At Amdocs, I develop and maintain Spring Boot microservices and REST APIs for a transaction-processing platform handling 10M+ transactions per day. I’ve delivered 50+ production changes with a 100% success rate.
I migrated 20M+ subscriber records from an offline to an online charging platform with zero data loss, using multithreaded batch processing and JDBC batch writes. I also created Oracle reconciliation scripts to validate data integrity after each migration run.
At Amdocs, I upgraded Oracle from 11g to 19c and migrated production applications from 32-bit to 64-bit Linux servers. I’ve also optimized Oracle queries, reducing batch and report runtimes by up to 50%.
In personal projects, I built an inventory and activation REST service with Spring Boot and a codebase analysis platform that indexed 10,000+ files and provided sub-100 ms lookup.
