QA Automation & Systems Specialist | Manual, API & Workflow Testing
Is this you?
Releasing features but bugs keep slipping into production?
Manual regression slowing down your delivery cycles?
Struggling to validate complex workflows across systems and integrations?
- Manual & Regression Testing
I design and execute structured test plans covering functional, regression, integration, and end-to-end scenarios across enterprise systems. I ensure business workflows, edge cases, and data integrity are validated before release to protect system stability and user experience.
- Automation & Workflow Testing
I build and maintain automation test scripts for critical user flows to reduce repetitive manual work and increase coverage. My focus is practical automation that supports faster releases while maintaining reliability and traceability.
- API Testing & Integrations
I test REST APIs using Postman, collaborating closely with developers to build and maintain reusable collections. I validate request/response structures, status codes, chained workflows, and data synchronization across integrated systems.
- Enterprise Systems & Data Validation
I have experience testing large-scale systems including digital banking platforms and smart metering infrastructure projects. I verify database updates, field transactions, and backend integrations to ensure operational accuracy and compliance.
- Agile QA & Process Improvement
I work within agile teams, participating in sprint planning, backlog grooming, and release readiness activities. I continuously improve QA documentation, regression coverage, and defect triage processes to strengthen overall delivery quality.
