Portrait of Buğra Çetinkaya

Foundations before trends.

I'm a computer engineering student and software developer who cares more about foundations than trends. I build scalable backends, design purposeful mobile experiences, and explore AI as a practical tool rather than a buzzword.

I value clean architecture, disciplined code, and products that endure beyond their first release.

plan, hustle, prove.

Redis Is More Than Just a Cache

Redis is more than a cache: its data structures support rate limits, transient messaging, streams, leaderboards, and carefully designed job scheduling.
