Proof of execution

Products built,
shipped, and used.

Every project here is something I designed, built, owned, and shipped. Not a mockup. Not a side project. Real products with real users and real engineering decisions behind them.

OmniFlyer: Aviation Operations Platform

Founded and built from zero. OmniFlyer is a modern SaaS platform for flight schools and flying clubs. Aircraft scheduling, member management, fleet visibility, and booking conflict prevention. I own every layer: product, architecture, and code.

Live on App Store iOS · SwiftUI · Firebase

Elumi: Couples' Daily Ritual App

Designed and built solo. A daily shared ritual for couples: one question, private answers, simultaneous reveal. SwiftUI + Firebase + RevenueCat, shipped to the App Store end-to-end.

Security-Critical · Live iOS · Encryption · RSA

TruCrypt: Encrypted Messenger

End-to-end encrypted communication for iOS. RSA-3072 encryption, zero-knowledge architecture, built for professional and enterprise environments where security is non-negotiable.

Engineering Inside Products Serving Millions

Experience building software inside organizations that serve millions of users: Duolingo (500M+ users), Lufthansa Systems (safety-critical aviation software), Bosch (IoT consumer hardware), and Elli by Volkswagen (EV infrastructure). What I learned about quality, scale, and product thinking.

The through-line

One engineer. Four distinct engineering challenges.

Every project here is a different type of software problem. Together they tell you what kind of engineer I am: someone who ships complete products, not features inside someone else's product.

SaaS

OmniFlyer

Multi-tenant architecture, role-based access control, real-time scheduling, subscription billing. What it takes to go from zero to a production SaaS as a solo founder.

Consumer iOS

Elumi

SwiftUI, Firebase backend, RevenueCat subscriptions, App Store distribution. What it takes to ship a polished, monetized native iOS product alone from concept to live.

Security-critical

TruCrypt

RSA-3072 encryption, zero-knowledge server architecture, iOS Keychain integration. What it takes when the security model has to be correct before anything else.

Enterprise scale

Duolingo, Lufthansa, Bosch, Elli

500M+ users, safety-critical aviation software, IoT hardware, EV infrastructure. What it takes to write code that has to keep working when the stakes are real.

If you're building a product that needs to be engineered well, not just built quickly, this is the track record.
