This project involved developing a web application to integrate and support major clients of a vacation rental portal. The solution allows users to update data from a client site to the vacation rental portal with only one click, using personalized scheduling.

As the QA engineer in a small QA team, I provided test planning, design, and execution. I used functional testing for new features, regression testing for release candidates, and smoke testing for released versions in production. In addition, I provided defect reporting and verification, risk management, and coordination of integration testing with other teams.

Challenges:
• Establish QA processes from scratch.
• Mentor and formal lead for a team of two QA engineers.

Achievements:
• Switched from a classic test case description to a BDD approach, which increased the level of transparency between the engineering and Product teams. In addition, it helped speed up automation testing coverage of existing stable functionality.
• Successfully migrated test cases from Rally to Zephyr, adjusting the testing process and workflow to align with the new tool.

An internal tool for consolidating all properties and payment data of big advertisers under a single account, saving all relations between owner and clients.

As the single QA engineer, I provided requirements analysis and clarification, test planning, design, execution, and bug management. I also have been preparing testing summary reports for the team and the product owner. In addition, I facilitated cross-team meetings focused on cross-team integration testing of related products.

Challenges:
• Prepare appropriate test data for accurate financial calculation testing.
• Align cross-team communication and collaboration.

Achievements:
• Prepared test data and performed manual functional testing, which improved defect detection efficiency by 25%.
• Reduced bug fix time by conducting root cause analysis using Splunk, Chrome DevTools, MySQL

A web-based platform that integrates and updates data from major clients to the main platform. This tool streamlined the integration process for new clients and efficiently served existing ones by monitoring changes on the client side and automatically synchronizing with the global platform. The current system uses RESTful microservices for data updates.

I supported the existing framework for API testing and created new scripts to cover new RESTful services using Java with Selenium. I also adopted the company performance testing process, including developing test scripts for performance, load, and stress testing. In addition, I partially acted as QA lead by collecting cross-team QA metrics, providing quality project health checks, and developing improvement plans.

Challenges:
• Switch from pure manual QA activities to API automation testing on Java.
• Adopt existing performance testing processes at the project.

Achievements:
• Refactored the test script base and adopted existing internal tools to optimize the existing automation framework.
• Established the company's performance testing process using JMeter-enhanced reporting by BlazeMeter to ensure new services are ready to release.

A digital product design platform that enables designers to create interactive prototypes, collaborate in real time, and gather feedback from stakeholders.

As a QA lead, I recruited, mentored, and managed a 15-person QA team, optimizing workloads to maximize efficiency and career growth through targeted development paths and skill assessments. In parallel, I provided manual testing for the whole platform and the specific engineering team.

Challenges:
• Managing resource limitations by selecting an optimal test strategy, implementing quarterly test planning, and focusing on critical functionalities.
• performing planning activities for the whole QA team and managing the load of team members.
• Frequently adjusting the testing process according to company strategy and development changes.

Achievements:
• Established a structured test management process using TestRail and Kanban methodology in Jira, resulting in a 40% productivity increase within six months.
• Conducted knowledge-sharing sessions, implemented early functional testing, and planned regression testing with an impact matrix. These efforts improved quality by 20% and reduced issue detection time by four days.

The scheduling functionality for web and mobile products to help therapists provide life-changing care for autism. This functionality connects major user flows and integrates with all Elemy products.

As a single senior QA engineer in command, I planned future testing, designed test plans, prepared test cases and test data, and provided functional and regression testing for scheduled releases. My responsibilities included defect reporting and verification, risk analysis, biweekly demos, and QA process optimization. I also participated in QA team initiatives to provide better quality for all Tilly products.

Challenges:
• Limited amount of test users with complex pre-setup process.
• High level of impact on other products.
• Frequently changing scope, priorities, and release schedule.

Achievements:
• Integrated QA processes within the SDLC, delivering test planning, execution, and reporting.
• Led biweekly demos on product quality, boosting team and stakeholder engagement.
• Designed a reusable test data framework with detailed guides, adopted by five teams, which reduced testing time by 25% across all phases in QA, Product, and development teams.
• Reduced bug fix time by conducting thorough root cause analysis.

The PPMS project focuses on adopting Oracle Primavera Unifier, OPC, and P6 to standardize portfolio and project management and improve visibility into progress, budget, and forecasting.

I joined as QA, owning SIT testing end-to-end—tech spec review, test case design, execution, defect reporting/verification, and summary reporting. In phase two, I helped fix a disorganized requirements review process by restructuring it into clear steps and leading clarification meetings with SMEs and vendors to reduce rework. I served as the main liaison between business and technical teams, since the PM's focus was development, not requirements.

CHALLENGES
• Owning full-cycle SIT testing while untangling requirements-to-test mapping.
• Coordinating business-technical alignment directly, as PM focused on development.
• Validating documented workflows against real business processes.

ACHIEVEMENTS
• Led visual workflow mapping, closing gaps between documented and actual processes.
• Designed end-to-end SIT integration flow, foundation for UAT design.
• Built requirements traceability linking requirements to acceptance criteria.
• Validated workflows/integrations, cutting escalations.
