We turn ideas into custom web and mobile apps — engineered end to end by one builder, from first commit to production.
Web apps, mobile apps, internal tools — the systems a business actually runs on. One engineer from first commit to production, accountable for every line.
Sole proprietor. Lean by design. No account managers, no handoffs, no layers between you and the code.
A conversation about what you're actually solving — not a sales call. If we're not the right fit, you'll hear it before anyone signs.
Working software in weeks, not slide decks in months. Progress you can run and test, not a reveal at the end.
Shipping is the start, not the finish. Maintenance, iteration, and the long tail are part of the engagement.
I'm Ian, founder of Horizon Code — and the engineer behind everything it ships. Most recently Principal Engineer at GXBank, Grab's digital bank in Malaysia, across payments, rewards, and fintrust. Before that, app performance at Shopee. Native mobile is the core craft — Kotlin and Swift — backed by the web and backend a full product needs.
Production-grade engineering that holds up in the real world. Big-company rigor, at small-shop speed.
