01Start here
Run an agency? I can be your development team: white-label or referral, fixed quotes.
02The Launch Check
Lovable, Bolt, Cursor, Replit, v0 or a freelancer's half-finished repo. I go through the code and the live app and send you a written report and a short video: what's risky, what will break with real users, and a fixed price to finish it.

What I check
If I don't find anything worth fixing, you don't pay.
03Work
Designed, built and launched end to end, for clients and for myself. Two are live in the App Store with real subscriptions and in-app purchases.
a.k.a. The Vault Job
A full-stack personal wealth platform for tracking net worth across bank accounts, investments, real estate, and collectibles in one place. Live account aggregation through Plaid, subscription billing, and one-click personal financial statement exports.
Charges
a.k.a. The Party Crasher
A shared disposable camera for events. Guests scan a QR to join, shoot a limited roll, and nobody sees a single photo until the host reveals them all together. Seven live party games, in-app purchases, an App Clip for no-install joining, and a web gallery.
Charges
a.k.a. The Fence
A local marketplace built for fast, modern browsing: stronger trust signals, a quicker offer flow, and a dedicated home for yard sales, estate sales, and weekend pop-ups. App-like on the web.
Charges
a.k.a. The Social Club
A social discovery app for finding like-minded friends nearby through shared interests, compatibility, location-aware matching, messaging, and event planning.
Charges
a.k.a. The Inside Job
Website for a virtual executive assistant service for founders and growing businesses. Presents the assistant and recruitment services and leads visitors to book a free discovery call.

04Services
Pick one, pick several. We're a small crew that covers the whole job, from the first sketch to the last App Store screenshot.
iOS and Android apps in React Native and Expo. App Store launches, in-app purchases, App Clips, push notifications, the works.
Next.js products with real complexity underneath: dashboards, marketplaces, SaaS and fintech with live data that stays fast.
Flows, UI systems and clickable prototypes, designed by the same people who'll actually build them. Nothing lost in handoff.
Supabase, Postgres, NestJS, Plaid, payments and subscriptions. The unglamorous stuff that makes the magic trick work.
Got an idea and a deadline? We'll get a real, shippable first version into real users' hands. No throwaway prototype.
Inherited a tangled app? We'll untangle it, speed it up, sand down the UI and get it shipping again.
05How I use AI
Yes, I use AI too: it writes a lot of my first drafts. My job is the part it can't own: deciding what to build, checking every line that touches money or personal data, and being accountable when it ships.
06Pricing
From a single fix to a whole app. Every job gets a firm quote before work starts, so you know the full price up front.
1–5 days
From $350
Something small needs changing on an app or site you already have.
1–2 weeks
From $1,500
You need a clean, fast website to look the part.
1–3 weeks
From $2,500
You built it with AI or a freelancer and it's stuck.
2–3 weeks
From $3,500
Your business deserves a website that brings in enquiries.
6–8 weeks
From $12,000
You have an idea and need a real first version.
8–12 weeks
From $18,000
You need an iPhone or Android app in the stores.
After launch: monitoring, updates and small fixes, so the app keeps working while you grow it. Cancel anytime.
Smaller job, or not sure where yours fits? Ask anyway. If it's not worth hiring me for, I'll tell you.
07How it works
Every good job has a plan. Here's how an idea goes from “what if…” to live in people's pockets: usually 6–12 weeks for a new product, 1–3 for a rescue.
Week 1
We dig into the idea, the users and the goal: what's the loot, who's guarding it, what does winning look like? You leave with a plan and a fixed price, not a guess.
Week 2
Flows, wireframes and a UI with actual personality. You click through a real prototype before a single line of production code.
The sprint
Short build cycles with a live preview link from day one and a demo every Friday. No black boxes, no surprise invoices.
Launch & beyond
App Store submission, launch and 30 days of fixes included. I don't vanish when the sirens start; I stick around to make v2 even better.
08About
I'm Simon. I finish, fix and launch web and mobile apps: logins, payments, data and App Store review included. Fixed price, a demo every week, and you work with me from first call to launch.
No account managers and no handoffs: the person on the call is the person writing the code. That means faster decisions, fewer meetings and software that feels alive rather than polite, beige and forgettable. If I'm not the right fit for your project, I'll tell you who is.
Weapons of choice
The ringleader
Simon Riley
Founder and engineer. Years building web and mobile products with dense data, live state and workflows people depend on. Into cars, grew up on motocross bikes, currently plotting a kitesurfing habit.
09FAQ
Often, yes: for a prototype, a landing page or an internal tool, you should. Once your app takes payments, stores personal data, needs to pass App Store review or has people relying on it, a hidden mistake costs more than an engineer does. Many clients come to me with something they started in Lovable or Cursor, and we keep what's good.
Small changes to an app or site you already have start at $350, and a starter website at $1,500. A Launch Check is $490, finishing an AI-built app starts at $2,500, a web MVP at $12,000 and a mobile app at $18,000. Every job gets a fixed quote before work starts, so the price doesn't move unless you change the scope.
Yes. Everything lives in your own accounts and repository from day one, and all the code and rights are yours once the final payment is made.
Small tweaks are part of the job. Bigger new ideas get a short written note with the price and timeline impact, and nothing changes until you approve it.
Not at all; most of my clients aren't. I explain decisions in plain English, you get a demo every Friday, and you'll always know what's done and what's next.
You get 30 days of fixes included. After that, an optional Care Plan from $450 a month covers monitoring, updates and small changes.

Or just an idea. Tell me what you're building and I'll reply within one working day, usually with questions, sometimes with sketches.
