This is what I do

💼 Kayis Rahman – Resume

Welcome! I’m Kayis Rahman, a Software Engineer, Cloud Enthusiast, and Tech Leader with a passion for crafting clean code, scalable systems, and beautiful backend architecture. With over 9 years of professional experience, I’ve delivered high-impact solutions across diverse domains.

🧑‍💻 About Me

I’m a backend-focused developer currently based in Dublin, Ireland, with a solid foundation in Java, Spring Boot, and microservices architecture. My professional journey has taken me through exciting challenges—leading engineering teams, deploying Kubernetes clusters, automating CI/CD pipelines, and optimizing performance in cloud-native applications.

I’m driven by curiosity and a love for problem-solving. Whether it’s redesigning a legacy email system to slash costs and boost performance or mentoring junior developers over coffee, I always aim for solutions that balance practicality and elegance.

💡 Current Focus:

  • Backend Engineering (Java, Spring Boot)
  • Cloud Platforms (AWS, Google Cloud)
  • DevOps & Automation (Docker, Kubernetes, GitLab CI)
  • Microservices & Scalable Architecture

📌 Goal: Open to remote, freelance, or part-time roles — especially ones in Java and Cloud technologies where I can make a real impact.
