Things I've Built

An automated n8n pipeline that scrapes 10 AI/ML/tech RSS feeds and publishes a daily digest to GitHub Gist without manual intervention. Deployed on a self-managed DigitalOcean VM with a custom domain and SSL, running on a daily schedule. A Next.js frontend on Vercel presents the digest in a readable format.

An AI-powered conversational travel-planning avatar for Sri Lanka trip planning, built within a 24-hour buildathon for the "Beyond Presence" track at Cursor Colombo 24H Buildathon. Implemented an n8n-based workflow (self-hosted on DigitalOcean) that captured leads, triggered the conversational agent, and auto-sent trip summary emails to clients and organizers.

A premium, zero-knowledge password manager and secret vault built with Next.js 16, React 19, and Supabase. Passwords, API keys, secure notes, and cards are encrypted entirely in the browser using AES-256-GCM via the Web Crypto API — the server only ever sees ciphertext. Features a dual password system (account + master), TOTP 2FA, a cryptographically random password generator, vault search/filter/favorites, clipboard auto-clear, and Supabase row-level security.

A kernel-level memory protection and logging framework for xv6-riscv that intercepts illegal memory accesses via trap handling. Classifies fault regions (null dereference, unmapped memory, buffer overflows) and logs structured fault data in a circular kernel buffer. Exposes fault logs to user space through a custom system call (memlog) and ensures only the faulty process is terminated, keeping the rest of the system stable.
