Senior Java Backend Developer building telecom transaction services at TimweTech.

United Arab Emirates

Message

At TimweTech, I designed and delivered Java and Spring Boot backend services for telecom transaction flows. They sustained peak loads without degrading SLA performance, and I standardized REST API contracts for internal and third-party clients.

I also streamlined Jenkins and Docker CI/CD pipelines and addressed production performance bottlenecks through profiling, query optimization, and targeted refactoring.

At VMware, I built a reusable Java and TestNG automation framework and shared libraries adopted across three product teams. Earlier, at Infosys, I migrated legacy modules to Spring Boot microservices; across my prior roles, I also developed a scheduled payroll correction job for a Goldman Sachs application.
