Hire the Best Test Case Designers
in Indonesia

I am a QA Engineer with 4 years of experience working remotely with clients in the UK, Dubai, and the US. I specialize in building stable automation frameworks and running heavy load tests to ensure your app is production-ready. Unlike many testers who only check functionality, I have a background in UI/UX Design. This means I can spot design inconsistencies and usability issues that usually get missed, saving your developers from going back and forth on revisions. I also leverage AI tools throughout my workflow, from generating test cases and writing automation scripts to analyzing test results faster, which significantly reduces delivery time without sacrificing quality. Highlights from my recent work: ✅ Scale & Stability: Built automation frameworks (Selenium) that achieved a 90% pass rate across 16 business units for a major tech unicorn ✅ Mobile Automation: Built end-to-end mobile automation using Appium, covering 100% of app scenarios to ensure total feature stability ✅ Web Automation: Developed end-to-end tests using Playwright integrated with GitHub Actions CI/CD, ensuring automatic regression checks on every deployment and daily monitoring to highlight any issue post-deployment ✅ Load Testing: Simulated 2,000 concurrent users using K6 to find bottlenecks for a high-traffic app ✅ Payment Testing: Hands-on experience testing payment gateway integrations including Stripe, PayPal, NMI, RyftPay, Midtrans, and Doku covering end-to-end transaction flows, failure scenarios, and edge cases to ensure reliable checkout experiences My Tech Stack: 🌎 Web: Playwright, Selenium, Appium, Cucumber 📱 Mobile: Appium, WebdriverIO (iOS/Android) 📈 Performance: K6 🤖 AI-Assisted: Test case generation, script writing, result analysis ⚙️ Tools: GitLab CI, Jira, Figma, Postman, GitHub Actions 💳 Payment Gateways: Stripe, PayPal, NMI, RyftPay, Midtrans, Doku If you need a tester who can handle technical automation, move fast with AI-assisted workflows, and still has an eye for design quality, send me a message!

Most pitch decks don't fail because of poor design. They fail because the story isn't clear, the numbers are buried, or the investor loses interest before slide three. That's where I come in. I help startup founders turn raw ideas and messy data into investor-ready pitch decks, the kind that get you the second meeting. Whether you're preparing for a pre-seed round, a seed raise, or a Series A, I build decks around one goal, keeping the investor's attention long enough to say yes to a call. With 5+ years of experience and 350+ decks delivered, I've worked with founders across startups, tech and SaaS, real estate, and healthcare/biotech ventures, helping them structure and present a story that holds up under investor scrutiny. When we work together, you'll get: ✔ A deck built around investor psychology, thinking through what gets promoted to a headline, what gets cut, and what number leads ✔ Clear narrative structure before a single slide gets designed ✔ Clean data visuals covering traction, market size, and financial projections ✔ An efficient AI-assisted workflow that supports tight deadlines without compromising quality ✔ A partner who understands fundraising, not just formatting What clients say: "Khoirina was willing to go above and beyond to make our project a success. A great communicator and a pleasure to work with." I specialize in: → Startup Fundraising Decks (Pre-Seed, Seed & Series A) → Tech, SaaS & AI Investor Decks → Real Estate Investment Decks → Healthcare & Biotech Investor Decks → Company Profile & Investor Update Decks If you're raising capital and your deck isn't landing the way it should, send it over. I'll tell you exactly where it's losing people.

The most valuable bugs are the ones your customers never see. Over the past 12+ years, I have logged more than 27,000 hours worth of QA work across 70+ projects. Several client relationships span multiple years and thousands of hours, reflecting the level of trust, consistency, and ownership I bring to every project. I am a Senior Manual QA specializing in GitHub-based development workflows, pull request validation, exploratory testing, and AI-assisted development environments. My role is not simply to find bugs. My goal is to help teams ship with confidence by identifying issues before they reach production, where they become significantly more expensive and disruptive to fix. I specialize in Manual QA for iOS, Android, and Web applications, helping product teams reduce release risk through exploratory testing, regression testing, feature validation, and detailed bug investigation. By uncovering issues early in the development cycle, I help teams avoid costly production incidents, customer-facing defects, and unnecessary rework. Throughout my career, I have worked closely with founders, product managers, designers, developers, and distributed teams to improve product quality and support reliable releases. I enjoy understanding how a product works, exploring user behavior, identifying edge cases, and providing actionable feedback that helps teams make informed decisions before shipping. In addition to traditional QA activities, I regularly work within GitHub-based development workflows, validating pull requests, reproducing reported issues, verifying fixes, reviewing implementation outcomes, and providing structured feedback before changes are merged or released. As development teams increasingly adopt AI-assisted coding tools, QA plays an even more important role as the final validation layer. Recent projects have expanded my responsibilities beyond traditional testing into PR validation, agent-assisted development workflows, QA session orchestration, and structured feedback loops between developers, coding agents, and product teams. Areas of expertise: • Manual Testing (iOS, Android, Web) • Exploratory Testing • Regression Testing • Feature Validation • Release Validation • Pull Request Validation • GitHub-Based Development Workflows • Cross-Device Testing • Bug Investigation & Reproduction • QA Documentation & Reporting • AI-Assisted Development Validation • Agile Product Development Tools and Platforms: • GitHub • Jira / Atlassian • Confluence • Azure DevOps • Charles Proxy • Trello • TestRail • Mixpanel • Loom • Lightshot Device Lab Available for Real-Device Testing: iOS Devices • iPhone 6 Plus (iOS 12) • iPhone 7 Plus (iOS 13) • iPhone 12 Pro Max • iPhone 13 Mini • iPhone 14 Pro Max • iPhone 15 Pro • iPhone 16e • iPod Touch 6th Generation Android Devices • Samsung S7 • Samsung S9 • Samsung Note 9 • Samsung A51 • Samsung A56 Desktop • MacBook Pro 15" • iMac M1 I am particularly interested in long-term collaborations where I can develop a deep understanding of the product, contribute meaningful QA insights, reduce release risk, and become a trusted quality partner for the team rather than simply an external tester.
