From first call to shipped product, fast

1

Strategy Call

30 minutes. We map your vision, your current tech situation, and where you need to be. I tell you exactly what I'd build and in what order.

2

Technical Blueprint

I produce a clear architecture doc, stack recommendation, and delivery timeline. No vague SOWs, no surprises. You know what you're getting before we start.

3

Build & Ship

I own the build end-to-end. You see working software weekly, not slide decks. AI tooling means I move at a pace that would take a team of three.

4

Own & Iterate

You own the code. I stay on as your technical lead, iterating, expanding, and keeping the quality bar high as your startup grows.

Real products.
Real production.

Grant Espanet

Grant Espanet
Founder & CTO

I'm a full-stack engineer and technical leader based in South Florida. I've shipped production software to millions of users, from Samsung Health integrations to App Store releases at scale, and I've been building AI-native products since before it was the obvious thing to do.

MetaShark® is my one-person shop. I use Claude and Cursor not as gimmicks, but as genuine force multipliers that let me write, review, and ship code at a pace that makes solo execution genuinely competitive with small teams.

  • B.S. Computer Science, Florida Atlantic University
  • Architected software integrated directly into the Samsung Health App
  • Contributed to the August Home iOS app & SDK (millions of downloads)
  • Led all development and App Store releases for ApparelMagic Mobile
  • Shipped iOS, Android, web, and backend systems across a dozen industries
