Twelve projects of our own with open source: data and BI, AI, web development and security. Each one backs a service in the catalogue.

Data and BI

  • Executive dashboard — Twenty-four executive indicators on one screen, and they all reconcile.
  • Customer churn — A model that flags which customers are about to leave, and what is pushing them.
  • Sales and weather ETL — Does the weather move sales? The answer lives in the join between two sources nobody designed to be combined.
  • Profitability in SQL — Ten thousand sales lines and one question: what sells a lot and earns little.
  • Hotel pricing engine — Six demand signals set the rate for every room, every night.

AI and automation

  • AgentForge — Infrastructure to stand up one AI agent per client without building it from scratch each time.

Web and interface

  • Revenue simulator — The pricing levers turned into sliders that recalculate revenue instantly.
  • Cinematic web — Turns a flat website into a landing page with cinematic motion, in a day or two.
  • A restaurant in 3D — Real three-dimensional models, with rendering cost controlled scene by scene.
  • Interactive portfolio — The projects on this page, turned into dashboards you explore in the browser, with nothing to install.

Security

  • Log analysis — Parses 5,000 synthetic security events and summarises them into an incident report with four tables.
  • Vulnerability scanner — Simulates a port scan and turns the open ports into prioritised findings, with severity and mitigation.

Open-source libraries

  • VeriFactu hash chain — The chained SHA-256 hashes VeriFactu requires, computed in Python with not a single dependency.
  • Spanish tax calendar — When each Spanish tax form falls due, computed rather than copied from a table.
  • Facturae in Python — The electronic invoice XML Spanish law makes mandatory, generated from Python.
