I built an AI-powered IELTS Writing readiness platform that helps learners practice and improve their writing through intelligent feedback. Users can generate Task 1 and Task 2 prompts on demand, complete their essays, and receive AI-driven analysis that highlights grammar mistakes, suggests corrections, and predicts band scores. The system also provides interactive explanations for each correction, helping users understand their errors and improve their writing skills more effectively.

The platform includes a practice history feature that stores previous essays, corrections, and feedback results, allowing users to track progress and identify recurring mistakes over time. Built with a cost-efficient AI orchestration strategy and Firestore-based storage, the system focuses on performance, scalability, and accessibility. By combining realistic exam-style prompts with structured feedback and progress tracking, the platform aims to provide a practical and flexible way to prepare for the IELTS writing test.

I built Smart Shortcut Panel, a productivity-focused Chrome extension designed to make bookmark management more contextual and efficient, especially for users who frequently work with AI tools such as ChatGPT, Perplexity, Claude, and other web-based productivity platforms. The extension provides a floating shortcut panel that dynamically displays relevant bookmarks based on the website being accessed, allowing faster navigation to important pages such as AI conversations, prompt libraries, dashboards, or research tools without searching through traditional bookmark folders.

The extension supports customizable keyboard shortcuts, enabling users to instantly open frequently used pages while staying within the same browsing session. It is built using the Chrome Extensions API, utilizing service workers and content scripts to create a lightweight and responsive interface. With privacy as a core principle, all bookmark data is stored locally on the user’s device, with encrypted storage used to protect user configurations, ensuring a seamless and secure browsing experience without tracking or unnecessary background processes.

As a Certified Ethical Hacker (CEH) and Certified Threat Intelligence Analyst (CTIA), I have identified multiple security vulnerabilities across government websites, including sensitive information disclosure, admin account takeovers, API endpoint exploits exposing personal employee data, and password pattern analysis revealing potential security risks. One of these findings was formally recognized through a Hall of Fame acknowledgment by BPK (Supreme Audit Board of Indonesia). Due to confidentiality considerations and institutional reputation, several additional findings remain undisclosed.

A cybersecurity innovation I developed received an Innovation Award at the Indonesian Ministry of Finance hackathon for addressing institutional security challenges, and the solution was later implemented at the national level to help strengthen organizational security capabilities.

I was also selected as a finalist in the Ministry of Finance Hackathon and the Bank Indonesia – OJK Hackathon 2025, where the solutions focused on improving threat detection, strengthening system resilience, and supporting safer digital financial ecosystems. In addition, I won the Ministry of Finance Data Analytics Community (MoF-DAC) competition by applying advanced analytics techniques to enhance information security monitoring and risk detection.
