Built Authify — a full-stack authentication system that goes beyond a basic login form. It handles everything a real production app needs: JWT access and refresh token rotation, email verification, password reset flows, multi-device session tracking, and background email queues using BullMQ and Redis.
The backend is Node.js + Express + TypeScript with PostgreSQL through Prisma. Security wasn't an afterthought — HTTP-only cookies, Argon2 password hashing, rate limiting, and Helmet headers are all in place. The frontend is React + TypeScript with TanStack Query handling server state.
Most auth tutorials show you the happy path. This one handles the edge cases — token expiry, brute-force protection, emails that don't block the request cycle, sessions you can actually revoke per device.
Built it as a reference system I can drop into client projects or extend with OAuth and 2FA.

I spent over a year as the product designer for Hypernative. They just raised $40M in Series B funding not long ago.
Hypernative is a real time security platform for Web3, protecting billions in assets across 60+ blockchains. The product is genuinely best in class. But when I started, the UX wasn't matching the tech.
The UI was super complex, data heavy, and required a steep learning curve. For a security platform where seconds matter, that's a big problem. If your users can't parse a critical alert instantly, the best detection engine in the world doesn't help.
So We rebuilt the experience around three pillars: clarity, actionability, and scalability.
Clarity meant redesigning the threat severity system so users could gauge urgency at a glance. Actionability meant replacing static alerts with interactive ones that included recommendations, historical context, and mitigation steps right in the UI. Scalability meant building a modular dashboard so different teams could customize the interface for their workflow.
The results were 40% improvement in threat detection response time. 30% increase in user retention. 25% reduction in false positive friction.
In complex B2B products, design is the difference between a tool people tolerate and a platform they rely on. Especially in security so if the UX creates cognitive load at the moment someone needs to act fast, you've already lost.
Perfect design

great work
Built a full eVTOL air taxi cockpit + passenger HMI with @rive_app.
Oh—and I never opened the Rive editor. Every .riv file was generated from natural language with an agent writing typescript into a custom binary compiler.
First of its kind.
