QA Engineer · Manual + Automation
Muhammed
Yıldız.
Manual judgment, automated at scale.
I believe great QA is manual and automation together — exploratory instinct paired with frameworks that scale. 5+ years helping teams ship with confidence across e‑commerce, CRM and AI platforms.
Available for freelance & consulting — remote, worldwide
Test engineer since 2021. My approach has always been the same: manual testing and automation belong together — sharp human judgment, backed by automation that scales. I ship fast and safely, and I build my own products end‑to‑end.
I also run Prime Picks — a small studio for the apps I design and ship.
