Mykola Rudenko

I'm a senior iOS developer with 9 years shipping production Swift apps — from a UK bank's Open Banking platform used by millions of customers to a US startup's iOS app I built solo, end to end, from idea to TestFlight beta.

What I do for clients:

- Build iOS apps end-to-end: architecture, Swift/SwiftUI development, testing, App Store release

- Modernize existing codebases: modular architecture (SPM, Tuist), Swift 6 concurrency migration, test coverage, refactoring legacy UIKit

- Set up delivery infrastructure: CI/CD pipelines (Fastlane, GitHub Actions, GitLab CI), release automation, quality gates

- Integrate AI features (OpenAI API, Google Vertex AI) and set up AI-assisted delivery workflows that speed up development without lowering the quality bar — I'm a certified Claude Architect (Anthropic, CCA-F)

How I work: I've spent 5+ years embedded in enterprise client teams (banking, retail) as an external engineer, so I integrate quickly, communicate clearly with non-technical stakeholders, and can own a scope independently or lead a small squad — I've led teams of up to 5 developers and hold a high engineering bar (certified technical interviewer, 80+ interviews).

Recent results: cut a banking client's testing time 60% with an AI-assisted automation tool; halved CI/CD execution time for a national retailer while moving the team to a 2-week release cycle; sustained a 98–99% crash-free rate in production.
