Hi, I’m

Samuel Sánchez.

Software development · automation · AI

I build software that connects systems, makes sense of data and automates repetitive work. From the API to the dashboard, from the script to the app.

Right now: building apps for bady

// 01 · About [01/05]

Where I come from
and how I work.

I’m a developer with a background in Python, SQL and API integration. I like data that arrives on its own, gets processed properly and is clear at a glance.

I’ve built apps that read public data in real time, a system that forecasts electricity demand and, now, my own apps for iPhone and Mac. I work in agile teams, with Git and with a lot of care for detail.

// 02 · What I do [02/05]

Three things,
done well.

01

Automation & integration

I connect your tools through APIs, pull data from wherever it lives and replace manual tasks with Python scripts and services.

  • Python
  • REST APIs
  • FastAPI
  • SQL
02

Mobile apps & websites

Apps for iPhone, iPad and Mac, and fast websites, with their own backend so you can update the content yourself.

  • Flutter
  • SwiftUI
  • JavaScript
  • HTML/CSS
03

Data & applied AI

Analysis, dashboards and forecasting models. I add language models to real products, with secure calls from the server.

  • Pandas
  • Prophet
  • Streamlit
  • LLMs
