Projects

What I've built

archerbytes.tsx

ArcherBytes

Full-stack platform

Backend architecture and CMS for a knowledge-sharing platform serving 20,000+ DLSU students. REST APIs and PostgreSQL schemas built with Drizzle ORM power articles, comment threads, and reactions, with Google sign-in through Better Auth.

resole.tsx

ReSole

Mobile / AI marketplace

in dev

An AI-powered peer-to-peer marketplace that predicts fair prices for shoe listings and nudges owners to donate to charity after 30 days unsold. Built with React Native (Expo), backed by a TensorFlow-trained LLM — YOLOv8 Nano for shoe detection, Gemini 2.5 Flash and EfficientNet Lite for condition grading.

vibe-coded-website-fuzzer.tsx

Vibe-Coded Website Fuzzer

Security tooling

in dev

A hybrid security scanner and fuzzer for auditing "vibe-coded" apps — code shipped fast via LLMs like ChatGPT or Claude that runs fine but skips real security controls. It scans for hardcoded secrets, missing auth checks, and weak JWT validation, then fuzzes endpoints for IDOR issues, missing rate limits, and leaked stack traces.

animonotes.tsx

AnimoNotes

Study notes platform

A study-resource hub for CCS students at DLSU, built so classmates could actually find and share notes instead of digging through group chats. Next.js and TypeScript up front, Prisma over PostgreSQL in back, with Better Auth locking access to verified students only.
