Message

At Aktech A.Ş., I deliver .NET 8 microservices for Tosla İşim, orchestrating 7,000–8,000 daily transactions across payment channels while keeping p99 response times within SLA. I also opened two payment channels by integrating Android POS and Fiscal POS hardware with third-party payment providers.

At Toucan CodeLabs, I was the primary engineer on an enterprise standards platform for the Turkish Standards Institute. The event-driven platform automated standards publishing, compressing work that took days into seconds.

I’ve worked on idempotent integrations, auditable transactional data models, and CI/CD delivery. At Aktech, I introduced SLA-driven event logging and distributed transaction tracking, and I contribute to architectural decisions and code reviews.

Earlier, I built Java and Spring Boot systems during internships and worked part-time in DevOps at Jotform, where I replaced manual server setup with Ansible Infrastructure as Code. My projects include a .NET 8 payment orchestration service and a Java 21 standards ingestion pipeline.
