· Conducted performance testing on serverless stacks within Kubernetes clusters hosted on GCP for Bell Canada

· Helped with performance Capacity management for Black Friday volumes with the new migrated microservices in Kubernetes serverless stack.

· Tested native mobile applications using- tools such as (Loadrunner Truclient, Micro Focus Mobile Center, Appium Android studio and iOS Network traffic analyzer

· Prevented millions of extra requests being called in production due to various bottlenecks with coding.

· Oversaw production monitoring for Android and iOS native applications using Dynatrace and supported multiple successful production releases along with post release activities. For Web applications used Dynatrace Grail for creating dashboards for production monitoring of K8s containers and few other services using DQL.

· Conducted API testing using Postman and Service virtualization with TSV tool.

· Tested web applications on hybrid architecture of monolithic and modern Serverless stacks for various projects and scalability and endurance to sustain Black Friday traffic volumes.

· Black Friday readiness testing via combined testing of native and web applications with various loads and system tuning for optimized performance and reliability.

· Helped create a CI/CD with Dynatrace logs to local Grafana timeseries.

· Utilized Google Dev Tools and Lighthouse audits to diagnose and optimize front-end of various Bell Canada websites and mobile apps (myBell, Virgin Plus, Lucky).
