How I Built a Visa Tracker with Django, Aurora PostgreSQL, and react

Visa applications are stressful. You have dozens of documents to collect, country-specific requirements to meet, and strict deadlines to hit — all with zero visibility into where you actually stand. I built VisaTrack to fix that: an AI-powered document tracker that generates your required checklist automatically, lets you track progress, upload files, and get guidance from an AI advisor.

I built it for the H0 — Hack the Zero Stack with Vercel v0 & AWS Databases hackathon. Here's how it came together.

The idea was simple: user picks a destination country and visa purpose, Gemini generates the document checklist, and the user tracks their progress in a clean UI. Pro users get access to a conversational AI advisor that answers questions specific to their application.
