Independent Software Studio

Small software,precisely made.

We're LeeJay Soft — an independent studio designing and shipping focused products across macOS, the web, and AI. Fewer features, sharper decisions, built to last longer than the trend that inspired them.

About

One studio, end to end.

LeeJay Soft is an independent software studio. Every project is designed, built, and shipped by the same hands — from the first sketch to the App Store listing, with no handoffs in between.

We work across a deliberately wide range — a native macOS app, a local-first AI gateway, real-time financial charts, self-running content pipelines — because the interesting problems rarely respect a single stack. What stays constant is the approach: understand the real job, cut everything that doesn't serve it, and hold the same bar in the code as in the interface.

We like shipping. Ideas are cheap; a product that's live on the App Store, deployed to the web, or running on a schedule while we sleep is the only proof that counts. Most of the work below is running in the real world right now.

Services

01
Native App Development
macOS and iOS apps in Swift and SwiftUI — from first prototype to App Store release, StoreKit, and everything in between.
02
Web Apps & Interfaces
Fast, considered front ends in React, TypeScript, and vanilla JS — real-time data, rich interaction, and no unnecessary framework weight.
03
AI Systems & Agents
LLM-powered products and agent pipelines — multi-channel gateways, tool routing, and using models as workers, not just chat boxes.
04
Automation & Tooling
Self-running pipelines and developer tooling that quietly do the repetitive work — scheduled, config-driven, and cheap to operate.
