Skills

  • Test Automation Architecture & Framework Design

    Internal NPM framework used by 12+ engineering teams across 20+ projects — 5 adopted it immediately; now the QA chapter standard.

  • Test Automation Stack & Languages

    Playwright, Selenium, Rest Assured, WebdriverIO · Java, JavaScript, TypeScript — the stack the shared framework's 20+ projects are written in.

  • CI/CD (Jenkins, Docker, Bitbucket)

    Rebuilt CI/CD pipelines on open-source tooling — recurring licensing costs eliminated, delivery velocity maintained.

  • AI-Driven QA (MCP, RAG, Prompt Engineering, Agentic AI)

    MCP servers and AI agent skills used by 30+ engineers; agentic coding harnesses standardized org-wide.

  • NPM Module & Platform Architecture

    Published npm package (deepindex); replaced forked, duplicated automation code with one modular NPM dependency model.

  • Quality Dashboards & Reporting

    Real-time quality dashboards giving stakeholders test-health visibility for data-driven prioritization.

  • Cross-Team Technical Leadership & Mentorship

    Primary technical point of contact for QA automation architecture across the department; led code reviews as primary reviewer.

  • Performance & Load Testing (ReadyAPI, LoadUI, Postman)

Senior Software Engineer in Test

Chubb

Sept 2023 — PresentLeof. Georgikis Scholis 27, Thermi, 57001 Thessaloniki (Greece)

  • Designed an internal NPM automation framework now used by 12+ engineering teams across 20+ projects; after an internal presentation, 5 projects adopted it immediately, and it went on to become the standard framework across the entire QA chapter, replacing duplicated, forked automation code org-wide.
  • Serve as the primary technical point of contact for QA automation architecture and design decisions across the department, advising teams on framework structure, tooling choices, and test strategy.
  • Deployed MCP servers and AI agent skills used by 30+ engineers, making testing know-how and technical context retrievable at the point of work instead of buried in documentation.
