What I'm looking for

Seeking a remote QA Engineer or Senior QA Analyst role focused on functional, integration, regression, SIT/UAT, and end-to-end testing. Especially interested in fintech, payments, banking technology, SaaS, and integration-heavy environments, with opportunities to grow further in automation and API testing.

QA Engineer and Acting Senior QA Analyst with experience across banking technology, payments, production systems, and software testing. I’ve built and maintained 1,000+ test cases and supported SIT/UAT, regression, integration, and end-to-end validation across 13+ banking and payment systems.

My experience includes ATM, POS, SoftPOS, mobile, e-commerce, settlement processing, SQL, UNIX/AIX, and production validation. I also validated a processing optimization that reduced a critical XATMFULL cycle from about 4 hours to 1 hour 37 minutes.

I’m particularly interested in QA Engineer, Senior QA Analyst, payments QA, fintech, and integration-testing roles, with continued growth in API testing and automation.
