Data engineering for Vallès SMEs
Scattered data → decisions with traceable SQL. No endless consultancy.
Vallès SMEs often have an ERP, spreadsheets and a half-built BI. Our data engineering prioritises one value block: inventory, close or reporting — with a 10-day pilot.
D4TA Oracle (Chat-to-SQL) is often the first product: ask in plain language, get the exact figure and the SQL that ran on PostgreSQL or ERP exports.
If you are looking where to start with data engineering in Terrassa or Sabadell, start with the process that burns the most hours today.
