Hi, I’m Hirok Sarker — a Senior QA Automation Engineer and Team Lead with 14+ years of experience in automation, performance, and security testing across fintech, POS, blockchain, and large-scale event platforms. Currently, I work remotely with Cantaloupe (CHEQ Platform, USA), where I lead end-to-end automation for POS, kiosk, and Flutter-based mobile systems serving 100K+ daily users across stadiums, restaurants, and cruise lines. I specialize in building scalable test automation frameworks using WebdriverIO, Appium, and TypeScript, and have driven automation coverage that reduced manual testing efforts by over 70%. My work also involves high-concurrency performance testing (1M+ simulated users) and security validation using OWASP ZAP, Burp Suite, and Kali Linux for PCI DSS and SOC2 compliance. Before joining CHEQ, I led QA teams at Kona Software Lab (South Korea) and OnnoRokom Software, where I contributed to fintech, blockchain, and education ERP projects used by millions of users daily. I’m passionate about mentoring teams, designing intelligent automation pipelines, and bridging QA with DevOps to achieve continuous quality at scale. 🧠 Tech Stack & Focus Areas Automation: WebdriverIO, Appium, Selenium, Playwright, Cypress, REST Assured Performance: JMeter, K6, Gatling Security: OWASP ZAP, Burp Suite, Kali Linux DevOps/Cloud: Jenkins, Docker, Kubernetes, AWS Languages: Java, TypeScript, Go, Python, Bash 🎯 What I Offer on Topmate ✅ QA Automation Mentorship (WebdriverIO, Appium, Playwright) ✅ Career Guidance for SQA Engineers (framework building, leadership track) ✅ Resume & Portfolio Review for QA/Automation roles ✅ Performance & Security Testing Deep Dives ✅ Consultation on DevOps integration for QA pipelines
