I turn industrial complexity into software that works. From combinatorial optimization to AI-assisted pipelines — I build tools that make hard operational problems disappear.

About

Engineer
who
ships.

I'm a Management Engineer with a strong lean toward process digitalization, operations research and AI. My work sits at the intersection of industrial logic and software craft — I analyse how things actually work, find where the friction is, and build tools that remove it.

Over the past year I independently designed and deployed a full suite of industrial applications in a real healthcare infrastructure company — solving NP-hard optimization problems, automating logistics planning, structuring a 85,000-record database, and experimenting with local LLM and RAG architectures. Every tool was born from direct observation of a broken process, and validated in production.

I work through rapid prototyping and iterative validation. I care about the quality of the data, the coherence of the flow, and the elegance of the result.

Projects

What I've
built.

08 tools
01
Æ-Nest
2D cut-stock optimizer for modular wall panels. Solves a NP-hard bin packing problem using heuristic algorithms with kerf management, rotation and CNC output in DXF.
Python NP-Hard CNC · DXF BIM Integration
02
CargoCast
Pre-shipment container planning tool. Takes SKU codes and estimated quantities, simulates 3D loading and outputs how many containers a shipment needs — before the packing list exists.
Python · FastAPI 3D Bin Packing Web UI
03
LoadScan
Operational logistics tool for real packing lists. Computes 2D footprint and 3D volume occupancy per container with stacking rules, weight constraints and graphical layout output.
Python · JS 3D Visualization Logistics
04
Door Pack Optimizer
Automatically configures shipping crates for technical hospital doors — hermetic, lead-lined, acoustic — decoding product strings, estimating weight, and solving a multi-constraint bin packing problem.
Python Multi-constraint Packing DSS
05
Gantt PM
Automatic production scheduling system. Transforms technical order data into a Gantt-based plan, allocating activities across resources and timelines with fast recalculation on change.
Excel · VBA Scheduling Production
06
ContactBase XL
Data governance system for an 85,000+ record B2B contact database. Deduplication, normalisation, validation rules, structured CRUD forms and automated email drafting via Outlook integration.
Excel · VBA Data Quality 85k Records
07
RAG Experiments
Exploratory work on local LLM inference and Retrieval-Augmented Generation architectures for querying technical documentation — product specs, manuals, project records — without leaking data externally.
Python LLM · RAG Local Inference
08
Micro Tools & Analytics
A set of focused utilities: MBOX-to-PDF batch converter, statistical production and supplier analysis scripts, and data pipeline helpers that turn raw ERP exports into structured decision-support outputs.
Python Automation Analytics
Degree Thesis · 2026
Digitalizzazione e automazione dei processi
in un'azienda del settore healthcare

My thesis documents the complete methodology and technical implementation behind the tools above — from process analysis and criticality mapping, to heuristic algorithm design, to AI/RAG experimentation and the ÆMed vision. Written from 12 months of embedded work in a real industrial environment.
