I build production iOS and macOS apps for startups and small teams. I focus on AI-native apps that run on the device. That means fast responses, lower cloud cost, and better privacy for your users.

On-device AI
Real systems delivered in production. From complex business platforms to developer tooling.
I work with specific types of teams and projects. Clear fit means better outcomes.
Fixed-scope services with clear outputs, clear timelines, and senior-level execution.
We review your app and show what to fix first. You get a clear roadmap, AI readiness notes, and practical next steps. Think of it like a structural survey before a renovation.

5 business days · Async-first, one live session
→ Prioritized technical roadmap
We build the first production version of your app in one focused sprint. You get a strong SwiftUI foundation, data sync, and an App Store-ready build. Think of it like building the frame of a house before adding rooms.

6–8 weeks · Sprint-based, async collaboration
→ App Store-ready iOS/iPadOS app
We add private, on-device AI to real products. Models run locally, so your app stays fast and user data stays on the device. Think of it as hiring a smart assistant that never sends notes to an outside server.

B2B Operations Platform · iOS & iPadOS
Problem
Business owners running operations through messaging threads, paper trails, and approval bottlenecks. Decisions wait. Owners pay for tools their teams don't even own.
System
Owner-controlled CloudKit architecture. The owner holds the data and the subscription — team members join free under role-based permissions. Built on an ISO 27001-aligned operations model covering warehouse, sales, and dispatch.
Outcome
Approvals and team communication move from days to minutes. Paper-based bureaucracy disappears. The owner keeps control of every record on their private iCloud.
Document Intelligence · iPhone, iPad, Mac
Problem
You have a 40-page contract, a stack of meeting notes, or a research paper you don't have time for. Pasting them into ChatGPT means leaking your private documents to a third party. Reading them line-by-line means losing the day.
System
A smart extraction engine that works on any document, with purpose-built schemas for six common types. Powered by Apple's 3-billion-parameter on-device Foundation Models. Documents never leave the device.
Outcome
Drop in any document. Ask deeper questions. Get a layered summary instead of a one-paragraph skim. Compare two documents side-by-side. Without your data ever touching a server.
Offline AI Assistant · iOS · Free
Problem
Most AI assistants stop working the moment your signal drops. In remote areas, on long flights, in places where connectivity is unreliable — the assistants people most need become useless.
System
A custom-tuned local model called Echo, downloaded once during install. Runs entirely on the device with no internet required afterward. Specialized for survival, first aid, water sourcing, shelter, and fire.
Outcome
A pocket assistant that works in the backcountry, on the plane, in the cabin, in any place a signal doesn't reach. Faster responses, better battery, and the only data leaving your device is the one-time model download.
“3NSOFTS consolidated three disconnected tools into one iOS workflow and cut our coordination overhead by 65% in the first month.”
“Their architecture and tooling recommendations now save our team 4 to 6 engineering hours every time Xcode breaks a build pipeline.”
“The on-device AI architecture gave us 0-byte external data transfer and extended battery life by 40% for emergency use cases.”
Industry Context
“Apple Intelligence is the personal intelligence system for iPhone, iPad, and Mac. It draws on your personal context to give you intelligence that's most helpful and relevant to you. Privacy protections are built in from the ground up.”
3NSOFTS builds production apps on this exact infrastructure. We use Apple Foundation Models, Core ML, and Apple Intelligence to ship AI features that run without a cloud connection.
Why teams choose 3NSOFTS when they need reliable systems, not quick demos.
Your app works even when signal drops. Data saves locally first, then syncs in the background.
We run AI on the device, not in the cloud. That keeps features fast and private.
We build SwiftUI code that scales beyond a prototype. Teams can add features without rewrites.
We optimize for the next 12 months, not only for launch week.
