Welcome to Learning Notes
Hello, I'm Vinay Kumar K.
I’m a software architect and engineer with 18+ years of experience building scalable, cloud-first solutions using Java, Spring Boot, and AWS.
My work spans enterprise systems, cloud contact center platforms (Voice, SMS, Email, WhatsApp), and performance engineering for high-availability services.
This site is my public space for continuous learning.
I organize and share technical concepts, best practices, and architectures across software, cloud, and modernization. My notes capture core ideas, hands-on lessons, and real-world insights.
Here, you'll find focused insights from:
- Cloud and AWS deep-dives
- Java/Spring fundamentals and patterns
- Architectural principles and reference systems
- DevOps, productivity tools, and daily engineering learnings
I strive to validate and update regularly. Please cross-check critical topics with official documentation and trusted sources.
