About Me — Senior Full-Stack Software Engineer

I’m a Senior Full-Stack Software Engineer with 12+ years of experience building enterprise-grade applications, scalable microservices, and AI-powered automation systems.

I specialize in Java 17, Spring Boot, REST APIs, cloud-native architecture, AWS, Azure, NodeJS, React, and event-driven systems.

My work includes designing secure backend platforms, optimizing distributed systems, and building LLM-driven workflows for intelligent document processing and automation.

I also enjoy writing clean tutorials to help developers learn Java, Spring Boot, AI, and backend engineering step by step.

Developing With a Passion While Exploring The World.

I’m passionate about building high-quality software that follows well-established software engineering principles and modern architectural best practices. I believe great systems come from great foundations — not shortcuts.

I design applications using proven engineering principles such as SOLID, DRY, KISS, clean architecture, and domain-driven thinking. I enjoy applying enterprise-ready patterns like dependency injection, layered architecture, repository pattern, service orchestration, and event-driven workflows to create robust, scalable systems.

I strongly value writing Clean Code and following ideas from Effective Java — clarity, correctness, immutability, safe API design, and defensive programming. My goal is always to build code that is easy to maintain, extend, and reason about.

I consistently follow industry standards, whether it’s REST API best practices, cloud-native design guidelines, microservice principles, logging & tracing standards, DevOps conventions, or secure coding practices. I want every project I work on to be production-ready, scalable, and future-proof.

Beyond engineering, I’m always exploring new technologies, learning modern tools, improving my craft, and sharing insights through tutorials. Code & Candles is my space to teach developers Java, Spring Boot, backend engineering, and AI — with a focus on real-world, practical examples.
