About me

Roman Resenchuk

iOS and macOS developer and agentic AI developer. I build native Swift and SwiftUI apps, plus agent harnesses, autonomous agents and MCP integrations. Open for projects and senior roles.

Building for Apple platforms since 2011, solo and in teams, including technical leadership and mentoring. Stack: Swift (SwiftUI, UIKit, AppKit, Concurrency), started with Objective‑C.

Since AI coding agents appeared, I build my own harnesses around them: rules, skills, subagents, MCP servers and automations that plan, write, review and ship code, so one engineer delivers like a team.

Attended Apple WWDC 2018 and 2019 and join local meetups. I also ship my own apps end to end: design, development, UI/UX and ASO.

Working with me, you get:

  • on-time delivery
  • professional communication
  • work that matches the requirements

I build native apps for every Apple platform: iPhone, iPad, Mac and Apple Watch, from concept to App Store release. Beyond apps, I do agentic AI development: agent harnesses, autonomous agents and MCP tools.

Mac apps

Mac apps of any scale, from utilities to complex products.

Mobile apps

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

AI agents

Agent harnesses, autonomous agents and MCP tools.
