Manual Testing · API Testing · AI Quality Assurance
I'm Elena Stefanovska, a QA professional with 9+ years of experience testing web, mobile, SaaS, and API-driven applications. I focus on understanding complex business workflows, identifying risks, and helping teams deliver reliable software.
Quality starts with understanding.
My approach to QA goes beyond checking whether a feature works. I aim to understand the business purpose behind the software, explore dependencies, identify risks, and validate how complete processes behave in real-world scenarios.
My experience spans SaaS applications, financial and payment workflows, APIs, event-management platforms, and AI-assisted functionality. I have also worked closely with developers, product stakeholders, and international clients.
What I bring to the table.
A combination of technical testing, analytical thinking, business understanding, and collaborative problem-solving.
Technical & API Testing
- REST APIs, HTTP, and JSON
- Postman and Swagger / OpenAPI
- Third-party integrations
- Chrome DevTools and Charles Proxy
- Basic SQL and data validation
Product & Business Quality
- Requirements analysis
- Complex business and payment workflows
- Cross-module testing
- Client and stakeholder communication
- Risk identification and prioritization
AI Quality Assurance
- Recommendation relevance assessment
- AI-assisted classification review
- Confidence-level evaluation
- False positive and negative identification
- Human validation and correction of AI results
Beyond finding bugs.
Quality assurance means understanding how systems behave, where risks exist, and what matters to the people using them. Explore selected areas of my professional experience.
Financial & Business Workflows
Testing interconnected inventory, finance, accounting, production and payment-related processes.

The Quality Challenges
Complex business systems contain dependencies between modules. A change in one workflow may affect data consistency, transaction states, or related processes.
My Testing Approach
- Analyze business requirements and dependencies.
- Prioritize business-critical workflows by risk.
- Design positive, negative and boundary scenarios.
- Prepare structured test data.
- Execute end-to-end and cross-module scenarios.
- Investigate defects and verify fixes.
What I Validated
- Inventory and product configuration.
- Commercial and financial document workflows.
- Payment-related functionality and states.
- Accounting and inventory dependencies.
- Business rules and data consistency.
- Regression behavior after changes.
AI-Powered Recommendations & Quality Validation
Validating AI-generated recommendations, reviewing output relevance, identifying unexpected results, and testing complex workflows to ensure functionality aligns with business requirements and user expectations.
Explore case study
The Quality Challenges
AI-generated recommendations require more than traditional functional verification. An output may be generated successfully but still be irrelevant or inconsistent with the intended business context.
My Testing Approach
- Analyzed feature requirements and expected behavior.
- Reviewed AI-generated recommendations for relevance.
- Compared outputs against business expectations.
- Identified unexpected or irrelevant suggestions.
- Validated related application workflows.
- Investigated inconsistencies and communicated findings to development teams.
- Applied functional, exploratory, and risk-based testing approaches.
What I Validated
- AI recommendation relevance.
- Alignment with business requirements.
- Expected and unexpected system behavior.
- Functional integration with related workflows.
- User-facing functionality and consistency.
