Ömürcan Özcan

PROFILE / ISTANBUL, TÜRKIYE

Software that survives
the real world.

I’m Ömürcan, a backend-oriented engineer working where business rules, data, people and existing systems meet.

My full-stack experience includes JavaScript and React interfaces, dashboard modules and payment workflows. That application work informs how I design APIs, access control and reporting for operational use.
