20+ years Critical systems

I design and build high-performance software products and electronic systems, transforming complex problems into robust and maintainable solutions. In recent years, I have consolidated a hands-on approach to AI and Deep Learning: training models (PyTorch), exporting them to ONNX, and deploying them on web and .NET platforms for efficient inference, including real-time scenarios.

High-Complexity Developments

Steamly - Steam Boiler Simulator

Windows-based dynamic steam boiler simulator that replicates the real transient behavior of an industrial unit using first-principles mass & energy balances and IAPWS-IF97 thermodynamics. Models the complete boiler train: furnace/combustion, steam drum, superheater, economizer, air preheater, and stack losses, enabling realistic start-ups, load ramps, and upset scenarios. Includes PID control loops for key variables (pressure/level/blowdown) to support control tuning and operator training in a safe, risk-free environment.

Industrial Simulation
Falcon 9 Simulator

Real-time Falcon 9 first-stage simulator built on engineering equations, with full telemetry live on-screen (speed, altitude, linear/angular accelerations, thrust, fuel flow/consumption, aerodynamic and structural loads, and spatial positioning). Includes a 3D OpenGL view plus optional synchronized real-flight video for accuracy comparison. Fully parameterizable structure and engines (masses/CG, aero parameters, thrust and Isp at sea level vs. vacuum), with user-drawn curves for throttle modulation and vehicle attitude, plus MECO and stage-separation triggers. Exports an Excel/CSV flight log with 18 parameters sampled every 25 ms (40 Hz) for post-analysis.

Aerospace Simulation / 3D
AEA - Atmospheric Electrical Activity Monitor

Long-range atmospheric electrical activity detection, monitoring, logging, and alerting system designed to provide early warning of lightning risk for outdoor operations, telecom/power infrastructure, and transportation. Uses dual omnidirectional ELF RF antennas on a 2.5 m detection tower and high-speed digitization up to 10,000 detections/s (5,000 per channel). Data is backhauled via an isolated 2.5 GHz ISM microwave link (optional RS-422) to a Windows monitoring station that visualizes events in real time, counts minor/major activity over 24 hours, stores data locally and in a remote Internet database, and replicates monitoring to remote terminals via TCP broadcasting (typical end-to-end delay < 1 s).

Storm Monitoring & Alerts
PMFC - Pyro Musical Fireworks Center

Professional pyromusical show-control platform that synchronizes fireworks firing cues to music with <5 ms timing accuracy. Modular USB architecture delivers 144 outputs per interface (6x24 passive terminal blocks) and scales up to 10 interfaces per PC for 1,440 independent channels. Supports continuity testing, backup show sequencing, and manual override; high-speed firing up to 40 channels/s (up to 100 initiators in series per channel). Includes the industry's first 3D OpenGL music-synced fireworks simulator.
