Tailscale turns your scattered devices into a secure, private mesh network—perfect for linking homelabs, laptops, and mobile clients seamlessly across locations.

Tailscale turns your scattered devices into a secure, private mesh network—perfect for linking homelabs, laptops, and mobile clients seamlessly across locations.

Summary

A personal initiative to build a secure, globally accessible homelab infrastructure interconnecting multiple physical locations (Jakarta and Yogyakarta) and various devices using Tailscale. The setup enables seamless, encrypted access to private and public web services without exposing them directly to the internet.

Manage and connect private connection with ease.

Send a chat with a receipt image — AI reads it, logs it, and updates your spreadsheet.

Send a chat with a receipt image — AI reads it, logs it, and updates your spreadsheet.

Summary

Born from frustration with messy financial habit tracking, this project reimagines expense management through everyday chat. Instead of manually logging every purchase, users simply send a quick message or upload a transaction photo to their private WhatsApp chat. The system automatically extracts key details, categorizes the expense, and syncs it directly to Google Sheets for analysis.

A custom-built OCR pipeline leveraging deep learning for real-world numeric and text recognition tasks on utility meters and similar image datasets.

Summary

A freelance project aimed at automating visual data entry from numeric meters (e.g., electricity readings) using machine learning-based Optical Character Recognition (OCR). This system tackles the repetitive and error-prone process of manually transcribing blurred or low-quality meter images by introducing an AI pipeline that reads, processes, and interprets images directly from a web interface.

A web-based deep learning system for classifying handwritten Javanese script characters, enabling users to learn and explore traditional scripts interactively.

A web-based deep learning system for classifying handwritten Javanese script characters, enabling users to learn and explore traditional scripts interactively.

Summary

A research-driven project that applies machine learning to preserve the Javanese script, one of Indonesia’s historical writing systems. This system allows users to draw Javanese characters on a web canvas and receive real-time classification predictions, promoting cultural literacy through interactive technology.

This project served as the implementation of a Bachelor’s thesis, focusing on leveraging transfer learning for handwriting recognition in underrepresented scripts.

Transfer learning meets cultural heritage preservation.

A centralized CMS platform designed for NGO stakeholders to manage volunteers and disseminate real-time disaster information efficiently.

Summary

A full-stack web-based information system designed for an NGO (YAKKUM Emergency Unit) focusing on natural disaster response. The project aimed to streamline volunteer management, activity reporting, and information distribution, ensuring stakeholders and the public have access to real-time, verified updates during crisis events.

This project was developed as part of an internship program, completed by a team of five developers, and served as a fifth-semester academic project.
