Fractional CTO · Available Now

Your Startup's CTO.
One Person. Full Ownership.

I embed as your technical lead, owning architecture, development, and delivery end-to-end. Whether you're building from zero or scaling an existing product, I work as a senior engineer who ships, powered by Claude and Cursor.

You need technical leadership.
The usual options are broken.

Whether you're a pre-seed startup with no technical co-founder, or an established company that needs a senior engineer to own a product. Hiring full-time is slow and expensive, and agencies ship code you can't maintain. There's a better way.

Full technical ownership,
from day one

I don't consult and hand you a deck. I embed as your CTO, setting the technical vision, building the product, and owning the outcome.

Product Development

New build or existing product. I own development end-to-end. Web app, mobile app, backend, and infra, using Claude and Cursor to move at a pace traditional teams can't match.

  • Full-stack web & mobile development
  • Backend APIs & cloud infra
  • CI/CD, monitoring, App Store deployment
  • Docs & test coverage for clean handoff

AI-Native Development

I build AI into the product, not on top of it. LLM integrations, AI agents, RAG systems, and workflow automation, implemented properly and not bolted on as an afterthought.

  • Claude / GPT / Gemini integration
  • Custom AI agent development
  • RAG & vector database systems
  • AI workflow automation

Ongoing Technical Leadership

Monthly retainer. I stay embedded as your technical lead, keeping the quality bar high and the architecture coherent as your team grows. You get senior-level judgment on every decision without the full-time overhead.

  • Code reviews & technical mentorship
  • Documentation & testing for seamless handoff
  • Hiring support for future engineers

Technical Due Diligence & Audits

Inheriting a codebase? Raising a round? I audit your technical stack (architecture, security, scalability, and team) and give you a plain-language report with a remediation plan.

  • Codebase health & architecture review
  • Security & scalability assessment
  • Pre-fundraise technical readiness

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
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
