I help clients build and improve Apple-platform apps with a strong focus on Swift, SwiftUI, widgets, native integrations, macOS companion apps, notifications, background functionality, and polished product UX. I’m an iOS/macOS Software Engineer with 5+ years of commercial development experience. On Upwork, I’ve completed 12 client engagements with a 100% Job Success score and Top Rated Plus status. Most of my work has been with U.S. clients in English-speaking teams. I can help with: • Swift / SwiftUI development for iOS, macOS, and iPadOS • WidgetKit, notifications, background work, and Apple native integrations • macOS companion apps and desktop-oriented workflows • UI modernization, bug fixing, and performance/stability improvements • REST / GraphQL integrations, offline persistence, subscriptions, and analytics • shipping production-ready features with clean, maintainable architecture I also use modern AI-assisted workflows pragmatically — including Codex, Claude, MCP tools, and Figma Make — to accelerate implementation, debugging, refactoring, research, and documentation where it benefits the project. If you need someone who can quickly understand an existing codebase, improve the product, and deliver strong native Apple-platform work without excessive hand-holding, I’d be glad to discuss your project.

I help founders and small teams ship or repair mobile products fast: SwiftUI/iOS, Firebase, Supabase, and API integrations. If you have a broken feature, a clear MVP, or an existing codebase that needs focused execution, I can get it to a clean, testable handoff. I hold an M.S. in Software Engineering and use a practical, AI-assisted development workflow. I start by clarifying what “done” means, trace the existing behavior, make the smallest reliable change, verify it, and document the handoff. My strongest hands-on work includes: • SwiftUI and UIKit mobile features: navigation, feeds, forms, maps, media, profiles, and device-framework integrations • Firebase: Auth, Firestore, Cloud Functions, public/private data separation, authorization rules, and mobile-app hardening • Supabase: Auth, PostgREST, Storage, RPC, relational queries, and reusable Codable CRUD patterns in Swift • Product MVP work: focused screens, backend wiring, acceptance checks, and lean user flows • API and automation work: TypeScript/Next.js, webhooks, email delivery, serverless workflows, and integration debugging I’m especially useful for well-scoped work such as: • Fixing a reproducible SwiftUI, UIKit, Firebase, Supabase, React Native, or TypeScript issue • Completing one focused screen, flow, or backend integration • Moving a prototype from mock data to a real API or backend path • Investigating an error, defining the smallest fix, and documenting the handoff Relevant work includes a collaborative SwiftUI social-events MVP with feed, MapKit, media, profile, and Supabase functionality; a UIKit AudioKit/MIDI prototype with Firebase persistence; and a UIKit country-browser project with async networking, retry/fallback behavior, and focused tests. Send the goal, affected code or error, and how you will know the task is complete. I’ll respond with the smallest sensible plan, open questions, and a realistic delivery estimate.
