About DevTech Insights
DevTech Insights is a technical blog focused on Java, Spring Boot, AI integration, system design, and DevOps — written by a practicing backend engineer for engineers who ship.
Who I Am
Hi, I’m the author behind DevTech Insights. I’ve been building backend systems with Java for over 16 years — from early Spring MVC monoliths to Spring Boot 3 microservices running in production at scale. These days most of my time goes to Spring Boot, Java 21, AI/LLM integration, and distributed system design.
I started this blog because too much technical writing online is either too shallow (“here’s how to call an API”) or too academic to apply. I wanted a place to keep the kind of practical, production-ready notes I wish I’d had — the stuff you can actually use on Monday morning.
What You’ll Find Here
- Java & Spring Boot — Deep dives into Spring Boot 3, Java 21+, performance tuning, and production best practices
- AI & LLM Integration — Practical guides on building AI-powered applications, RAG, vector databases, and Spring AI
- System Design — Architecture patterns, microservices, event-driven systems, and distributed systems fundamentals
- DevOps & Cloud — CI/CD pipelines, containerization, Kubernetes, and infrastructure as code
- Performance — JVM tuning, database optimization, caching strategies, and profiling
Why This Blog
Most technical content is either too shallow (“how to use an API”) or too academic (“let’s prove a theorem”). This blog aims for the sweet spot in between — practical, production-ready knowledge that you can apply on Monday morning.
