CHAPTER · 04 // ENGINEERING BACKGROUND

Before the AI systems, there was the physical infrastructure.

01OIL & GAS FIELD ENGINEERING

Power Systems, High-Voltage & SCADA Instrumentation

SONATRACH · Equinor · ENI · CEPSA — Algeria · 2023 – 2025

Two engineering internships across joint-venture Oil & Gas sites, working on the electrical backbone of live energy infrastructure.

  • Analyzed Gas Turbine Generators (GTG) and their electrical subsystems
  • Inspected 10kV motor high-voltage protection systems, ran Megger relay testing
  • Supervised DCS and PLC logic across heavy energy infrastructure
  • Maintained UPS units, transformers, and rotating machinery on critical circuits
02PHARMACEUTICAL FACILITIES ENGINEERING

Process Supervision & Facilities Quality Control

Al-Hikmah Pharmaceuticals — Algeria · 2023

Automation and quality-control engineering inside a regulated pharmaceutical production environment.

  • Managed air treatment systems (CTA, chillers, dehumidifiers) to pharmacopeia spec
  • Supervised purified-water stations — reverse osmosis & EDI — via HMI/PLC interfaces
  • Maintained automated production lines (blistering, counting) under strict SOPs
  • Ran physicochemical quality checks (pH, conductivity) against pharmacopeia standards
03ACADEMIC FOUNDATION

MSc Electrical Engineering & Green Hydrogen

ENP Algiers · University of Rostock · 2021 – 2026

Five-year engineering degree plus a specialized green-energy certification — the control-theory foundation everything after it builds on.

  • High-voltage protection schemes, signal processing, automated control theory
  • Simulated hydrogen fuel-cell dynamics in MATLAB/Simulink (static & dynamic behavior, Bode analysis)
  • Studied matrix converters and thermal sensors for offshore wind-to-hydrogen systems
  • Wind Energy & Green Hydrogen certification — University of Rostock (Prof. Uwe Ritschel)
CHAPTER · 05 // ABOUT & RESUME

AI Engineering Philosophy

Mehdi Mechkak

Applied AI Engineer
Paris, France · CET

I specialize in architecting evidence-first artificial intelligence systems. My work focuses on bounded retrieval-augmented generation (RAG), deterministic data engineering, and human-in-the-loop workflow guardrails.

“I build AI systems that show their work. Every answer is grounded in retrievable evidence or the case is escalated — no black boxes, no hallucinated numbers, just accountable AI teams can trust and defend.”
