Senior full‑stack iOS engineer (Swift/SwiftUI/UIKit) who can ship the mobile app + the backend end‑to‑end (Node.js + TypeScript). If you have an existing app that needs to scale, stabilize, or move faster, I can step in, quickly get context, and start delivering. What I do best • iOS/iPadOS/macOS development in Swift (SwiftUI + UIKit) • API design + implementation (Node.js/TypeScript), Firebase, REST/GraphQL integrations • Architecture & codebase health: MVVM, DI, modularization, testing • Performance & reliability: profiling, crash fixes, memory leaks, smooth UI • Legacy modernization: UIKit → SwiftUI, Objective‑C → Swift Typical engagements 1) Audit (3–5 days, fixed price): quick assessment + prioritized plan + first fixes 2) Stabilization/feature sprint (1–2 weeks, fixed): ship milestones, unblock releases 3) Ongoing retainer (monthly): predictable delivery cadence + support Recent outcomes ✓ Built apps with 100k+ monthly active users ✓ Helped startups gain early adopters via MVP + TestFlight ✓ Modernized legacy codebases and improved performance/stability If you share your repo/API constraints and your top 1–2 goals for the next 2 weeks, I’ll propose a tight plan with milestones.

Senior iOS developer. 10,000+ hours and 73 projects delivered on Upwork. I build and maintain production Swift/SwiftUI apps for agencies and product teams.

I’ve shipped apps across consumer, enterprise, and B2B verticals: from early MVPs to mature products used by thousands. That depth means I understand not just how to write Swift, but how to architect apps that pass App Store review smoothly and remain maintainable as your project evolves. How I work with agencies and teams: • I adapt to your process: Agile sprints, standups, async updates • Structured daily/weekly progress reporting • Clean, well-documented code ready for PR review • Available during EU + US East Coast hours (CET) • Git workflows, CI/CD, and team codebases Core technical scope: • Native iOS: Swift, SwiftUI, UIKit, Combine • Architecture: MVVM, Clean Architecture, modular patterns • Apple platforms: iOS, macOS, watchOS, tvOS • Backend: Firebase, AWS, REST APIs • Full lifecycle: concept → development → App Store submission I also have cross-platform experience with React Native for projects requiring iOS + Android from a single codebase. With $300K+ earned and a decade on Upwork, I understand what consistent remote delivery takes. If your team needs a senior iOS developer who can take ownership and ship, let’s talk about your project.
