What I'm looking for

I seek a hands-on developer role focusing on Java backend or Android work, collaborative teams, mentorship, and opportunities to build scalable API-driven systems.

I am a Java developer with hands-on experience building backend systems, REST APIs, and Android integrations. I bring strong problem-solving skills and a habit of learning new technologies quickly.

During a Java Development internship at SORT SOLUTION, I helped develop a courier tracking and management system with parcel management, real-time tracking, and user authentication, integrating Java applications with MySQL and participating in code reviews and Agile workflows.

I have built collaborative projects such as Smart Salon (Spring Boot REST APIs) and Raksha (Android app with Java, XML, and MySQL), contributing to backend development, database design, and service integration to ensure smooth communication between apps and servers.

I have also demonstrated algorithmic aptitude—solving 300+ problems on GeeksForGeeks and LeetCode, earning a 5 Star Java badge and a 4 Star SQL badge on HackerRank—and I actively seek roles where I can ship reliable backend services and grow as an engineer.
