Aksara is a full-stack blog platform where readers browse, comment on, and rate articles, while writers manage content through a role-gated dashboard (User/Author/Admin) built around a TipTap rich text editor. The backend enforces XSS-safe HTML sanitization on all user-generated content, HttpOnly refresh-token + short-lived JWT authentication, Redis-backed rate limiting, and OTP email verification, with a BullMQ worker dispatching newsletter emails on every new publish. Designed, built, and security-tested solo end-to-end — including manual XSS, auth-enumeration, and session-handling audits via Postman.

Spectra is an augmented reality (AR) learning application designed to help children with Autism Spectrum Disorder (ASD) practice object recognition in an interactive, low-friction way. The app overlays 3D learning objects onto the real-world environment through the device's camera, allowing children to explore and engage with educational content in a more visual and hands-on manner than traditional learning methods. The project was developed as part of an undergraduate thesis, with a strong focus on improving the stability and reliability of AR object tracking so that the learning experience stays smooth and distraction-free for young users.

The backend provides services for user registration and login, as well as handling and managing application data through a structured architecture consisting of controllers, models, routes, and middleware. The API is deployed using Vercel to provide backend services for the CineView Android application.
