Ali Çınar Aslan | Automotive Technical Portfolio
A technical portfolio built around automotive technology, vehicle restoration, and mechanical and electrical work. This platform documents fault diagnosis, periodic maintenance, technical surface treatments, parts compatibility analysis, and hands-on workshop practice.
The main focus is the OEM+ restoration, electrical repair, and technical renewal of a 2004 Volkswagen Golf Mk IV (1.6 8V BFQ, Pacific).
My Technical Journey
I was born in Manisa on 23 August 2005. I completed my primary and secondary education in Balıkesir and Antalya and graduated from Abidin Pak-Pakmaya Anatolian High School in 2023. After undergraduate studies in different disciplines, I redirected my career focus toward mechanics and automotive electronics and transferred to Kocaeli University. I am currently continuing my studies in the Automotive Technology program at Kocaeli University Ford Otosan İhsaniye Automotive Vocational School.
In my work, I focus on passenger-car mechanical repair, periodic maintenance, OEM-standard parts renewal, electrical fault finding, and vehicle diagnostics. I support the practical experience I gain in the workshop with technical service documentation and diagnostic tools, and I develop my skills in root cause analysis of faults.
My main goal is to combine the discipline of mechanical repair with electronics and diagnostics, and to become a competent specialist working to international standards in automotive mechatronics and technical service processes.
