You’re hiring for one of two roles. A senior design engineer who can really build, or a staff full-stack engineer with actual taste. Most searches end in a compromise on one half. Scroll back up. Every screen you just passed, I designed and built myself, and I’ve been shipping both halves since 2013.

Here’s what that looks like on your team:

• One desk, zero handoffs. The Figma file and the production code have the same author, across front end, backend and smart contracts, so what you approve is exactly what ships.
• Native mobile, properly. kankan.camera scans rooms in 3D with iPhone LiDAR and holds a compass to true north through real walls, in native Swift at App Store quality.
• Payments proven in production. Cross-chain checkout live on mainnet, onchain payouts automated end to end. This is where my last few years went.
• AI that reached real users. I built a visual LLM-pipeline builder before “AI agent builder” was a category name.
• Products people stay in. I hold the UX to the same bar as the architecture, so when your users open what we ship, they stay.

I’ve watched the stack turn over, from Flash to HTML5, Windows Phone to modern mobile, monoliths to mainnet, and I still pick the boring option your team can maintain five years from now. If your role needs both halves, message me on Telegram below and tell me what you’re building.
