Project PassGo
- passport services, digitized.

The problem

Passport services depend on long forms, identity documents, scheduled verification, and back-office decisions. The rough edge is not one screen; it is the handoff between citizen submission, document quality, appointment logistics, and administrative review.

The approach

PassGo splits the product into a polished Next.js applicant/admin portal and a NestJS API. The frontend handles guided application and renewal journeys with TanStack Query, Zustand, document upload flows, and email-triggering API routes; the backend owns JWT role access, Mongo-backed workflows, AWS S3 uploads, throttling, and Google Document AI OCR.

Full-stack engineer. Designed and implemented the applicant experience, admin workflows, backend modules, document processing path, and cloud integrations across the paired frontend and backend repositories.

• Applicant portal supports new passport applications, renewals, status tracking, document uploads, and appointment booking.
• Admin workspace covers application queues, appointment handling, status updates, notes, rejection reasons, and reporting surfaces.
• Document pipeline combines AWS S3 storage with Google Document AI OCR for uploaded NIC, birth certificate, passport photo, and supporting files.
• Backend modules cover authentication, users, applications, appointments, renewals, upload services, S3, and role-protected administration.
