I'm a Senior iOS Engineer with 11+ years of experience building high-quality native iOS applications using Swift, SwiftUI, UIKit, and Objective-C. I've developed and maintained apps with millions of users, including Travello (6M+ downloads), and have published 20+ apps to the App Store. My expertise includes mobile architecture (MVVM/Clean), REST, GraphQL, gRPC, Firebase, Stripe, video streaming, CI/CD, performance optimization, and App Store releases. I can help you build an iOS app from scratch, modernize an existing codebase, add new features, fix bugs, improve performance, integrate APIs, or prepare your app for App Store submission. I pride myself on writing clean, maintainable code, communicating clearly, and delivering reliable, production-ready solutions on time.

Most Product Managers manage a roadmap from the outside. I've spent 15 years on the inside — actually building the iOS and Android products that PMs typically only spec and track. That background changes how I do this job: I don't ask my engineering team if something's feasible, I already know. I don't pad timelines because I'm guessing at complexity — I've built the thing myself, more than once. I made the transition from hands-on mobile development into product management because I kept ending up owning the "why" and "what" as much as the "how" — prioritizing features, negotiating scope with stakeholders, and making the tradeoff calls that actually shape whether a product succeeds. Now I do that work full-time, with the technical fluency most PMs have to hire someone else to provide. WHAT I DO: • Product roadmap development & feature prioritization • MVP scoping and validation for early-stage products • App monetization strategy — ad mediation (AdMob, AppLovin MAX), in-app purchases, subscriptions • Sprint planning, backlog grooming, and agile delivery coordination • Writing technical specs and PRDs that engineers can act on without back-and-forth • Stakeholder communication — translating business goals into engineering priorities and vice versa • AI-assisted development workflows to speed up iteration and reduce engineering overhead WHAT I USE: • Jira, Confluence, Linear, Notion, Slack, Teams • Figma (for reviewing and iterating on UI/UX with design) • Firebase Analytics, Mixpanel, Amplitude • Claude Code and AI-assisted engineering workflows HOW I WORK: I operate well in fast-moving, high-ambiguity environments — the kind where priorities shift weekly and "we'll figure it out as we go" is the actual plan. I default to clear, frequent communication over big-batch updates, and I'd rather flag a risk early than surprise you with it later. WHY THIS BACKGROUND MATTERS FOR YOU: If you're a startup building your first app, I can help you scope an MVP that's actually buildable in your timeline and budget. If you're an established team looking to grow revenue, I understand the monetization mechanics well enough to make real optimization calls, not just recommend "run more A/B tests." Let's talk about what you're building.

I have 9+ years of Swift and 12+ years of Objective-C experience. I've worked as an engineering lead for the past 8 years as both a contractor and full time employee. In 2018 I published my first book on Swift Playgrounds titled "Simulations in Swift", which has was picked up by Apress. I write articles for the popular Ray Wenderlich/Kodeco website on Server Side Swift, run a YouTube channel teaching Swift development and mentor at a local university. I am the author of several popular Swift libraries including FaceAware and SimpleCheckbox. I write clean, and well tested code for highly polished projects, but also know when to hack things together for quick prototypes and proof of concepts. I've built apps for iOS, Mac, Apple TV, Apple Watch, and I even have significant Server Side (Vapor) experience as well as programming and integrating with embedded systems. If you're looking for a high quality product, with a slick user interface, smooth animations, and is easy for future devs to maintain, choose me!
