LOTFI S.

I help businesses build AI-powered systems that actually work in production. With 15+ years of experience as a Tech Lead in enterprise systems (banking, government, ERP), I now specialize in integrating Large Language Models (LLMs) into real-world applications. My focus is not just AI — but making AI usable, scalable, and reliable inside your systems. What I can help you with: ✔ Build AI Agents using LangChain and RAG architectures ✔ Develop intelligent chatbots and Q&A systems using your data ✔ Integrate LLMs (OpenAI, open-source) into your backend systems ✔ Fine-tune LLMs using modern techniques (LoRA, QLoRA, PEFT) ✔ Design and build scalable APIs for AI-powered applications ✔ Automate business workflows using AI + backend logic ✔ Connect AI with databases, documents, and enterprise systems Technical stack: * Python, LangChain, Hugging Face, Transformers * RAG pipelines, vector databases * LLM fine-tuning (PEFT, LoRA, QLoRA) * Java, Spring Boot, REST APIs * SQL / NoSQL databases * Workflow systems (Camunda, BPMN) Why work with me? * Strong backend & architecture expertise (not just AI prototypes) * Experience building complex enterprise systems * Focus on clean, maintainable, production-ready solutions * Ability to understand business processes and automate them with AI If you're looking to move from AI idea → working system, I can help you get there. Let’s discuss your project.
