At Walmart Global Technology, I worked on the Wireless ESP platform supporting carrier activation across retail and online channels. I resolved production issues across distributed services and helped restore priority-slot booking in the appointment flow.
I contributed to a company-wide CPU capacity optimization initiative, improving resource utilization from 3% to 38% and reducing annual infrastructure spend by $700K through automation and telemetry-driven capacity planning.
I also improved React Native checkout performance by optimizing rendering and API calls, reducing checkout rendering time by 40%. At EPAM Systems, I developed Java and Spring Boot microservices for a ticket-monitoring platform and helped reduce a data extraction tool’s execution time by 80%.
My work spans Java, Spring Boot, distributed systems, and cloud-native services, alongside frontend development with React and Angular. I’ve also contributed to technical design documentation, code reviews, and mentoring through pairing and design discussions.
