Open to new opportunities

Building reliable, high-performance backend systems for real-world products.

I am Ümit Can Yücel, a hands-on backend developer building scalable and high-performance systems with PHP (Laravel, CodeIgniter), MySQL, PostgreSQL, and cloud infrastructure. I focus on production-ready APIs, system reliability, and practical solutions that work under real-world load.

About

With strong hands-on experience in backend development, I focus on building scalable, reliable, and cost-efficient systems using PHP frameworks such as Laravel and CodeIgniter. I’ve worked extensively with cloud environments, backend architecture, and relational databases like MySQL and PostgreSQL, with a strong focus on performance, optimization, and efficient data handling.

I specialize in building and maintaining APIs and backend systems with a strong focus on performance, stability, and long-term maintainability. My approach is hands-on and proactive — identifying potential issues early, understanding system behavior in real-world conditions, and applying practical, reliable solutions. A significant part of my work involves debugging complex issues, optimizing system performance, and ensuring services run efficiently under real production constraints. Alongside my technical work, I’ve also contributed to team collaboration and technical discussions, which has helped me improve communication, knowledge sharing, and mentoring in development environments.
