Lumen Health — Figma to App Store in 11 weeks

Challenge

Lumen needed a HIPAA-grade telehealth iOS + Android app — and a launch tied to a Series B announcement.

Solution

Two parallel native squads (Swift, Kotlin) shared a TypeScript spec for the API, with weekly TestFlight + Play Beta drops. Encrypted video on WebRTC + Twilio fallback.

Finovate — rebuilding a trading platform in 90 days

Challenge

A legacy Java monolith struggled past 100k concurrent traders. Latency spikes were costing trades, and shipping a new feature took quarters.

Solution

We rebuilt the platform on a real-time React + Node stack with event sourcing, Redis streams, and a Cloudflare Workers edge tier. A traffic-shadowing migration enabled a zero-downtime cutover.
