About
I'm Arnold, a software engineer from Indonesia who loves turning complex systems into reliable, high-quality products people actually enjoy using. My work sits at the intersection of quality engineering, automation, and thoughtful product development.
I care about clean code, reliable systems, and shipping products that actually make a difference.

Experience
From engineering student to product builder to QA — shaped by hands-on experience across ML, iOS, product, and testing.
Driving software quality at Growise Inc, an SaaS startup focused on data-driven TAM AI solutions. Responsible for end-to-end testing — from test planning and manual regression to Playwright-based automation. Partnering with engineers to shift testing left, integrate CI/CD pipelines, and ensure fast, high-quality releases.
Built the design and delivery of a modular product architecture — a flexible, component-based system that decouples features so they can be independently built, deployed, and scaled. Each module (learning content, assessments, progress tracking, reporting) operates as a standalone unit with well-defined interfaces, enabling cross-functional teams to ship in parallel without creating interdependencies. This significantly reduced feature delivery time and made the platform easier to maintain and extend.
Built data-driven products that helped educators and learners make better decisions. Led development of analytics dashboards, AI-powered recommendation tools, and internal reporting systems — translating raw data into actionable insights across the Sekolahmu platform.
Apple Developer Academy @ UC
Designed and shipped production-ready iOS apps using Swift, SwiftUI, and UIKit through Apple's intensive developer program. Gained deep experience with Apple's Human Interface Guidelines, agile collaboration, and challenge-based learning — building real apps from concept to TestFlight.
Bangkit Academy · Google, GoTo & Traveloka
Specialised in machine learning through an intensive program backed by Google, GoTo, and Traveloka. Collaborated with Indosat Ooredoo Hutchison on a capstone project — training and deploying a classification model to solve a real-world business problem.
Institut Teknologi Sepuluh Nopember (ITS)
Studied computer engineering with a focus on software systems, algorithms, and data structures. Actively participated in national competitions and technology communities throughout the degree.
