About
Mechanical Engineer with hands-on experience in subsea robotics and product design. I help startups and companies turn ideas into working prototypes — from concept sketches and CAD modeling to functional, ready-to-manufacture parts. I own my own 3D printing setup, so I handle everything in-house: design, iteration, and physical prototype delivery, with official invoicing available for businesses. Comfortable working with SolidWorks for mechanical design, tolerancing, and design-for-manufacturing. Based in Tunisia, working with clients locally and internationally.

Experience
- Mechanical Engineer Mare Custos · Full-time Apr 2025 – Present 1 yrs 5 mos Tunisia Design pressure-resistant subsea enclosures rated for 50–300m water depth (material selection, wall-thickness sizing, sealing concept, FEA validation). Build complex subsea systems from scratch — full cycle from design to physical testing. Perform static structural FEA to evaluate stress, deformation, and safety factors under hydrostatic loading. Design for CNC manufacturing of complex manifolds, with a focus on cost-effective, safety-compliant value engineering.
- Mechanical Engineering Intern (End of Study Project) MARE CUSTOS · Internship Feb 2024 – Jul 2024 5 mos Tunisia Designed an unmanned surface vehicle (USV) for ROV deployment and transport. Developed mechanical architecture and ran structural simulations to validate the design. Calculated energy requirements for the ROV/USV mission and sized a photovoltaic system for autonomous power.
- Mechanical Engineering Intern DRÄXLMAIER Group · Internship Jul 2023 – Aug 2023 1 mos Tunisia Analyzed a mechanical need for a twisting cable machine, evaluated design options for technical/economic viability, and created detailed plans and blueprints using SolidWorks.
Education
