# Alizahi > Mechanical and hardware engineering case studies. ## Pages - [Project 8](https://alizahi.com/project-8/): Final case study summary covering the validation records, drawing sets, and FEA reports available for inspection, and the direct channels for mechanical and hardware engineering evaluations. - [Project 7](https://alizahi.com/project-7/): Engineering domain: mechanical design and prototype validation. Timeline: prototype test cycle. Role: lead design engineer. - [Project 6](https://alizahi.com/project-6/): Engineering domain: Mechanical and hardware engineering. Timeline: [project dates]. Role: Design, fabrication, and verification lead. - [Project 5](https://alizahi.com/project-5/): Engineering domain: Mechanical and hardware systems. Timeline: iterative prototype test cycles. Role: lead engineer, diagnostics and redesign. - [Project 4](https://alizahi.com/project-4/): Parametric models set the geometry and tolerances, and the shop process was built to hold them. - [Project 3](https://alizahi.com/project-3/): First-principles free body diagrams resolved peak bending and shear forces at each load-bearing member before any geometry was committed. - [Project 2](https://alizahi.com/project-2/): Engineering domain: Mechanical and structural design. Timeline: to be confirmed. Role: Lead engineer. - [Project 1](https://alizahi.com/): The root-cause problem is described here: the failure mode or design gap that motivated the project, stated in measurable terms. - [Home](https://alizahi.com/home/): Led the design and 4-axis Okuma CNC machining of precision locating fixtures for the 2027 vehicle to control thermal weld distortion and hold tight suspension hardpoint tolerances.
