Mzed Studio — Hire an MVP Developer for Your SaaS

A single senior operator who designs, builds, and ships production-grade software, from first commit to deployed product. For founders who need a SaaS developer for hire: MVPs in Next.js and TypeScript, codebase rebuilds, and senior development throughput by the week.

    Software in the browser that customers sign up for and pay for.

  • Mobile apps

    One product across iPhone, Android, and the web.

Process

Day 0: Discovery

A 30-minute call. You walk me through the product, the users, and the moment you're stuck on. I listen, ask the hard questions, and tell you if we're a fit.

Day 1–2: Scope & Proposal

I break the work into clear deliverables with honest timelines. You get a proposal that names exactly what you're paying for.

Day 2: Contract & Kickoff

Most engagements move from discovery to signed contract inside 48 hours. Repo on your GitHub, infra on your accounts.

Day 3+: Design & Build

Design and engineering happen at the same time. You see working software early and often.

MVP Pricing — How Much Does an MVP Cost?

One question. We show you the one engagement that fits, price up front. MVP development from $5,000 fixed for a 2–4 week build. Codebase audits $2,500 fixed. Weekly SaaS development $2,500 per week, pause anytime.

MVP — From $5,000

A live product, in weeks not months.

2–4 weeks · Fixed scope

Best for: For a new idea that needs a first version in front of customers. Scope is agreed within 48 hours.

  • A plan and fixed scope agreed within 48 hours
  • A website, a phone app, or both, designed and built
  • User logins, payments, and the main features set up
  • Put live on accounts you own
  • 2 weeks of support after launch

Rebuild — $2,500

Stop fighting the codebase.

1-week audit · fixed

then $2,500 / week — Rebuild scoped per phase

Best for: For a live app that has become fragile, slow, or hard to change. A full audit comes before any rebuild quote.

  • Codebase, infra, and on-call audit
  • Written report and rebuild plan, yours to keep either way
  • We work incrementally, so no big-bang rewrite and no downtime
  • Weekly work after that, scope agreed per phase
  • Pause or escalate after each phase

Scale-up — $2,500 / week

Senior throughput, by the week.

Ongoing, pause anytime

Best for: For a live app that needs an experienced builder week by week: new features, speed, and reliability.

  • Weekly scope, agreed each Monday
  • Feature work on your live product
  • Performance, observability, infra hardening
  • Pause or cancel any week
  • No retainers, no auto-renewal

FAQ

How fast can you ship an MVP?
Most MVPs ship in 2–4 weeks, so you're testing with real users instead of guessing.
What does a typical engagement look like?
Discovery call → scope & proposal → sign contract → start building. Design and development happen at the same time, so there's something to click through early.
Do you handle design, or just development?
Both. No wireframes sitting in Figma for weeks; you get a working product that looks and feels right from day one.
What happens after launch?
It depends. Some founders need ongoing support — scaling, new features, infrastructure. Others are good to run on their own. Either is fine.
Can you pick up an existing codebase?
Yes. Whether it's a prototype that needs to become production-ready or a live product that needs new features, I pick up where things left off.
What stack do you build on?
Usually TypeScript, React, Convex or Postgres, Stripe, and Cloudflare or Vercel, with Expo for mobile and Swift or Rust for native apps. The final stack gets picked for your product.
