NEW SKILL UNLOCKED: OpenClaw (formerly Clawdbot and Moltbot).

With over 30 successful projects on Upwork, I help clients tackle data analytics, automation, and AI challenges. Nowadays, AI is a requirement in almost any field, and therefore, clients look for someone capable of understanding new technologies such as Agents, multi-RAG systems, and prompt engineering.

Aligned with that, they also need a professional who excels in web scraping, data preprocessing, and backend engineering, as well as a bit of front-end development, particularly when it comes to displaying insights with dynamic dashboards or designing chatbots for the RAG systems.

I’m a Swiss-Army Knife when it comes to data and Python, with a strong, proven 5-star record of work. I also speak French 🇫🇷, Spanish 🇪🇸, and Portuguese 🇵🇹.
