I will build data dashboards and apis with python and sql


About this gig
I build end to end data products you can use in real work. From raw files or a public source, I clean and normalize the data, design an efficient SQL model, and deliver a clear interactive dashboard. When needed I expose results through a simple FastAPI endpoint so your team or tools can reuse them.
Stack: Python, SQL, Plotly Dash, FastAPI, PostgreSQL or Supabase, Docker. I keep the setup simple, reproducible and well documented.
What you get: a cleaned dataset, analytical SQL views or functions tuned for speed, a Dash dashboard with filters and exports, an optional API endpoint, and a short README plus a brief video walkthrough.
How I work: we define scope by outcomes, agree on small milestones, and start with a thin working example to align early. Communication is direct and concise. I hand over a private repository the client controls.
Fluent in English and Spanish. Based in Madrid and fully remote.
Send me your goal, sample data or a link, and any constraints. I will reply with a simple plan and the first milestone.
