About

Quality engineering in payments is not just about finding defects—it is about protecting every transaction before it reaches the customer. I am a Quality Engineer II at JUSPAY with nearly four years of experience across FinTech payment systems, mobile applications, and gaming platforms. I specialise in API, backend, microservices, database, mobile, integration, and end-to-end transaction testing. At JUSPAY, I own quality activities from requirement analysis and risk-based test planning through feature validation, debugging, release readiness, and sign-off. I have supported quality validation for 20+ payment features, including EMI, BNPL, mandates, recurring payments, surcharges, outage handling, merchant integrations, and complex transaction workflows. I go beyond test execution. I investigate failures by correlating REST API responses, SQL records, application logs, metrics, and distributed traces, giving engineering teams clear and reproducible evidence to isolate root causes and resolve issues faster. I also work closely with Product, Backend, Design, and QA teams to improve release quality, usability, documentation, and customer experience. At Paytm First Games, I developed reusable Python-Appium mobile automation workflows that reduced regression execution time by 30%. I also bring hands-on experience in API and backend validation, performance testing, mobile testing, CI/CD quality practices, and WCAG-aligned accessibility testing using VoiceOver and TalkBack.

I am also interested in hands-on Lead QA opportunities where the role aligns with my technical experience and quality ownership. I am currently exploring opportunities across the UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, Oman, the wider GCC, and remote teams. Recruiters and hiring teams working on FinTech, banking, digital payments, API, backend, mobile, automation, performance testing, or product-quality roles are welcome to connect with me or send me a LinkedIn message.
