About

Building bridges between technical excellence and business impact

My Journey

Started as a developer passionate about clean code and scalable systems. Evolved into a team leader who mentors others while staying hands-on with cutting-edge technologies. I believe the best solutions emerge when technical expertise meets deep empathy for users and teammates.

Currently leading engineering efforts at Codefirst, where I guide cross-functional teams in delivering enterprise-grade solutions for clients like Turkish Airlines.

Performance First

Every line of code and architectural decision is evaluated through the lens of scalability and user experience.

Quality Driven

Comprehensive testing, code reviews, and monitoring ensure reliable systems that teams can confidently build upon.

People Focused

Technology serves people. Great software comes from diverse, empowered teams who feel supported and challenged.
