Where I've worked

  1. Research and Development InternNational Taiwan University of Science and Technology · Jun - Aug 2026Internship
    Taipei, Taipei City, TaiwanOn-site
    • Collaborated with a team to build a knowledge-based system using knowledge graphs to help LLMs retrieve relevant information and generate answers grounded in laboratory meeting records.
    • Implemented hybrid retrieval combining Qwen3-Embedding-0.6B embeddings with RDFLib graph traversal and RDF4J/SPARQL integration to provide answers with traceable source references.
    • Built relation validation to quarantine unverified graph connections while preserving evidence for review.
    • Benchmarked retrieval on 30 questions from three meetings: graph retrieval passed 30/30 acceptance cases, compared with 22/30 for the vector baseline.
  2. Machine Learning EngineerAvalon AI Group (PT. Automasi Visi Analitika Optima) · Oct 2025 - Jan 2026Seasonal
    Surabaya, East Java, IndonesiaHybrid
    • Developed Python scraping pipelines with Selenium and BeautifulSoup to collect Matahari product details and images, organizing color and size variants in SQLite for Aura Intelligence.
    • Contributed to personal color analysis using MediaPipe facial landmarks, OpenCV, and K-Means clustering to extract dominant skin, eye, and eyebrow colors for personalized fashion recommendations.
    • Implemented CIELAB and HSV color-space analysis, skin-tone scoring, and facial color contrast to support 12-season personal color classification.
    • Built FastAPI endpoints for image-based color analysis, returning seasonal classifications and recommended palettes for the fashion assistant's customer-analysis workflow.
  3. Software Research and Development AssistantSoftware Engineering Laboratory, Informatics Engineering ITS · Aug - Nov 2025Part-time
    Surabaya, East Java, IndonesiaOn-site
    • Led the development team and contributed across the full stack to build a mobile task-management and scheduling application using React Native (Expo), Go (Gin), and PostgreSQL.
    • Implemented LLM orchestration in Go, integrating the OpenRouter API and MCP tools for conversational task management and scheduling.
    • Integrated Google Calendar and Google Tasks APIs with OAuth 2.0 so the assistant could manage calendar events and tasks on users' behalf.
    • Evaluated the application with 30 participants, achieving a System Usability Scale score of 73.67 and an AI-assisted scheduling Task Success Rate of 83%.
