready AI systems.
At ShiftAI, I support SMEs, startups, and large corporations in designing:
- Operational AI agents (Langchain, LangGraph),
- Multi-agent systems (Langgraph, CrewAI, PydanticAI),
- RAG chatbots (based on need: Simple RAG, Agentic RAG with a good chunking and ranking strategy),
- And complete AI applications integrated into their environments (CRM, finance, support, operations…).
My approach combines classic software architecture and advanced agentic architecture.
I don't deliver prototypes: I design industrialized, supervisable, observable, and business-aligned AI systems.
Monitoring, traceability, explainability, metrics, software quality… everything is considered from the start to ensure a stable, scalable, and reliable solution in production.
Project examples:
- Business copilots,
- Advanced automation,
- Personalized AI assistants,
- Chatbots connected to internal data,
- Fullstack AI applications & multi-agent orchestrations.
My goal: transform your ideas into concrete, high-performing, and production-ready AI solutions, with an approach blending technical expertise, architectural rigor, and agentic innovation.
