Technical support — sheet metal CAD/CAM
Support and maintenance of CAD/CAM systems and the surrounding infrastructure. Nesting algorithm tuning, post-processor configuration, machine-specific workflows.
Available for consulting and new projects — since July 2026

01ABOUT ME
Ten years in industrial IT.
Eight of them next to the people cutting the metal.
I started in enterprise IT consulting (Aubay, Turin): systems administration and batch procedures on banking and insurance systems that have to run every single night. It is a good start — it teaches you rigour and respect for systems that cannot afford to get it wrong.
Then I moved into digital manufacturing: eight years of technical support on sheet metal CAD/CAM software — seven at Lantek, the last one at Libellula — alongside operators, programmers and production managers. That is where I learned the other half of the trade: seeing how a software decision turns into a real problem at the machine, and how it actually gets fixed.
Today I work independently, for companies and individuals, on bespoke software, on-premise infrastructure and local AI. And I build DCAM, which is the test bench where everything I learn ends up.
EXPERIENCE
Technical support — CAD/CAM systems
Seven years on enterprise nesting and CAM solutions at industrial clients, across multiple plants. Nesting algorithms, post-processors, CAM-ERP integrations, vendor relationships.
IT systems and support
Systems administration, network configuration, Linux and Windows servers. Batch procedures on mission-critical banking and insurance systems. Java fundamentals and web development.

THE PROJECT
A CAD/CAM that lives in the browser.
One product on Windows, macOS, Linux, web and tablet. You open an address and you work: no installation, no licence tied to one machine.
DCAM comes out of eight years spent seeing what a workshop actually needs and what is only in the brochure. It drafts, nests the parts on the sheet, applies the cutting technology and writes the program the machine runs — from drawing to CNC without switching software.

WHAT IS INSIDE
The CAD
Full 2D drafting: dimensioning, layers, blocks, geometric constraints, DXF and DWG import and export.
HowTypeScript and Rust/WebAssembly. Entities are SVG — so printing and PDF come out as vectors — and the live cursor work sits on canvas.
The nesting
Arranges parts wasting as little material as possible. It is where a CAM earns or loses the client's money: one point of scrap, over a thousand sheets, is a whole sheet.
HowSeveral engines competing on the same job, including the one holding the published records in the literature, compiled to multi-threaded WebAssembly inside the browser.
The CAM
Lead-ins, micro-joints, cutting sequence, tool compensation, cut quality, part unloading: what turns a nesting layout into a program a machine will run.
HowDifferent dialects for different manufacturers — Siemens 840D, Fanuc macros, Euromac — worked out from the manuals and the real configuration files, not by guessing.

TECHNOLOGICAL SOVEREIGNTY
Your own servers instead of rented cloud.
I help companies keep their own systems in-house: on-premise infrastructure, AI models running on their hardware, data that never leaves the company. Application, database, mail, continuous integration and this very page run on my own hardware — you are using it right now.
04LET'S TALK
Let's talk.
I like to know who gets in touch. Drop me a couple of lines about what you do and what you need: I answer quickly. I work remotely, on-site when it makes sense — for consulting, fixed projects, one-off work or a permanent role.
