Project history
Enterprise B2B Subscription & Payment Gateway Platform (Fintech)
- Business Scope: High-throughput B2B subscription payment engine processing recurring transactions via Stripe, Adyen, and PayPal under strict PCI-DSS compliance across EU and US markets.
- Federated Leadership Model (QA Chapter): Established and led a matrixed QA Chapter comprising 5 QA Engineers embedded across 3-4 cross-functional product squads (30-40 division members). Defined technology roadmaps, Playwright standards, and code review practices while product squads executed daily sprint tasks.
- Architecture Modernization & Performance: Eliminating massive legacy technical debt (slow Selenium suites and manual regression blocking production releases). Architected a Playwright + TypeScript test harness from scratch, shifting focus to REST API testing and Contract Testing (OpenAPI/Swagger/Pact). Reduced full regression execution time from 12+ hours to under 20 minutes per GitHub Actions pipeline run.
- Secure AI Workflows: Deployed Cursor and Claude Code across QA using custom .cursorrules and data masking to enforce strict financial privacy. Utilized @Codebase local indexing to accelerate QA onboarding in complex domain logic.
- Technologies: Playwright, TypeScript, REST API Testing, Contract Testing (Pact/OpenAPI), Grafana k6, GitHub Actions, AWS Cloud, Cursor, Claude Code, .cursorrules, Docker, PostgreSQL, Redis, Stripe API, Adyen API, PayPal API, Jira, Allure.
Short-Term QA Audits, Advisory & Presales Consulting (Intermittent)
- QA Process Audits: Conducted 2-to-3-month specialized QA health checks and process audits for software agencies and scale-ups, identifying delivery bottlenecks, flaky tests, and test-coverage gaps.
- Presales & Technical Architecture: Provided technical presales support, estimating test automation efforts, selecting tech stacks, and drafting quality roadmaps for client bids prior to project kickoff.
- Education & Mentorship: Created specialized training modules for the Testeroni platform, mentoring over 1,000+ QA professionals on Playwright, CI/CD integration, and AI-driven quality engineering.
- Technologies: Playwright, TypeScript, Python, k6, Pact, Flutter Mobile testing concepts, CI/CD Audit, TestRail, Zephyr, Proposal Design.
Premium Calculation Engines & Customer Portals (Insurtech)
- Context & Business Scope: Enterprise insurance calculation systems (Life and Automotive) evaluating risk algorithms and policy pricing using complex multi-variable input forms.
- Data-Driven Test Automation: Built a scalable, hybrid Data-Driven Testing (DDT) framework using Python and Robot Framework capable of dynamically evaluating thousands of input combinations (customer age, risk - history, geographic location) against API mocks.
- Quality Gates & DevOps Orchestration: Led a 4-person QA team and partnered with DevOps to establish deployment pipelines in Jenkins. Implemented rigid Quality Gates preventing builds from reaching staging environments unless API regression suites achieved a 100% pass rate.
- Legacy Migration & BDD: Migrated legacy test cases into BDD-compliant suites (Robot Framework / Cucumber), streamlining communication between QA engineers, domain experts, and business analysts.
- Technologies: Python, Robot Framework, Data-Driven Testing (DDT), Cucumber, BDD, REST API Testing, Jenkins, Docker, SQL, API Mocks, Allure Reporting, Jira, Confluence.
