Senior Software Engineer at WI SOLUTIONS LIMITED who cut service response time from 1.8 seconds to 420 milliseconds.

At WI SOLUTIONS LIMITED, I owned technical delivery and backend architecture for enterprise web applications using C#, ASP.NET Core, and REST APIs. I optimized service communication and resource-intensive operations, reducing response time from 1.8 seconds to 420 milliseconds.

I also improved production reliability through logging, monitoring, and troubleshooting, reducing recurring application defects by 32%. I mentored four engineers and coordinated implementation with PM, Design, QA, and DevOps.

Earlier, at Electronic Arts, Arnia Software, and Caphyon, I developed enterprise applications, APIs, and integrations. My work included query optimizations, automated testing, and RabbitMQ messaging, with measurable improvements to application performance and regression defects.
