Back to original languageAbout Yatma
I don't just analyze your data, I build the autonomous systems that leverage it.
Data Engineer by training (PhD) and e-commerce entrepreneur for 10 years, I have a rare dual expertise: I fully understand your business challenges (ROI, acquisition, scalability) and I master the technical skills to solve them.
Today, I support companies in their digital transformation by creating tailor-made applications and automating their time-consuming processes.
MY AREAS OF EXPERTISE:
Automation & AI (Backend): Creation of complex workflows (n8n, Make), AI Agents (OpenAI, Claude) for prospecting, customer service, or automated content management.
Web Development (Frontend): Creation of business applications, SaaS interfaces, and custom interactive Dashboards (React.js, Tailwind).
Data Analysis & Engineering: ETL pipelines, Scraping, database structuring (PostgreSQL, BigQuery), and creation of interactive Dashboards (Power BI, Looker Studio) for decision-making.
DevOps: Secure deployment on VPS servers (Docker, Traefik, Nginx, Linux).
WHY WORK WITH ME?
No more service providers who do "just one thing." I can design your project from A to Z: from raw data extraction to its presentation on a modern, robust, and secure web application.
Have an automation or development project? Send me a message to discuss it, I usually respond within the day.
