About me

Roman Resenchuk

Since 2011, I've been building applications for Apple platforms, both independently and as part of teams, including technical leadership and mentoring. I work with a modern native stack: Swift (SwiftUI, UIKit, AppKit, Combine, Concurrency), having started with Objective‑C.

As soon as AI coding agents appeared, I went all in on agentic development. I build my own harnesses around Claude Code, Codex and Gemini: rules, skills, subagents, MCP servers and automations that plan, write, review and ship code, so one engineer delivers like a team.

Attended Apple WWDC in 2018 and 2019, and regularly join local meetups. In my spare time, I ship my own apps - full cycle from idea to release, including design, development, UI/UX, and ASO.

Working with me, you’ll get:

  • – reliability and on-time delivery
  • – professional communication
  • – efficiency and alignment with requirements

What I build

I design and build native apps for every Apple platform and AI agents that do real work. Swift and SwiftUI on the device, agents and automations around it, and complete product delivery from concept to App Store release.

Mac apps

Mac apps of any scale, from light utilities to complex products, with AppKit and SwiftUI.

Mobile apps

iPhone, iPad and Apple Watch apps, widgets and subscriptions.

AI agents

Agents and automations that write code, review and ship.
