Project: Notify, Bank Scoring (aka "Tabby Cash")

As a Software QA Engineer (Consult), I improved the reliability and scalability of Tabby’s core services by driving functional and load testing, enhancing automation, and increasing test visibility through documentation and monitoring.

• Performed functional and load testing across the Notification domain, ensuring the stability of user messaging across multiple channels (email, SMS, push, WhatsApp).
• Designed and ran load tests for Notify Service gRPC handlers, created Datadog dashboards, and documented architecture and results in Notion.
• Developed test cases for Transfer service and financial products like Card Transactions, P2P, Local Transfers, and Top-Ups.
• Implemented and optimized automation for TSS UI; initiated automation for ScoreDomain Ops, enabling scalable regression testing.
• Analyzed and improved Notify UI functionality, identified gaps, and defined improvement scope.
• Completed Coursera Golang specialization — enabling contributions to test automation and code review.
• Shared QA docs, load testing guides, and dashboards to enhance visibility and cross-team collaboration.
• Automated user creation for Antifraud (OTL + Monthly Billing) via Bash, cutting manual effort and speeding QA cycles.

Key outcomes:

• Laid groundwork for scalable test automation in Tabby Cash and Notification services.
• Increased reliability and maintainability of load testing with dashboards and structured docs.
• Reduced manual testing and boosted team velocity via Risk Restriction workflow automation.
