Junior Java Developer

Feb 2024 – Present · 2 yrs 1 mo · Kozhikode, Kerala, India · On-site

As a Back-End Developer, I have been working on financial technology solutions, optimizing legacy systems, and building efficient backend applications.
Key Contributions:
✅ Worked on a 30-year-old legacy project (Customer Portal):
Maintained and enhanced a mainframe-based application originally built using Java, where even the frontend was written in Java.
Adapted to working with minimal built-in functions, gaining a deep understanding of low-level Java implementations.
✅ Developed DCC Currency Conversion API:
Built a backend service to handle currency conversion for multiple international transactions, integrating it into the existing Customer Portal system.
Designed efficient database queries to retrieve real-time conversion rates, improving accuracy in financial settlements.
✅ Backend Development for PineOne (OneApp) – 10 months:
Led the backend implementation of a web application for merchants to track their transactions.
Designed and implemented 30+ API endpoints, ensuring high performance and scalability.
✅ Critical Production Fix & Performance Optimization:
Identified and fixed a last-minute critical bug the day before production deployment, ensuring a smooth release across SIT and UAT environments.
Optimized database query execution, reducing API response time from 5 seconds to under 1 second.
This change significantly improved user experience, reduced server load, and cut Oracle DB costs for the company.
