Sound
familiar?

What business owners tell me before an app build.

01

“Your customers expect an app, and you don’t have one.”

Competitors are on your customers’ phones, and you’re still relying on a website and social posts.

02

“Agencies quoted you, but you’d never talk to the person building it.”

You want a direct line to the developer, not a project manager relaying messages.

03

“You’re not sure whether you need iPhone, Android or both.”

You need a clear recommendation based on your customers and budget.

04

“Your current app is slow, outdated or getting bad reviews.”

You need someone who can fix it or rebuild it properly.

You work with
the builder.

No agency handoff. Speak directly with the developer building your product.

Christopher Walsh, senior full-stack developer in Toronto

You talk directly to the Toronto developer building your app — not a project manager relaying messages.

6 years across the full stack — mobile (iOS/Android), web, backend, cloud and AI — including deploying and maintaining production apps and databases for 1.1M+ active users. That means fewer handoffs, faster decisions and one person accountable for the result.

Clear from
day one.

Start with the business goal, define the right build, then move through launch without unnecessary complexity.

01

Strategy

Define the users, core features and whether to start on iPhone, Android or both.

02

Architecture

Choose native or cross-platform, plan the backend and map App Store requirements.

03

Build

Test builds on your own phone throughout, with direct feedback loops.

04

Launch

App Store and Google Play submission, release support and the next update.

$20K+

Typical mobile app projects start at $20K+. Where your app lands depends on platforms, features and the backend behind it. A focused first release keeps the starting point lean; separate native apps and real-time features add to it.

Moves it up the range

  • Separate native iOS and Android apps
  • Subscriptions, payments or marketplace logic
  • Real-time features, maps or chat
  • A custom backend and admin dashboard

Keeps it lean

  • One platform or cross-platform first
  • A focused first release
  • Existing design and brand assets
  • Proven services for login, payments and notifications

Straight
answers.

The questions people ask before booking a call.

How long does a typical project take?

It depends on platforms and features. After the strategy call you get a timeline tied to a defined first-release feature list, including time for App Store and Google Play review.

How fast can we start?

Quickly. Book a strategy call and we can usually talk within a few days. If we’re a fit, you get a written scope and estimate shortly after, and work starts as soon as you approve it — no long sales process.

Do I need an iPhone app, an Android app, or both?

It depends on your customers. Cross-platform with React Native reaches both from one codebase; native makes sense when you need maximum performance or platform-specific features. We decide this on the strategy call.

Do you handle App Store submission?

Yes. I handle App Store and Google Play submission, store listing requirements and release, and work through any review feedback with you.

Do I own the code?

Yes. You own the code and the repository, and accounts are set up in your name. You are never locked in to working with me.

How do we work together day to day?

You work directly with me — no account manager and no agency handoff. You get regular progress updates, working builds to review, and quick answers when decisions come up.

What if I only need a small feature, not a full platform?

That’s fine — not every project is a full build. A single feature, an integration, a fix or a review of existing code can be scoped and quoted on its own. The strategy call is free either way, so it costs nothing to ask.

Do you sign NDAs?

Yes. I’m happy to sign your NDA before you share details — send it over before or after booking. Your idea and information are kept confidential either way.

What does something like this cost?

Typical mobile app projects start at $20K. Platforms, payments, real-time features and the backend are the biggest drivers. You get a clear estimate after the strategy call.
