IGOR DAVINCI

Automation & Commissioning Engineer · Senzani Brevetti S.p.A.

OEM of automatic machines for food packaging. Export above 85%.

• Customer acceptance tests (CAT/SAT) run on my own at sites abroad, with no project manager, covering software, electrical installation, the customer interface and the handling of non-conformities. 100% of the tests passed first time, zero return trips.
• Signing of the validation reports on behalf of the company.
• Commissioning and service in France, Belgium, Czech Republic, United States, Serbia, Romania and China; remote support via Secomea and customer VPN.
• Technical training delivered to customer personnel (2–5 days, in Italian and in English) on software maintenance, electrical engineering and machine operation.
• Redesign of the software architecture of a cartoning machine starting from a legacy base, defining logic, data structure and naming standards on my own.
• Development and refactoring of PLC applications on Siemens S7-1500 in LAD and ST, with modular state-machine architectures for adjustment, handling and format-change stations.
• PLCopen motion control: gearing, superimposed moves, axis managers and phasing; testing of machines with up to 20 controlled axes.
• Functional safety: diagnostics and setup of Pilz PNOZmulti 2 systems and Siemens F-CPU: speed monitoring, SLS functions, PROFIsafe chains and validation parameters.
• Diagnosis of intermittent faults and handling of production stoppages, on site and remotely; development of diagnostic instrumentation for anomalies on vision sensors, quantifying their share of the scrap and locating the cause at firmware level.
• Technical analysis and HMI migration from TP900 Comfort to WinCC Unified, with an assessment of the architectural constraints.

Automation Software Engineer · IPREL Progetti (Gruppo SACMI)

Industrial automation software house of the SACMI Group.

• Led the development of 9 complete PLC projects for SACMI Ceramics, plus smaller orders, on Omron Sysmac Studio and CX-One, the main training platform before moving to Siemens TIA Portal.
• Development of simulation modules for software validation before testing, removing the need for the programmer to be on site during installations; the result held even after I left the company.
• Design of standardised, reusable software modules, cutting development time on later orders.
• Training and mentoring of 2 new colleagues, passing on method and skills.
• Technical support to customers and writing of user manuals for the operation and maintenance of the plants.

Automation Software Engineer, Internship · Senzani Brevetti S.p.A.

• ITS thesis: Development and testing techniques for PLC software: a packaging case (93/100).
• Testing of machines with PackML architecture, robot cells and cam axes; optimisation of Siemens PLC software.

Electrical Design Hardware, Internship · Comecer

• Design of electrical drawings with SPAC Automazione, datasheet study and component selection, technical data management via PDM-AS400.

Ð-Unit Suite · software for industrial automation

Built on my own, outside working hours

• Modular desktop suite for the analysis of TIA Portal projects and EPLAN electrical drawings. Microkernel architecture with manifest contracts: the core does not know the modules by name, and adding a module requires no change to the core.
• Architectural constraints enforced by automated tests, 265 tests across the suite, semantic versioning and cache invalidation on a pipeline change.
• Structured extraction module: accuracy taken from 72% to 100% top-1 on a frozen benchmark set, with verified ground truth.
• Measured operational impact: a verification task that took about two person-days now takes under an hour: over 90% reduction.
• Integration with external systems: SQL Server, SQLite, OPC UA for data acquisition from PLCs, network tooling in PowerShell (PROFINET, S7, ARP scan).
• Stack: Python, JavaScript, Tauri desktop shell (Rust), Git with semantic versioning and a discipline of atomic commits.
