Update to current app
Working with this team was a genuine pleasure. Getting an MVP live was no small thing, and they made it happen. They brought real effort, patience, and technical skill to the project from start to finish. I’m closing the contract as my product moves into its next phase that’s entirely on where Checkin is heading, not the quality of their work. I’d have no hesitation recommending them. Any project would be in good hands.

I build mobile apps with the AI running inside them, not bolted on afterwards. Over the last few years I've taken startups from wireframe to a launched product on the App Store and Play Store, and the work that keeps coming back to me is the kind where the AI is the product: an AI coach that adapts to the user, an AI companion people talk to every day, a calorie tracker that reads a photo of a plate, an AI receptionist that answers the call and books the appointment. 100+ projects in, I ship to the store, not to a repo.
Here's what I can help you with:
✔ AI Chat, Companions & Assistants: conversational assistants, AI companion and mental wellness apps, copilots powered by the OpenAI API, ChatGPT, GPT-4, Claude API from Anthropic or Gemini, plus RAG assistants built with LangChain and vector databases that answer from your own documents, and AI content creation tools. I handle streaming responses, prompt and context design, AI agents and cost-optimized API usage, so your token bill doesn't scale faster than your users do.
✔ AI Vision & Scanning: calorie and food recognition from a single photo, body and object scanning with TrueDepth, document and receipt capture, and on-device ML with Core ML and ML Kit where latency or privacy rules out a round trip to the cloud. I've shipped TrueDepth foot scanning to production, so I know where Apple's camera and permission rules actually bite.
✔ AI Voice Agents & Receptionists: appointment-setting and calling agents, in-app voice assistants, speech-to-text and text-to-speech pipelines with Whisper, Deepgram and ElevenLabs, telephony through Twilio, Vapi and Retell, plus WhatsApp and Telegram bots. Most voice agent builders stop at the phone line. I put the agent inside your app.
✔ Health, Fitness & Wellness Apps: my deepest vertical. AI fitness and habit coaching, nutrition and diet tracking, meditation and mental health apps, and telehealth builds wired into HealthKit and Health Connect, including the privacy manifest and health scope justification that gets most health apps rejected on first submission.
✔ AI-Powered MVPs for Startups: wireframe to launched product on iOS and Android, including AI-enhanced marketplaces and booking apps. Built in Flutter and Dart, React Native and Expo, FlutterFlow, or native Swift and Kotlin where it earns its place, with Stripe, RevenueCat and in-app purchases wired in and TestFlight to store release handled end to end. Scoped so you ship something real users can pay for, not a demo that only works in the investor deck.
✔ Adding AI to an App You Already Have: AI chat, smart search, recommendations, document processing and workflow automation dropped into your existing codebase without a rebuild, backend included when it needs one, in Node.js or Python with Firebase, Firestore, Cloud Functions, Supabase, PostgreSQL, REST and GraphQL APIs.
✔ App Store & Play Store Publishing, Bug Fixing & Maintenance: App Store Connect and Google Play Console submission, TestFlight builds, and rejected apps resubmitted and approved. Mobile app bug fixing, crash and performance optimization, Flutter and React Native version upgrades, API and SDK migrations, and long-term maintenance and support so your app keeps working after launch. If you built something with Rork, Lovable, Bolt or Cursor and it won't pass review, I take it over, give you an honest audit, and get it live.
