👨‍💻 About Me

Hi, I'm Onur Yerlikaya. As a CTO, I bridge the gap between complex business requirements and scalable technical solutions. I am passionate about hands-on software development, designing distributed systems, and leading engineering teams to success.

  • 🔭 I'm currently working on High-scale Microservice Architectures
  • 🌱 I'm currently exploring Advanced Kubernetes Patterns & AI Integration
  • 💬 Ask me about Java, Go, Cloud Architecture, and DevOps Strategy

🧭 Engineering Philosophy

🏗️  Architecture First    →  Every good system starts with a solid blueprint before a single line of code.
⚡  Simplicity Wins        →  The best solution is the one your team can understand at 3 AM.
📐  Measure, Don't Guess   →  Data-driven decisions over gut feelings — observability is non-negotiable.
🤝  Teams > Individuals    →  A CTO's real output is the team's velocity, not their own commits.
🔄  Iterate Relentlessly   →  Ship fast, learn faster. Perfect is the enemy of production.
