Overview

Quality Assurance Engineer and Certified Scrum Master with 12 years of experience in the Quick Service Restaurant (QSR) industry, including 8 years in QA and 4 years in technical support. I specialized in testing cloud-based B2B SaaS payment processing and POS systems serving 10,000+ restaurant locations globally. Started at an established family-owned business, retained through a private-equity acquisition, and subsequently acquired by publicly traded Global Payments, demonstrating adaptability across diverse organizational structures and business models. Strong background in test strategy, SQL data validation, API testing with Postman, and maintaining automated test suites. Used Kibana logs to identify kiosk API failures, then implemented targeted test cases to improve order completion reliability from 78% to 99.9% over 4 months. Reduced post-release hotfixes by 75% by advocating for monthly release cycles instead of bi-weekly, allowing adequate time for thorough testing.

Quality Assurance Engineer III
May 2021 – September 2023

Served as Scrum Master, facilitating sprint planning, daily standups, retrospectives, and release planning. Collaborated with the Director of Engineering to define the product roadmap, prioritize backlog, and select features for development. Acted as liaison between QA team and leadership. Led comprehensive testing for PayPal payment integration, including transaction flows, refunds, and reconciliation across web and mobile platforms. Analyzed customer support call volume trends and identified root causes of the top 5 recurring issues, working with the development team to implement permanent solutions. Defined acceptance criteria for user stories, documented product roadmap and release plans in Confluence, and facilitated backlog grooming sessions.

Key Accomplishments
  • Reduced customer support call volume by 40% over the course of a year through systematic root cause analysis, identifying bugs masked by quick-fix restarts and working with the development team to implement permanent solutions.
  • Used Kibana logs to identify kiosk API failures, then implemented targeted test cases to improve order completion reliability from 78% to 99.9% over 4 months.

Quality Assurance Engineer II
March 2019 – May 2021

Led integration testing for third-party payment systems and delivery platforms. Retained through Global Payments acquisition, October 2018. Tested Verifone and Ingenico payment devices, validating transaction processing, refunds, and device communication protocols. Tested kiosk systems using XML injection via telnet to validate order flow. Established delivery partner integrations (DoorDash, GrubHub, UberEats) using Postman to test JSON-to-XML transformations through the Omni integration layer. Executed comprehensive testing for loyalty program implementations. Tested database migrations from MySQL to MariaDB during OS2 to OS4 system upgrades.

Key Accomplishments
  • Identified and resolved a critical defect in delivery order processing where orders were getting stuck in an intermediate state, causing orders to loop between terminals. Diagnosed root cause through exploratory testing within one week after a month-long escalation, and implemented the fix within 3 days. The issue resulted in estimated tens of thousands of dollars in lost revenue per affected restaurant location.
  • Discovered that the developer's loyalty system implementation created 1:many relationships instead of the specified 1:1, advocating for retention of this enhancement, which enabled multiple concurrent loyalty providers and significantly expanded product capabilities.
  • Accelerated loyalty program development from an 8-month timeline to 2 months by identifying the existing dynamic list rules feature that could be leveraged for implementation.
