Habita Barcelona

Sole engineer at a Barcelona real-estate and investment firm. I design, build and run its connected production systems, and make the technical decisions with the founders.

• INMA, the CRM: 9,400+ portal leads from January to October 2026. Leads get a WhatsApp in 2.1 s (median) and screen themselves on a form, so agents save a great deal of time and only write to the ones worth writing to.
• INMA Search Service, a new paid business unit: tenants say once what they need, and deterministic matching alerts them when a flat fits. 677 active seekers in November 2026.
• habitabarcelona.com, rebuilt from WordPress to Next.js: 171 listings and 4,700+ photos migrated, 272 old URLs redirected to keep the search ranking, and every enquiry goes straight into INMA.
• MathProperty, the investment platform of the firm's property company: ~30 properties, with a Python ETL that moved years of Excel history into it.
• Safe by design: row-level security and encryption in the database, signed webhooks, audit trails, and real-time alerts on every server error.
• Built with AI coding agents, given context generated from the live database schema; they reach production data only through prewritten interfaces, and every write needs human approval.
