Hi, I’m Khemie, a QA Analyst Lead with 9+ years of experience across fintech, airline systems, enterprise retail, e-commerce, and now AI platforms. Currently, I lead QA for GXchange, supporting the backend of wallet operations — from wallet management and liquidity, to settlement, reconciliation, and regulatory compliance. I don’t just execute test cases; I design testing strategies, analyze financial flows, monitor defect metrics, and ensure zero downtime for critical transactions like cash-ins and transfers. Before fintech, I worked with Cebu Pacific where I tested web and mobile booking systems in an agile environment. Earlier in my career, I supported vendor management systems for Carrefour with on-site deployment experience in Indonesia — coordinating between cross-country business and tech teams. Recently, I’ve expanded into AI and e-commerce platforms — testing end-to-end workflows for Sugarwish’s online gifting system, QA for an AI leadership coach at Pinnacle, and validating AI-powered pre-production workflows for RivetAI serving filmmakers. My strength lies in bridging business logic, backend systems, and user experience. I lead testing strategy, mentor QA members, and continuously improve processes — but I’m also deeply hands-on in debugging logs, analyzing APIs, and validating integrations. One of my most significant achievements was leading the successful production release of RR 16-2023 WHT implementation — introducing 1% creditable withholding tax logic into a live financial ecosystem — ensuring compliance without disrupting wallet transactions. I’m passionate about building resilient systems, especially in fintech and AI, where accuracy, compliance, and reliability are non-negotiable. If you’re building fintech, AI, or SaaS platforms and need a QA leader who understands both business risk and system integrity, let’s connect.

Hi, I'm a Software Quality Assurance Expert with about 10 years of experience in both automation and manual testing. During my career, I created many python and Java script-based automation frameworks for different projects, including web, desktop and mobile applications. I create test plans and automated regression cases. Have a lot of experience in load, performance and stress testing using JMeter/Grafana/New Relic. I am ready to help you test automate your application and make it match your requirements and the industry standards

Shipping a bug to production costs you users, revenue and trust, and the bugs that get through are almost never the complicated ones. They are the cases nobody thought to check. I'm an ISTQB-certified manual QA engineer with 100% Job Success across 48 contracts. I test SaaS, web and mobile products the way real users behave, then lock the result behind automated regression suites in Cypress, Selenium and Appium. HOW I WORK: You send me a staging link, test credentials, and one sentence about what is worrying you. Before I touch anything you get a test plan, so you know exactly what I am covering and what I am not. Then I test the way your users actually behave, not the way the demo goes, functional, UI/UX, cross-browser, and real iOS and Android hardware rather than emulators. What reaches your developers is a bug report they can act on without a single follow-up message: exact reproduction steps, environment, expected vs actual, severity, screenshots, and a screen recording on anything critical. Filed in Jira, TestRail or Linear or whatever you already use. Nothing gets closed until I have retested the fix myself. WHERE I CAN HELP: - Manual and exploratory testing for web, SaaS and mobile products - AI chatbot and conversational AI testing, intent matching, context retention, fallback handling and response accuracy - Mobile app testing on real iOS and Android devices, install, update, permissions, offline states, interrupts and in-app purchases - API testing in Postman and RestAssured, negative, boundary and malformed payload cases, auth and token-refresh flows - Regression testing, a full cycle before release, or an ongoing retainer - Test plans, test cases and device compatibility matrices your team can re-run - Test automation in Cypress, Selenium and Appium, wired into your CI/CD - Game QA, structured play tests, progression and save-state testing, in-app purchase and ad flows DEVICES I TEST ON: iOS: iPhone 15 Pro, iPhone 13 Pro Android: Xiaomi 15T Pro (flagship), Samsung Galaxy A55 (mid-range) Desktop: MacBook Pro M4 14-inch, MacBook Pro M3 Pro 16-inch, Lenovo IdeaPad Slim 3 (Windows 11) Browsers: Chrome, Safari, Firefox, Edge Two iPhone generations, flagship and mid-range Android, and both macOS and Windows, so layout, performance and OS-version bugs surface before your users find them. AVAILABILITY: I work the full European day and stay online through US Eastern mornings, so most teams hear back the same day rather than the next one. Send me the build and the part you are least sure about, and I will tell you where I would start.
