Senior independent iOS / Apple-platform engineer with 10+ years shipping for product teams across operations platforms, healthcare, fintech, media, and B2B SaaS. I partner with founders of B2B operations platforms — equestrian, fitness, healthcare, last-mile logistics, automotive — on multi-month engagements. Not single-feature gigs. Currently in 2-year partnership with a B2B operations platform in the equestrian industry: shipped v1 → seed round closed, architected v2 multi-app ecosystem (barn operations, pro tools, end-user app, payments, orders, billing) → next round in progress. ═══════════════════════════════════════════ FOCUS INDUSTRIES ═══════════════════════════════════════════ ▸ Equestrian operations ▸ Fitness facility operations ▸ Healthcare operations ▸ Last-mile logistics ▸ Automotive services Adjacent operations-tech (case-by-case): agtech, field service, construction tech, hospitality ops, mobile professionals. The common thread: software where digital meets physical, and mobile is mission-critical for operators in the field — drivers, technicians, trainers, practitioners, field workers. ═══════════════════════════════════════════ WHAT I DO ═══════════════════════════════════════════ → Lead end-to-end iOS / Apple-platform delivery for B2B operations platforms (typically post-Series A, $1-15M raised) → Architect multi-app ecosystems (operator + admin + end-user apps) that survive 3+ years of iteration — not just MVP-grade → Embed as fractional CTO when founders need senior Apple judgement without hiring full-time → Audit existing iOS codebases before fundraising rounds or major hires ═══════════════════════════════════════════ WHAT I DON'T DO ═══════════════════════════════════════════ → Single-feature gigs under $3k or 2-week sprints → MVP-from-scratch for non-funded ideas → Cross-platform (React Native, Flutter) — I work native iOS → White-label "rent my GitHub stats" arrangements ═══════════════════════════════════════════ ENGAGEMENT MODES ═══════════════════════════════════════════ ▸ PROJECT PARTNERSHIP (3-9 months) Lead engineer for full delivery cycle. When scope demands more hands, I assemble small senior teams from a network of senior contractors I've worked with for years. ▸ FRACTIONAL CTO RETAINER (6-18 months) 1-3 days/week embedded with founder. Architecture, hiring, code reviews, technical strategy, investor-readiness on the technical side. ▸ ADVISORY DIAGNOSTIC (1-2 weeks) Codebase audit, architecture review, build-vs-buy assessment. Often the start of something longer. ═══════════════════════════════════════════ TECHNICAL STACK ═══════════════════════════════════════════ Apple platforms: iOS, iPadOS, macOS, watchOS, tvOS, CarPlay, Vision Pro Languages: Swift, Objective-C UI: SwiftUI, UIKit Concurrency: async/await, Combine, GCD Architecture: MVVM, Clean Architecture, Coordinators Backend: Supabase, REST/GraphQL APIs Operations-tech: Offline-first sync, GPS/routing, payments, scheduling, multi-app ecosystems Tooling: Xcode, Git, CI/CD (GitHub Actions, Xcode Could, Fastlane, Bitrise), TestFlight, App Store Connect ═══════════════════════════════════════════ Available for 3+ month engagements.

I’m comfortable working with both startups and established teams, and can quickly step into existing projects to provide clear direction and deliver results.

🔥 I am a Senior iOS Developer with industry experience since 2009. I have worked on dozens of mobile applications and continue to strive for quality in everything I create. I help companies create quality products in the beginning, or turn their already created application into one, that will last the test of time so it doesn’t need to be completely rewritten in a few months.
