NDA case study
Connected-device Test Infrastructure
Playwright and Selenium suites for React/TypeScript device registration, authentication, and multi-locale flows, backed by Jenkins quality gates.
Context
Resume-backed consultant engagement through emagine Consulting for a connected-device platform. Client naming stays anonymized for public portfolio use.
Problem
Registration, authentication, and localization flows needed repeatable coverage across modern React/TypeScript surfaces without growing manual test-authoring work.
Role
Built UI/UX automation suites, expanded coverage with LLM-assisted test generation, and integrated automated checks into Jenkins quality gates.
Constraints
- Multi-locale behavior had to stay legible to product and engineering teams.
- Coverage needed to scale without adding headcount.
- Tests had to move defect detection earlier than staging.
Approach
Combined Playwright and Selenium coverage for critical UI journeys, used AI-assisted case expansion where it saved time, and tied the suites to Jenkins so failures became part of sprint feedback.
Challenges
The useful line was not simply generating more tests. The work was making generated coverage maintainable enough to trust inside delivery pipelines.
Impact
- Reduced manual test-authoring time by 60%.
- Scaled coverage for device registration, authentication, and multi-locale flows without adding headcount.
- Moved defect feedback into Jenkins quality gates before stories reached staging.
Recruiter takeaway
Direct match for senior QA automation and SDET roles using Playwright, Selenium, TypeScript, and CI/CD gates.
Engineering manager takeaway
Shows judgment around where LLM-assisted testing helps and where pipeline reliability still has to be engineered.
