The Overview
Project context & goals
An AI accessibility travel companion that checks whether a trip fits a person's access needs before they leave. 1st Place at the IFEST UNPAD 2026 National Hackathon.
Aksesin helps people with disabilities and their companions check a place before going, across five access stages: the drop-off point, the path to the place, the entrance, lifts and stairs, and the facilities inside. It launched with 229 curated places in Bandung and Bogor, the prototype scored 80.65 on the System Usability Scale across 50 respondents, and the team took 1st Place at the IFEST UNPAD 2026 National Hackathon.
I was the top code contributor on the Next.js 16 landing page and staff dashboard, and also worked on the Fastify and Drizzle backend (PostgreSQL with PostGIS and pgvector) and the Expo app. I built Navi, the Mastra-based assistant: Indonesian text chat, live voice conversation, and photo analysis that turns uploads into draft accessibility observations the user reviews before anything is published. I also added personalised onboarding for mobility, vision, hearing, and elderly needs, Mapbox walking routes, staff moderation, and a read-only MCP server for staff.
