Projects
Automated Video Media Processing & Distribution Pipeline
An event-driven media automation pipeline designed to modernize the fansubbing workflow. By automating the entire technical delivery pipeline, including encoding, muxing, and distribution, the system eliminates manual bottlenecks and reduces operational workload, allowing localization teams to focus purely on human-driven creative tasks like translation and typesetting.
Python-based Document Information Generator System
An automated document engine designed to streamline BPOM regulatory compliance for cosmetic registration. By replacing manual document creation with centralized relational data mapping and asynchronous background processing, the platform automates the generation of structured Dokumen Informasi Produk (DIP). The system ensures real-time revision synchronization, reduces generation turnaround times to under five minutes, and cuts cloud subscription costs through secure internal document handling.
Log & Performance Tracker
A lightweight, self-hosted observability dashboard designed to centralize internal system monitoring without the overhead of external platforms like Grafana or the ELK Stack. The system consolidates scattered telemetry—including server health, API performance, application exceptions, database activity, and local office network connectivity—into a unified interface. By providing real-time status tracking and visual trend analysis, the platform significantly improves visibility into system reliability, streamlining troubleshooting and operational performance management.
Local File Sharing System
An offline-first desktop application engineered for secure, low-cost file sharing and backup across a local network without internet dependencies or cloud infrastructure. Designed specifically for internal R&D formulation teams, the system enables seamless workstation synchronization entirely within an isolated local network environment. Built as a tailored, zero-maintenance alternative to complex self-hosted cloud suites, it prioritizes absolute data privacy, rapid local transfers, and operational simplicity.
