PROFESSIONAL SUMMARY

I'm a Java Full Stack Developer with 3+ years of hands-on experience building scalable, high-performance web applications in both IT and banking domains. I specialize in using Java, Spring Boot, Angular, and React to create robust full-stack solutions, and I'm well-versed in RESTful APIs and microservices. I've worked in Agile teams where I’ve taken ownership of everything from writing clean backend logic to designing sleek, responsive frontends. Along the way, I’ve gained solid exposure to DevOps practices, CI/CD pipelines, and cloud platforms like AWS and Azure. I enjoy solving real-world problems with clean code, collaborative teamwork, and a focus on quality. TECHNICAL SKILLS
