No agency layers, no junior devs billed as seniors, no open-ended hourly creep. Every project gets a written scope and a fixed price before work begins.

Why hire a freelance app developer?

When you hire through a development agency, a meaningful slice of your budget pays for sales teams, project managers, and office overhead — before a single screen is designed. Hiring a freelance mobile app developer cuts that layer out. You pay for expertise and output, not for a brand name on a proposal.

That does not mean going it alone without structure. A good freelance engagement still has a clear scope, milestone payments, regular demos, and a contract that protects both sides. The difference is speed: when you have a question at 10am, you get an answer from the person writing your code — not a ticket in someone else's queue.

When hiring freelance makes sense

  • You're building an MVP and need to move fast on a defined budget
  • Your in-house team needs a Flutter specialist for a sprint
  • You've been quoted six figures by agencies for a mid-size app
  • You want one accountable person, not a rotating cast of contractors

What you get when you hire me

  • UI/UX design in Figma before development starts
  • Flutter development for iOS and Android from one codebase
  • Weekly progress demos on a real device
  • App Store and Google Play submission support

How to hire a mobile app developer — without regret

The hardest part of hiring an app developer is not finding candidates — it's evaluating them. Portfolios look similar. Everyone claims "clean code" and "on-time delivery." Here is a practical filter that saves most founders months of pain.

First, ask for a fixed-price quote on a written scope, not an hourly estimate. Hourly engagements reward slow work. A scoped quote forces both sides to think through features before money changes hands. Second, talk to the actual developer, not just a sales rep. If you cannot get the person who writes code on a call before signing, expect surprises later. Third, check that they have shipped apps you can download — not just mockups in a Behance portfolio.

I share relevant shipped work on request and walk through my process on a free intro call. If we are not a fit — wrong timeline, wrong tech, wrong budget — I will tell you honestly rather than take a project that will end badly for both of us.

Freelance app developer — engagement models

Most clients hire me for a full project: design through launch, fixed price, milestone payments. Typical structure is 30% to start, 40% at mid-point demo, 30% on delivery and store submission. For larger products we can break milestones into smaller chunks.

I also take on shorter contract work: add a payment flow to an existing app, rebuild a broken onboarding, or join your team for a three-month feature push. Contract rates are available on request after we define the hours or deliverables needed.

Every engagement includes source code ownership transferring to you on final payment, documentation of key architecture decisions, and a handover call so your team can maintain or extend the app after I step off.

Hire an app developer who uses Flutter

When you hire a mobile app developer today, you face a platform choice: build natively for iOS and Android separately, or use a cross-platform framework. I work exclusively in Flutter because it delivers native-quality performance with a single codebase — which means lower cost and faster time to market for most products.

Flutter is not a shortcut around good engineering. It is a mature Google-backed framework used in production by companies worldwide. For MVPs, consumer apps, and internal business tools, it is usually the right call. If your project genuinely needs pure native Swift or Kotlin for a specific reason, I will say so upfront rather than force-fit the wrong tool.

Frequently asked questions

How do I hire you for an app project?

Email [email protected] with a short description of your app idea. I'll reply within one business day with clarifying questions, then send a written scope and fixed-price quote. No commitment until you approve the scope.

Freelance vs agency — what's the difference?

With a freelance app developer you work directly with the person building your app — faster decisions, lower overhead, and no markup for account managers or junior developers billed at senior rates.

Do you sign NDAs and work under contract?

Yes. I routinely work under NDAs, freelance contracts, and milestone-based payment schedules. IP transfers to you on final payment.

Can you join an existing team or codebase?

Yes. I take on contract engagements to extend an existing Flutter or mobile codebase, fix technical debt, or ship a defined feature set alongside your in-house team.
