Oleksandr Semenov

QA Engineer (Web + API) with experience testing a B2B SaaS product in the email and omnichannel marketing domain (campaigns/templates, automation workflows, integrations, roles/permissions, billing). I run release smoke/regression, validate critical end-to-end user flows (positive/negative), and reproduce issues quickly while working closely with product and developers. I test APIs with Postman/Swagger and validate data using SQL (PostgreSQL via DBeaver). I also develop and maintain UI/API automation in Java + Selenide, keeping the test suite stable and reliable.
