Technical suite for construction: 48 calculators across 10 modules following CIRSOC, IRAM and CABA/PBA building codes. Materials, structure, installations, layout and site management, with budgeting and PDF export. Works offline and installs as an app.

End-to-end lead capture and sales system for construction companies: the site captures, a configurator qualifies the prospect and estimates square metres, AI scores the lead, and a self-hosted CRM handles pipeline, calendar, quotes, projects and expenses. Automated email and WhatsApp follow-up always goes through human approval before going out. Running in production at DV3 Construcciones, the studio I am part of; the replicable version for rolling it out to other companies is in progress.

Video analytics that runs on the cameras a client already owns. It detects people and vehicles, and a rules engine —by zone and by time of day— decides what deserves an alert: in the reference test, 56 detections produced 2 events. The value is in what is NOT notified, because a control room flooded with a hundred alerts a day stops looking at the one that matters. Every alert ships with a still and a clip, so the operator can actually decide. The panel follows ISA-101, the control-room interface standard —colour is a signal, not decoration— and the installer draws zones straight onto the live image instead of computing pixels by hand. It runs on a box inside the site: no internet, no third-party dependencies.

Multi-agent system for a construction company: an orchestrator receives a request, routes it to the right domain agent —site, finance, procurement, legal, HR— and consolidates the answer. Agents query a RAG base with IRAM and CIRSOC standards, manuals and project history. The 3D office is a navigable building where each floor is a domain and each desk an agent: instead of a list of 55 names, you see who works on what. The orchestrator, agent registry and dashboard work today; the 55 agents are defined and ERP/BIM integration is in progress.

Management system for construction companies: quotes, projects, progress certification, crews, suppliers, payments and sales pipeline in one place. Multi-tenant —several companies run isolated on the same server— with role-based access: crews report progress with photos but never see the money, and nothing takes effect without approval. 44 endpoints and 28 screens. Finished, pending launch.

Stock, inventory and quoting software for small shops, built so the owner can use it without any technical knowledge. One codebase ships two products: a web version that installs from the browser onto a phone —for shops run from the counter with a phone in hand— and a Windows application with its own installer. Both work offline, and the same licence key works on either. Every sale discounts stock automatically, quotes come out with the shop logo ready to send over WhatsApp, and it flags what needs restocking before you run out. It ships with eight preconfigured trades —from corner shop to builders merchant, each with its own way of selling: by unit, by metre, by square metre, or parts plus labour—. Licences are signed with a private key that is never distributed. Sold as a one-time payment, not a subscription.

Website for a design & construction studio in Pilar: project portfolio, services, coverage areas and its own blog. Includes a configurator that builds a ballpark quote and captures the lead, wired into the studio's sales follow-up system.

A platform for pet tracking and management: identification, history and alerts in one place. On hold pending the tracking hardware.

A CRM designed from inside the real estate business: properties, clients and sales follow-up with AI assistance.

AI-powered automation flows for customer service, inquiry triage and repetitive tasks.

Experimentation space: games, apps and prototypes where new ideas are tested before becoming products.
