Mobile Full-Stack Developer | Flutter | React Native | AI Integration

Mobile apps don't fail because of missing features. They fail because of bad architecture, compliance gaps, and developers who disappear after handoff. 𝐎𝐯𝐞𝐫 𝐭𝐡𝐞 𝐩𝐚𝐬𝐭 𝟖 𝐲𝐞𝐚𝐫𝐬, I've built and shipped 𝟏𝟓+ 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧 𝐚𝐩𝐩𝐬 across Flutter, React Native, Swift, and Kotlin, including a payment SDK deployed to 𝟏𝟎𝟎+ 𝐉𝐏𝐌𝐨𝐫𝐠𝐚𝐧 𝐦𝐞𝐫𝐜𝐡𝐚𝐧𝐭𝐬, a healthcare communication app that grew 𝟑𝟎𝟎% in 𝐀𝐩𝐩 𝐒𝐭𝐨𝐫𝐞 𝐫𝐞𝐯𝐞𝐧𝐮𝐞, a Flutter music player app with 𝟏,𝟎𝟎𝟎,𝟎𝟎𝟎+ 𝐝𝐨𝐰𝐧𝐥𝐨𝐚𝐝𝐬, and an AI-powered sports rule app that added $𝟏𝟒𝟎𝐊+ 𝐢𝐧 𝐀𝐑𝐑 through native paywalls. These weren't projects where I wrote code to spec. Each one required owning technical decisions, navigating App Store policy, designing architecture that could scale, and integrating systems that had no simple documentation - Twilio VOIP, BLE firmware OTA, PCI-DSS payment flows, NDIS compliance workflows, RAG pipelines on top of LLMs. 𝐎𝐧 𝐭𝐡𝐞 𝐀𝐈 𝐬𝐢𝐝𝐞, I've built production 𝐑𝐀𝐆 𝐬𝐲𝐬𝐭𝐞𝐦𝐬 𝐮𝐬𝐢𝐧𝐠 𝐋𝐚𝐧𝐠𝐂𝐡𝐚𝐢𝐧 𝐚𝐧𝐝 𝐏𝐢𝐧𝐞𝐜𝐨𝐧𝐞, 𝐢𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐞𝐝 𝐎𝐩𝐞𝐧𝐀𝐈 𝐀𝐏𝐈𝐬 𝐢𝐧𝐭𝐨 𝐦𝐨𝐛𝐢𝐥𝐞 𝐚𝐩𝐩𝐬 for real-time task detection and natural language search, and shipped an LLM-powered rules engine that became a commercial product. This isn't experimentation - it's shipped and monetized. 𝐈𝐧𝐝𝐮𝐬𝐭𝐫𝐢𝐞𝐬 𝐈'𝐯𝐞 𝐬𝐡𝐢𝐩𝐩𝐞𝐝 𝐢𝐧: • Healthcare • FinTech • Sports • Workforce management • IoT • Media • Disability services. 𝐌𝐲 𝐓𝐞𝐜𝐡 𝐬𝐭𝐚𝐜𝐤: Flutter, React Native, Swift, Kotlin, Node.js, TypeScript, Firebase, Firestore, AWS, OpenAI APIs, RAG, LangChain, Pinecone, Twilio, RevenueCat, Superwall, Adapty, BLE, REST, GraphQL, and payment integrations across Stripe, NMI, Square, PayPal, and SEPA. If you're building something that has to work - App Store approval, compliance requirements, payment flows, AI features, or a migration that can't break production, that's where I do my clearest work. 𝐓𝐨𝐩 𝐑𝐚𝐭𝐞𝐝 𝐨𝐧 𝐔𝐩𝐰𝐨𝐫𝐤. 𝟏𝟎𝟎% 𝐉𝐨𝐛 𝐒𝐮𝐜𝐜𝐞𝐬𝐬 𝐒𝐜𝐨𝐫𝐞. Available for a scoping call to see if there's a fit.
