I specialize in React and React Native apps - mobile, web, and the backend that connects them. From cross-platform mobile apps deployed to both stores, to complex admin panels with analytics dashboards, personalization engines, and real-time data flows. 🤖 𝐇𝐨𝐰 𝐈 𝐮𝐬𝐞 𝐀𝐈 𝐢𝐧 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐬: I've shipped AI features that solve real business problems, not demos. Recent examples: • Automated clinical documentation for physicians using ambient listening. Doctors capture encounters hands-free, AI generates SOAP notes instantly. Reduced documentation time by hours per day. • AI-powered financial analytics for investors. Real-time market insights, anomaly detection, and AI summaries that surface what matters without manual research. • Integrated AI assistants into SaaS task management. Helping teams manage projects, generate suggestions, and stay on top of workload without switching tools. I also use AI heavily in my own development workflow. Claude Code, Cursor, and AI-assisted testing help me ship MVPs 30-40% faster without cutting corners on code quality. 💡 𝐁𝐮𝐬𝐢𝐧𝐞𝐬𝐬 𝐩𝐫𝐨𝐛𝐥𝐞𝐦𝐬 𝐈'𝐯𝐞 𝐬𝐨𝐥𝐯𝐞𝐝: • A healthcare company needed to connect remote clinicians to hospital EHR systems securely. I built the mobile app and backend integration using SMART on FHIR, cutting manual data entry out of their workflow entirely. • An e-commerce platform was losing $30K/month to fraudulent transactions. I designed and implemented a fraud prevention system across their microservice architecture that stopped it. • A restaurant marketplace needed to compete with large platforms. I built their mobile app, admin portal, and backend from scratch. • An EdTech company needed a way to share educational video without YouTube's ads and recommendations. I built a multi-tenant SaaS platform with branded video pages, role-based access, and analytics. • A fitness brand needed their video library accessible offline and castable to TV. I built a React Native app with custom video players, offline downloads, and casting support. 🏢 𝐈𝐧𝐝𝐮𝐬𝐭𝐫𝐢𝐞𝐬: HealthTech · FinTech · EdTech · E-commerce · SaaS · Fitness & Wellness · Logistics · Restaurant & Hospitality 🚀 𝐖𝐡𝐚𝐭 𝐦𝐚𝐤𝐞𝐬 𝐰𝐨𝐫𝐤𝐢𝐧𝐠 𝐰𝐢𝐭𝐡 𝐦𝐞 𝐝𝐢𝐟𝐟𝐞𝐫𝐞𝐧𝐭: I cover the full product - mobile app, web frontend, and backend - so you don't lose weeks coordinating between developers who don't share context. I've shipped products across iOS, Android, and web. I work in short cycles, keep communication tight, and treat your launch date as a real constraint, not a suggestion. If you're building a mobile SaaS, an AI-powered product, or need to move fast without sacrificing quality - let's talk.
