What We Build
Mobile-first products, not a feature checklist
Consumer-facing and mission-driven builds, aligned with how I ship on my own work. Fast execution, precise UI/UX, scalable architecture, and business alignment from MVP to tens of thousands of users.
Mobile apps for iOS and Android
End-to-end product builds from idea to App Store and Play Store: polished UI, performance, and release readiness. Grounded in a decade of shipping high-impact consumer apps with Swift, SwiftUI, React Native, and modern mobile architecture.

Backends, APIs & integrations
Secure APIs, cloud backends, and third-party integrations so your app is more than a pretty screen. Real data, auth, payments, and scalable foundations behind the scenes, including Next.js APIs and server routes where it fits.
Next.js · Firebase · REST · TestFlight
AI-powered apps
AI features wired through modern APIs from providers like OpenAI, Google Gemini, and Replicate. Chat, image generation, embeddings, and smart workflows inside your app, with product thinking on prompts, cost, and UX.

Social & community products
Social networks, engagement loops, and community tools, built for retention and trust, from profiles and feeds to messaging and moderation-ready patterns.
real-time patterns · engagement · growth
Fintech, marketplaces & subscriptions
Money-moving experiences: group savings, payments, subscriptions, and marketplace flows, with clarity for users and robustness for compliance-minded teams.
payments · subscriptions · dashboards
Utility, discovery & mission-driven apps
Apps that replace spreadsheets and manual processes: discovery, booking, housing access, health-adjacent flows, and internal tools your team actually uses on mobile.
