Message

At TÜRMOB, I lead the three-person team responsible for LUCA’s tax declaration service. I built its Java 17 and Spring Boot 3 microservice, which went live in 2025 and processes more than 200,000 declarations on peak filing days.

I’ve also modernized legacy Java systems and developed asynchronous services, observability, and LLM features. At Copetract Yazılım, I migrated PHP modules to Java and Spring Boot and built legal-document tools; earlier, I developed monitoring and production-tracking systems at BMS Savunma Teknolojileri and Milsan Elektronik.
