About Saba
PhD-level power electronics and railway systems engineer with 8+ years of industrial experience in the rail transportation sector (Alstom).
I provide short, high-impact technical consulting missions focused on:
• Power electronics systems (converters, inverters, capacitors)
• Hybrid and railway traction systems
• Simulation, modeling, and validation using MATLAB/Simulink
• Design review, troubleshooting, and feasibility studies
My experience includes system renovation projects, end-of-life component assessment (overhaul vs replacement decisions), capacitor refurbishment programs, and technical reporting for industrial and research projects.
I also support engineering teams and researchers with technical documentation, simulation validation, and academic paper review.
I am available for short missions (1–10 hours) with clear deliverables and fast response.
