Jakarta-based QA automation engineer testing a payment gateway back-office portal that bridges local and international banks. I own the Katalon Studio framework, hold release sign-off, and build my own tools with Playwright, Flutter and AI agents — backed by a mobile developer background. Working remotely across time zones.
From manual test design to automation and self-built tooling — delivered remotely for teams in Indonesia, Malaysia, Singapore and beyond.
Functional, regression, API and cross-browser testing for web, Android and iOS. Test cases, bug reports and test cycles in Jira.
Learn more →Data-driven automation with Katalon Studio (Groovy), Selenium WebDriver and Playwright — plus trackers that report progress automatically.
Learn more →Flutter apps and games, ASP.NET web apps, and Python / Node.js scripts — built from my developer background.
Learn more →AI-assisted test execution, Claude skills (SKILL.md), MCP integrations and local agents that automate repetitive QA work.
Learn more →Curious how a tool was built, or want to swap QA automation ideas?
Say hello →Personal and portfolio projects. Work-related tools are shown with dummy data — no client or company data is exposed.
A quality playbook for a banking back-office platform defining who owns quality at each release stage — separating QA (prevention: strategy, entry/exit criteria, audits) from QC (detection: functional, regression, go/no-go evidence), built on ISTQB principles.
Endless runner starring a red toy poodle — one Flutter codebase released to Web, Android and Windows. Custom physics, code-drawn art, procedurally generated chiptune audio, EN/ID localization, and platform bugs fixed across Android, web and iOS Safari.
Play it →Now Showing and Coming Soon movies across Indonesian cinemas (XXI, CGV, Cinépolis), with direct booking links. Data stays fresh via TMDB.
An AI-agent skill that runs test cases from a ticket, captures full-HD evidence, fills executions with comments, and raises bug sub-tasks.
View on GitHub →Playwright tracker that reads monthly test cycles in Jira and reports execution progress — rolls over to each new month automatically.
View on GitHub →Checks every epic and child issue against published documentation pages, flags missing fields and links, and reports what's still pending.
Turns a support report ticket into a ready-to-send on-duty escalation message for MS Teams — no more typing it by hand.
Android app that finds any customer in seconds — one search box for code, name, address or phone — powered by the ASP.NET backoffice I built for my store.
Data-driven Katalon suite that logs in, inserts many customers from Excel in one run, and logs out — demoed with dummy data.
A Claude skill that turns a Jira epic into an SOP-compliant user guideline page with masked screenshots and an automated layout audit — cutting creation time from 1 hour to 20 minutes per task.
C# command-line tool for guideline work: diffs Jira against published pages, checks SOP rules and auto-fixes formatting, validates fields with a dry run first, and censors screenshots. No AI, no paid APIs.
Builds each month's release test cycle automatically: queries sprint epics via the Jira REST API, traces linked test cases, adds them in verified batches and sets assignees safely — next month takes one instruction.
Reads Chinese promo boards, converts CNY to IDR with a fixed pricing formula, and generates Shopee listings plus Instagram carousels and captions — one prompt per batch.

Edufund education-funding app (React Native, MySQL) · Diamond Store Grocery Website (ASP.NET MVC, VB.NET) · MyShop Online Store (PHP, CodeIgniter) · Sanjaya Grocery Sales & Purchasing Website (ASP.NET MVC, VB.NET)I treat quality as a process, not a phase — and I document it so the next person can pick it up.
Test cases, scenarios and cycles mapped to each epic and story.
Web, Android and iOS — cross-browser and cross-device.
REST testing in Postman, data checks with SQL / MySQL.
Katalon, Selenium and Playwright to cut regression time.
Reproducible steps, evidence screenshots and severity in Jira.
User guidelines, SOP ownership, progress tracking and reporting to management.
Also working with: Bitbucket & GitHub CI pipelines, ISTQB principles, BookStack, Confluence, Git, Netlify, FileZilla, PIL / NumPy, Canva.
A developer's mindset applied to quality: if a task repeats, I automate it; if a process is unclear, I document it.
I run my own online shops end to end — listings, pricing, customer service, invoicing and the tools behind them.
Pre-order shop for official Genshin Impact merchandise on Shopee and Instagram. Running since 2021.
@vita_shopper →Pre-order official Honkai: Star Rail and Zenless Zone Zero merch, plus EVERYS Collagen Jelly reselling on Shopee.
@kirisuna.shop →Access to premium digital tools such as Canva Pro, with an invoice automation tool I built in Node.js, Playwright and OCR.
@vitasmarthub →Testing a payment gateway back-office portal that bridges local and international banks. Own the Katalon Studio framework (rebuilt from a legacy version with reusable keywords, page objects and data-driven Groovy tests), cutting full regression to ~2 hours with 150+ automated cases run in Bitbucket/GitHub CI. Test payment and withdrawal flows across 5+ bank and payment channels, hold final release sign-off within a 17-member QA team, and have mentored 4 junior QA engineers. Also own the team's user guideline SOP and automate team workflows with Playwright and AI.
Run Shopee and Tokopedia hobby stores and the Vita Smart Hub digital tools store — listings, payment verification, delivery and customer support — plus personal automation projects (Katalon, Playwright invoice generation with OCR).
Moved from mobile development into QA: functional, regression and UAT testing each release, with structured test cases and reproducible Jira defect reports.
Developed Android app features in Flutter and Firebase, working with QA to improve testability and release testing.
Implemented React Native features for an education-loan mobile app (Edufund), including unit testing and debugging.
Thesis: a mobile fintech app for education loans built with React Native (case study: Edufund).
