Back to original languageAbout Alexandre
I help you leverage your data to save time, better manage your business, and create value.
Your data is often scattered (CRM, Excel files, SaaS platforms) and difficult to transform into useful information. My role is to centralize it, automate its processing, and make it accessible through clear dashboards and analyses.
With two years of experience as a Data Engineer through apprenticeships, I have worked on creating ETL and reverse ETL pipelines, workflow orchestration, dashboard development, and setting up predictive models. I can also assist you with generative AI projects (RAG, LangChain, Qdrant, LlamaIndex).
- Setting up ETL and automating data flows
- Orchestrating processing workflows
- Creating dashboards (Power BI, Superset, Excel)
- Developing prediction and classification algorithms
- Integrating AI solutions based on RAG
