🎓 BE Computer Science & Data Science — AMC Engineering College 💼 Software Engineering Trainee @ Vonage (Part of Ericsson) 📍 Bengaluru, India

I'm a Backend Developer with 1 year of hands-on experience building and testing backend services, REST APIs, and automation solutions.

At Vonage (Part of Ericsson), I worked on telecom billing systems, contributing to API development, validation frameworks, test automation, and production issue resolution across high-volume services.

I enjoy designing clean, scalable backend systems, solving engineering problems, and building reliable APIs with strong testing practices.

Bengaluru, India · Jun 2025 – Jun 2026

• Developed and enhanced backend REST APIs using Java 20 and Spring Boot, implementing validation frameworks and business logic improvements that reduced API failures by 10–15%.
• Engineered cross-currency and network validation logic for telecom billing workflows, improving data integrity and preventing cost-processing errors.
• Resolved 5+ production issues across cost synchronization, Partner CDR processing, and RCS upload workflows, while standardizing structured error handling to reduce debugging time by 15%.
• Architected and parallelized PyTest API regression testing, reducing execution time by 75% (2 hours → 30 minutes) while expanding coverage across 50+ edge cases.
