About

Software Developer with 3 years of experience building enterprise systems that solve real business problems. I work with Java Spring Boot backends, React/Next.js frontends, and PostgreSQL databases—delivering end-to-end solutions from architecture to deployment.

At Hisar Intercontinental Hospital, in Aurora Bilişim—its software development unit—I developed and supported a warehouse management platform for enterprise clients, covering the inventory, order and shipment modules. I owned the REST API endpoints and service layers, handled data access with Spring Data JPA, and delivered ERP and CRM integrations with client systems. I set up and ran the CI/CD pipelines, and was responsible for taking developments through test and production.

I also contributed to an R&D project for a hospital medication-dispensing and stock-tracking system, building the integration layer that fed drug-consumption data into the hospital information system.

My background in IT infrastructure and test automation (Selenium, Postman) gives me strong debugging instincts and a quality-first mindset. I work well in agile teams and take ownership of problems from root cause to production fix.
