    SnapSend - Zero-Knowledge Secret Sharing

    SnapSend is a zero-knowledge secret-sharing app, share a password, API key, or note that destroys itself after it’s read.

    🔗 Live app: https://www.twine.net/signin

    How it works

    The secret is encrypted in your browser with AES-256-GCM before anything ever touches the network. The decryption key lives only in the URL fragment (after the #), so it’s never transmitted to or stored by the server, the server only ever holds ciphertext it can’t read.

    Key features

    • Zero-knowledge encryption - AES-256-GCM performed client-side; the server never sees plaintext or the key
    • Burn after reading - the secret is destroyed atomically after the last allowed view, with no race conditions or leftovers
    • Auto-expiry - configurable TTL (5 minutes to 1 week) removes the secret even if the link is never opened
    • View limits - set a max number of views before the link self-destructs

    Tech stack

    • Frontend: Next.js, TypeScript
    • Backend: .NET 10
    • Storage: Redis (TTL-native, ephemeral by design)

    Why I built it

    Most “secure” paste/share tools still trust the server with your plaintext at some point. SnapSend moves encryption entirely to the client, so even a compromised or subpoenaed server has nothing readable to hand over.

    Vitalink - AI-Powered Healthcare Platform

    Vitalink is a healthcare platform that helps patients find the right doctor and manage their care, all in one place.

    🔗 Live app: https://www.twine.net/signin

    Key features

    • AI doctor matching - describe your symptoms in plain language and get matched to the right specialist in seconds
    • Book in seconds - pick a doctor, choose a time, and confirm an appointment without back-and-forth calls or forms
    • All your care, one place - appointments, doctors, and visit history live together instead of being scattered across apps and portals

    Tech stack

    • Frontend: Next.js, React, TypeScript
    • Backend: .NET 10
    • Database: PostgreSQL, Entity Framework Core
    • Hosting/Infra: Azure

    Why I built it

    Booking and managing healthcare is still full of friction, phone tag, scattered records, and guessing which specialist you actually need. Vitalink puts symptom-based doctor matching, booking, and visit history behind one clean interface, so patients spend less time navigating the system and more time getting care.
