Manas ranjan

I am a professional Java Developer with 4+ years of real-time industry experience, currently working at Landmark Group, one of the largest retail organizations in the Middle East & India.
I have worked on enterprise-level web applications for major retail brands such as MAX Lifestyle, Home Centre, Easybuy, Spar, and Funcity, where I am responsible for designing, developing, and maintaining scalable backend systems.
My expertise lies in Java backend development, especially using Spring and Spring Boot microservices architecture. I have strong hands-on experience in building RESTful web services, implementing secure authentication and authorization using Spring Security and OAuth2, and working with databases using JDBC and Spring Data JPA.
In addition to traditional backend development, I also have experience integrating AI/LLM capabilities using Ollama and Spring AI into real-world applications, which helps students understand modern industry trends.
