  • 🔭 Currently building with Spring Boot, Angular, and AWS cloud services
  • ☁️ Experienced with Amazon Connect for cloud contact center solutions
  • 🐳 Passionate about containerization, observability, and DevOps culture
  • 🌱 Always learning — currently deepening expertise in Linux internals and CI/CD automation
  • 💡 I believe great software is equal parts engineering and craft
