Marcus K.

Engineering Manager at What's The Move — an event-based social media app I helped build and launch. I also built DragSet, a social media app, from the ground up. Choose a clear starting point in my Project Catalog: a $199 one-day bug fix, a custom website from $999, or an iOS app MVP from $999. Website and app starter packages take 7 days after complete requirements are received. 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.
