What I'm looking for

I’m actively targeting backend and microservices roles where I can design end-to-end Spring Boot systems, build reliable REST APIs, optimize performance, and deliver business-critical features in a secure, scalable environment.

I’m a Senior Java Backend Developer with 3+ years of experience building scalable, secure, and high-performance backend systems. I specialize in Spring Boot and microservices architecture, with strong expertise in REST APIs, JPA/Hibernate, and enterprise-grade development.

At Money Tree Realty Pvt. Ltd., I architected and developed backend services for enterprise CRM systems, designing microservices for lead generation, costing logic, reporting, and approval workflows. I also implemented large Excel upload processing with Multi threading and batch optimization, significantly reducing processing time, while building automated email and Excel reporting pipelines.

I’ve delivered secure and maintainable backend modules across teams and projects, including Spring MVC and PostgreSQL development at Velocis Systems Pvt. Ltd. and scalable Spring Boot REST APIs with optimized persistence layers at Vartulz Technologies, consistently aligning components with microservices principles.
