Allan Haljasmaa

I've tested high-traffic consumer platforms at NUUM and Wildberries across web, iOS, Android, and backend services. My work covers full-cycle manual testing, from requirements analysis through release validation.

At NUUM, I tested 12+ interconnected microservices and 40+ API endpoints, validating Kafka communication, PostgreSQL data integrity, and production-facing logs in Kibana. I built reusable Postman collections with pre- and post-request JavaScript scripts, investigated defects through request and user identifiers, and used Charles Proxy to test network, offline, and rewritten-response scenarios.

At Wildberries, I performed functional, end-to-end, integration, regression, smoke, performance, and usability testing for the customer mobile app on real iOS and Android devices. I maintained test plans, test cases, and checklists in TestRail while working closely with backend integrations and business requirements.

I'm comfortable contributing in Scrum and Kanban teams, collaborating with engineering, product, and DevOps, and bringing detailed evidence to every bug report through logs, screenshots, recordings, and clear documentation.
