1. Senior Software Quality Engineer

   IFS Copperleaf

   sept. 2024 to juin 2026

   • Performed end-to-end quality engineering for enterprise applications supporting integration and extension development on the Copperleaf C55 platform - a .NET-based enterprise SaaS application deployed on AWS - ensuring data integrity, reliability, and release readiness across client-specific workflows and multiple agile teams. • Provisioned and managed QA environments on AWS EC2 Windows Server instances - importing Oracle DB dumps, installing and configuring the C55 suite, and resolving IIS, Oracle compatibility issues. Reduced environment setup from days to hours; used Docker to run containerized QA instances of C55 and Impala SQL for integration testing. • Designed and executed API integration testing using Postman across SAP, RabbitMQ, MuleSoft, Amazon S3, and SFTP integrations, while querying Oracle databases to validate application data integrity and resolving environment configuration issues. • Investigated performance degradation in data export integrations by monitoring server resources and analyzing code with AI-assisted tools (Cursor), producing targeted optimization recommendations. • Tested bulk data loaders (CSV, XLSX) for client data import/export; validated end-to-end data integrity across staging SQL databases (Oracle and MS SQL Server) and custom Excel/Word reports submitted to government authorities. • Participated in spec reviews prior to development to provide testability feedback and identify edge cases early (shift-left); delivered product demos to clients and supported the CX team with extension configuration on client production servers. • Developed comprehensive test plans covering functional, integration, regression, and UAT scenarios; contributed to quality trade-off and risk-mitigation discussions on architecture testability, and applied shift-left practices within a cross-functional team of 12 (QA, Program Management, Development). • Leveraged Cursor, Claude, ChatGPT and Copilot to streamline specification review, test planning, test data creation, and automation scripting, reducing planning effort by an estimated 15%; AI-assisted bug root-cause analysis further accelerated defect triage. In 2025, closed 81 tasks and identified/resolved 171 defects across 17 client implementations.

   • Executed test strategy for large-scale .NET-based enterprise applications (Copperleaf C55) focused on data integrity, reliability, and performance across regulated, high-availability environments. • Developed and executed detailed test plans for API, integration, and system-level testing across customer-specific implementations aligned with agile sprint cycles. • Performed risk-based test planning and led defect triage and root cause analysis with engineering teams, reducing rework and improving release stability. • Supported UAT, production validation, and post-release verification; partnered with Product, Operations, and DevOps to validate business requirements and drive shared quality practices. • Developed and maintained XML-based automation test sequences within an established Selenium framework, composing multi-step workflows covering UI validation, field population, data import, client-specific business logic, and automated regression testing. Adapted existing test suites for new client implementations and created supporting automation test data. • Automated validation of generated Excel reports by maintaining comparison configurations, defining tolerance and rounding rules, and verifying report accuracy against approved baseline templates; integrated automated test suites into CI/CD pipelines after code review and Git pull requests, debugging automation failures across client-specific AWS environments. • Supported junior QA analysts with test design, defect reporting, and troubleshooting practices (RDS testing, instance creation, Oracle troubleshooting); in 2024, closed 36 tasks across 11 enterprise clients, creating 115 defects and verifying 24 additional defects.
