Yashal Najeeb

Full-Stack Product Engineer · iOS, React Native, TypeScript, Postgres

I take products from zero to the App Store — most recently a provenance platform now holding $10M+ in luxury assets, and a five-repo HIPAA platform I rescued as its sole engineer.

chauffeur

Lets coding agents drive the iOS Simulator — and tells them the truth.

Agents tap a disabled button and report “done.” chauffeur hands the agent the screen as an outline it can reason about, taps through the Simulator’s own input system, and verifies every action against what actually changed: NO EFFECT, INTERCEPTED or APP CRASHED, with the line that caused it.

180-run benchmark vs Xcode 27’s MCP: under half the turns at ~1/6 the cost, 45/45 tasks verified on Opus.

Myne Global

Provenance for luxury goods, from purchase to resale.

Built end to end as lead engineer: SvelteKit API, Postgres with row-level security, a SwiftUI app and Stripe/StoreKit billing. Owner-held-key encryption carries every ownership transfer, dealers issue Myne Passports at the point of sale, and every buyer search checks a registry of 16,830 stolen-item records.

$10M+ in registered assets · 400 collectors · 12 NYC dealers

Mobile MRI/CT viewer

Healthcare records platform (contract).

Clinicians couldn’t view scans on mobile: the platform’s legacy imaging viewer predated touch support. Instead of a risky framework upgrade, I built a modern Cornerstone3D renderer inside a WebView and moved every control — slice scrubber, series, window/level, pan, pinch-zoom — into native React Native over a small message bridge. Also rebuilt authorization across 156 API routes and stood up the first iOS release path.

Hard Pills to Swallow

A pop-art blog its writer runs entirely herself.

Public site plus a full admin: TipTap editor with autosave and scheduling, banner styling, SEO panel, media library and mailing list. Database triggers make “publish now” and scheduled posts behave the same — the email goes out once and the post auto-shares to X and Threads.
