Masenko PROFILE
Middle QA Engineer
4 years testing web services and APIs in microservices teams. At my current job I own QA for a
20+ service platform: weekly releases, 2000+ test cases in rotation, API contract validation

against OpenAPI specs, and daily triage of CI failures. Actively growing into automation —

completed Hillel QA Automation Python (2025, EXCELLENT), hands-on with pytest, httpx, and

in linkedin/blvckcatswag GitHub Actions. I work alongside AI-assisted development: I know which defect classes
gh github/blvckcatswag LLM-generated code tends to miss — untested edge cases, negative scenarios, contract
mismatches — and I test for them by default.

Ukrainian Native
Owned QA coverage for a 20+ microservice platform — 2,000+ test cases maintained across
Russian Native weekly release cycles.
English B1
Validated API contracts against OpenAPI specs in Postman; caught doc-vs-behaviour gaps on
COMMERCIAL STACK 10+ integrated services before they reached production.
Postman REST API OpenAPI
Triaged pytest failures in Jenkins/GitLab CI: isolated root causes per service, cut AQA team's
SQL MySQL Jira debugging loop with structured failure reports.
Jenkins GitLab CI Git MySQL test data ownership: SQL-based setup/teardown for each cycle, entity relationship
Confluence TestRail Scrum validation across service boundaries.
Python pytest Linux Tested LLM-generated code shipped by AI-assisted developers — flagged untested edge
cases, missing negative scenarios, and contract mismatches as a repeating defect class.

REST API Test Suite — Hillel final project github/blvckcatswag
pytest + httpx: fixtures, parametrize, conftest, setup/teardown — written by hand, not
generated.
Positive, negative, and edge case coverage; modules split by endpoint domain.
GitHub Actions CI: tests run on every push, pass/fail visible in PR status checks.
pytest httpx fixtures parametrize GitHub Actions CI/CD

AI-Assisted Test Generation — ongoing practice
Prompt LLMs for test case drafts, then manually gap-analyse and harden coverage — cuts
design time, not quality.
Built a repeatable workflow from daily work with AI-generated code: spec → draft → edge case
audit → final suite.
