Samir Saci Team Lead

CEO at LogiGreen
100% of the output Designed and built the entire project end-to-end as a solo contributor. I implemented: • The FastAPI backend (speech-to-text, pronunciation analysis, TTS, routing) • Integration with Google Gemini (Pinyin extraction + image generation) • AI agents inside n8n using Mistral AI and structured output parsers • Telegram bot orchestration and interactive learning flows • Google Sheets data pipeline for vocabulary management • All workflow logic, prompts, error handling, and system design • Infrastructure setup on a VPS using Docker Sponsor tools used: Google Gemini API, Mistral Cloud API, n8n workflow engine, Telegram Bot API.
I’m a supply chain engineer and data scientist turned founder of LogiGreen, a startup based in Paris. We build analytics and AI-driven tools to help companies optimize logistics operations while reducing their environmental footprint. Before founding LogiGreen I worked internationally in China and Europe in solution design and performance management. I also write and teach about supply chain analytics, automation and sustainability through my blog, open-source tools and online content.
I'm interested in AI agents and workflow automation for real-world operations: supply chain, logistics, sustainability and SME tooling. I’d like to meet people working on agent orchestration (n8n, LangGraph, MCP, etc.), speech + multimodal interfaces, and applied optimization. Open to collaborating with founders building AI-native products for industry and B2B ops.
I’m building an AI language-learning assistant for professionals. The idea is a Telegram tutor that helps foreigners working abroad in a new language learn business and daily-life vocabulary. It uses n8n plus Mistral and ElevenLabs for exercises, feedback and pronunciation coaching. For the prototype I’ll use Chinese as an example, based on my own learning journey.
