I’m Vivek Saini, a passionate software developer, educator, and content creator. With a strong background in Java, Spring Boot, and system design, I help developers level up their coding skills through clear tutorials, hands-on examples, and real-world insights.
Whether it’s building scalable backend solutions or breaking down DSA problems, I believe in learning by doing and sharing that journey with others. I’ve also created VivekSainiCodes.com and a YouTube channel to mentor aspiring coders, share interview strategies, and bring simplicity to complex tech concepts.
When I’m not coding or mentoring, you’ll find me exploring new frameworks, engaging with developer communities, and building tools that make learning enjoyable and effective.
