At Expenzing Nexstep Infotech, I develop enterprise backend modules for a cloud-based spend management platform, supporting procurement and financial workflows through Java, Spring Boot, Spring MVC, Hibernate, and REST APIs.
I've built the core workflows behind Rent Management and Tenant Management systems, including rent vouchers, leases, invoicing, payment tracking, tenant onboarding, lifecycle management, and integrations between backend services.
I automate recurring operations with schedulers for invoice generation, contract renewals, and email reminders. I also build Apache POI Excel bulk uploads for high-volume voucher data, optimize MySQL and Hibernate access for large datasets, and remediate VAPT vulnerabilities.
I've maintained legacy Apache Struts and JSP applications, deployed and supported Java services on WildFly, and resolved production issues. I continue strengthening my Java, data structures, and SQL skills through 100+ LeetCode problems.
