Backend Developer · 4th Year Computer Engineering Student
Ankara, Turkey

I build performance-focused, scalable backend services.
Mostly working with Java (Spring Boot), distributed systems, and async messaging.
I package whatever I build with Docker and get it running on my own.

• High-concurrency architecture built entirely with Spring Boot for scalable core business logic.
• Distributed locking via Redis (Redisson) to prevent race conditions (no double-booking).
• Asynchronous email notifications through RabbitMQ.
• Observability with Prometheus & Grafana (JVM, CPU, memory), fully containerized with Docker.

• FastAPI + PostgreSQL, with a spaced repetition algorithm tailoring learning cycles.
• LLM integration to auto-generate questions from uploaded PDFs.
• High-concurrency RESTful APIs, Docker-based deployment.

• Spring Boot, JWT authentication, role-based access control (RBAC), multi-tenant design.
• Responsive UI with Bootstrap, CI/CD via GitHub Actions.
• Collaborative development with Git branching strategies.

• İnfodif (Embedded Software Intern) – TCP/IP SCPI commands, high-frequency JSON stream parsing, hardware-software feedback loop.
• Bozok University – Modernized administrative workflows with Spring Boot.
• Ultrasonar (Freelance Backend Dev) – Maintained and extended Spring Boot backend for industrial machine software.
• Google DSC (Web Dev Lead) – Django backend, introduced clean code & mandatory code reviews for a 10+ dev team.
• Moonmach – Built a real-time Spring Boot control panel for solar-powered cleaning robots.

Bozok University – B.Sc. Computer Engineering (Oct 2023 – Present)
GPA: 3.19/4.00

• Hacktrick Cybersecurity Conference (BTK, 2024) – Reverse engineering, software analysis, system security.
