Software Development

Since 2015, we design and build custom software for companies that need concrete, secure, cloud-independent solutions. Every project starts from a real need — no templates, no compromises.

What we do, concretely

We're not a web agency reselling templates. We are developers, software architects and AI specialists who build applications from scratch, designed to last. We work closely with each client: from the first brief to production deployment, every technical decision is made together.

Over ten years we've built vertical management systems, AI platforms, document automation systems and creative tools. Everything you see on this site — from RAG Enterprise to CRM81 — was designed, developed and maintained internally by our team in Milan.

What we've built

Three platforms born from real client needs, now running in production.

RAG Enterprise

Upload PDF, DOCX, TXT with integrated OCR (Tika + PyMuPDF)
Hybrid search: BM25 + vector + Re-ranking with Cross-Encoder
Local LLM via Ollama — Llama 3, Mistral, Phi and more
Qdrant vector database for semantic similarity
Multi-Query Retrieval for complex questions
Integrated analytics dashboard with conversation history
Deploy with Docker Compose in under 5 minutes
Open source Community Edition (AGPL-3.0) on GitHub

What we can build for you

Every company has different processes. We study them, simplify them and turn them into software that works. Here are the areas where we step in most often.

Vertical management systems

Software built around your specific industry. We don't adapt a generic product — we design it around your operational flows. CRM, ERP, ticketing systems, inventory management, automatic invoicing.

On-premise AI platforms

We integrate local language models (LLM), computer vision and RAG systems directly into your infrastructure. Your data stays on your servers — no external cloud dependency.

Document automation

Systems that read, classify and process documents automatically. OCR, data extraction from PDFs, automatic report and contract generation. Concrete time savings every week.

Legacy system integration

Connecting old and new software without data loss. API bridges, custom middleware, progressive migration. Your 2000s management system can talk to a modern dashboard.

Dashboards and business intelligence

Real-time control panels with aggregated data from multiple sources. KPIs, interactive charts, automatic alerts. Decisions based on data, not gut feelings.

Automations and workflows

Manual processes turned into automatic flows. Notifications, approvals, cross-system sync, recurring tasks. Fewer human errors, more time for work that matters.

Web portals and applications

High-performance single-page applications with React, client portals, restricted areas, B2B e-commerce. Modern frontends that integrate with any backend.

Compliance and security

Software designed to meet GDPR, ISO 27001 and industry regulations from day one. Audit trails, encryption, granular permission management. No compromises on security.

Our tech stack

We choose the best technologies for each project — not the trendiest ones.

How we work

1

1. Analysis and listening

We always start from an honest conversation. We understand the problem, the constraints, the budget. We don't sell pre-packaged solutions — we listen first, propose after. Often the right solution is simpler than what the client imagines.

2

2. Working prototype

In 2-4 weeks we build a real prototype, not a static mockup. Show it to your team, test it with real data, tell us what works and what doesn't. Fast iterations, no months of waiting to see something functional.

3

3. Incremental development

We release features in blocks, every 2-3 weeks. The software grows organically, guided by real user feedback. No surprises at final delivery — because there's no "final delivery", there's a product that continuously improves.

4

4. Deployment and training

We install the software on your infrastructure (or on servers we manage), configure monitoring and backups, train your team. We don't leave you alone with a PDF manual — we stay available for support and updates.

5

5. Ongoing maintenance

Software doesn't end when it goes to production. We update dependencies, optimize performance, add requested features. Our support is included because we believe in long-term client relationships.
