iOS and web · idea to launch
Your idea, built and shipped
You have an idea for software that should exist. I'm Ivan Tse: I learn your business, figure out what to build, design how it works, and write the code that ships it.
Teams I've built for
What I build
iOS apps
Native apps for iPhone and iPad, from prototype to App Store.
Web apps
Software your customers use in the browser, and the API and infrastructure behind it, built to hold up when they show up.
An existing product
Stalled or outgrown its first developer? I pick it up, steady it, and move it forward.
Fractional work
A set number of hours each week on a monthly retainer, owning the mobile side of your product or building alongside your team.
Not sure which you need? Choosing the platform is part of the work. Here's how a project goes, from first call to launch.
How I work
I think like your user
Teams deep in their own product stop seeing it the way a new person does. I look from the outside in, and when a flow won't make sense to a real user I say so.
I make it solid and measurable
Software that holds up when real customers arrive, with the testing to prove it and tracking built in, so you decide from real numbers.
I build with AI agents
AI coding agents like Claude Code help me move fast, and I review and test every line myself before it reaches your customers.
I keep your work confidential
When a project needs to stay in-house, I run the AI on local LLMs on my own hardware instead of sending your data to third-party services.
What I’ve delivered
Sonato iOS app
From 2022 to 2026 I designed and built the iOS app for this hospitality platform serving private member clubs, every feature members use today, including the Apple Wallet pass they tap to get into their club. It holds a 5-star App Store rating across 250+ ratings.
mycharity: water
For charity: water, I built the platform that proved social fundraising. In its first two months it raised $500,000 and brought clean water to 25,000 people; within two years, more than 10,000 fundraisers had raised over $11 million, 70% of all charity: water fundraising.
My own apps
As an indie dev I've taken products from nothing to shipped: Little Memory, a diary app Apple featured as a Staff Favorite, and Ready Time, a planning app. Idea to App Store.
Also: Bebo's mobile site, grown to 4 million daily users; the system that feeds live streams into Twitch's search; web and iOS consulting for the LOOKBOOK fashion community; and the Hipmunk travel app. I've been building and shipping software since 2005.
Testimonials
Ivan is a fantastic product developer who can take wireframe ideas and build an entire product. Not only will the engineering be solid but you will find that the UI/UX is thoughtful, effective, and visually pleasing. People that take pride in their work build better things and that's Ivan.
Ivan is super smart, personable, and great to work with. He's thoughtful and always out to learn new things while staying pragmatic at heart. I'll work with him any chance I can get and you should too.
As head of mobile at Bebo, he was a key player in the rapid construction of a startup that would sell for nearly a billion. I would gladly welcome the opportunity to work with Ivan in the future and highly recommend him for the most demanding roles in the industry.
Ivan's contributions to Magic streamlined our engineering processes and increased the reliability of our mobile and backend software. An excellent engineer. Ivan is able to communicate and implement solutions that directly support business, user, and team needs.
