Applied AI and agents
Assistants and agents built on self-hosted open-weight models and wired to real data and tools — keeping cost and privacy under control.
Connecting the present to the future
Independent lab for software, AI and GIS
AI agents, geospatial platforms and web products — designed, built and run on our own infrastructure.
Focus
Areas of work
Geographic information systems
PostGIS, QGIS Server and QGIS plugins: field data collection, validation and publication of territorial data. Since 2008.
Platforms and infrastructure
Laravel, React and Node applications on Docker, with HTTPS, backups and monitoring — from prototype to production.
Projects
Selected work
Own projects, in use or in development. The status shown is the real one.
GeospatialIn development
GroundControl
Platform to collect, validate and publish geospatial data: a PostGIS-backed API, a field app that works offline and a QGIS plugin to prepare and sync projects.

Jessica
Operational AI assistant: interprets server output using context, operational memory and runbooks. Runs on self-hosted open-weight models.
MobileBeta
TugaSSH
Native Android app for SSH server administration, with keys stored in the Android Keystore, an interactive terminal and Jessica built in for assisted diagnostics.
PlatformInternal tool
TugaDemo & TugaMVP
From meeting to live URL in minutes: a CLI that scaffolds, deploys and hosts demos (Vite + React) and working MVPs (Laravel + PostgreSQL), each on its own HTTPS subdomain.
SaaSInternal engine
TugaSG
Software Generator: a multi-tenant engine for vertical platforms — one codebase generates the website and back office for many clients in the same sector, each with its own domain and modules per plan. The engine behind products that grew into brands of their own.
Approach
Principles
Self-hosted by default
Services run on servers in the European Union and on our own hardware, administered directly. Local AI models whenever the task allows.
Private by default
This site uses no cookies and no third-party resources. Analytics are self-hosted, anonymous and cookie-free.
Documented and recoverable
Infrastructure described in versioned runbooks, off-site backups several times a day and continuous monitoring.
