// 01 — About

Five years of shipping Android with clean architecture, a security-first mindset, and codebases built to outlive the sprint.

I am a self-taught programmer with a deep passion for technology and problem-solving. I have over five years of professional Android and mobile development experience. With a strong foundation in software engineering, I focus on building intuitive, high-performance applications while continuously refining my skills.

I thrive in fast-paced environments, adapting to new challenges and staying ahead of technological advancements. My dedication to innovation and excellence drives me to optimize performance, enhance security, and streamline system architecture.

Beyond Android, I have taken courses in front-end web development, back-end development, DevOps, and machine learning. That range lets me bring a holistic perspective to a project rather than only a mobile one.

Feb 2024 — Present

PT Privy Identitas Digital

Android Engineer

I specialize in building an SDK for liveness detection. Within two months I refactored and cleaned up the codebase — fixing memory leaks, improving performance, and making it maintainable. Since then my focus has been hardening its security, optimizing it, and making it straightforward for other teams to integrate.

Built PrivyChat, an in-app chat feature, from scratch

Migrated OCR from ML Kit to OpenCV, reducing the app's size and improving card detection

Implemented security improvements that prevent deepfake injection attempts, hardening the system against fraud and abuse

Reworked the SDK's public API so consuming teams can integrate it with less setup

Work daily with single-activity architecture, face detection, CameraX, and WebSocket integration

Mar 2022 — Feb 2024

Ideku Technology Solution Pte Ltd

Android Developer

For a year and a half I was the sole Android developer. I taught myself clean architecture from communities, articles, and the Android documentation, then refactored the codebase repeatedly until the architecture fit the product. When an experienced Android developer joined, we decided together to extract a shared library and formalize our practices.

Integrated the app with multiple models of thermal printer

Designed the system architecture and developed a POS application

Built a shared library so all company products could be maintained from one place

Monitored system performance, fixed bugs, and tracked stability across platform versions

My first professional role, starting on native Android. When a Flutter project appeared I volunteered, learned it quickly, and became an active contributor. I proposed and led improvements to project management, QA, and CI/CD.

Responsible for mobile app development in Flutter

Maintained and built new features for an Android app in Java

Ran quality control and testing across all website and mobile projects before client handover

Simple Socket

I built the Simple Socket Android Library to solve a communication problem at my company: several apps on different devices needed to talk to each other over peer-to-peer socket connections. It taught me Maven publishing and how to design an Android library others have to live with.
