Mert Kazım İşler
Senior Software Developer
Summary
Backend-focused software developer with 7+ years building B2B products: customer-engagement integrations at Insider, the hr-Xsoft HR platform at Obtolab, and custom ERP/CRM systems for textile and logistics clients.
Specialized in PHP (Laravel), REST APIs and third-party integrations, with frontend work in React and Vue.js. I’m at my best when handed an unfamiliar system: I learn how it works, find what’s broken and ship the fix.
