Mobile app developer with 14+ years of mobile app development, 80+ apps shipped, and a Flutter app past 2M+ users.
⭐ Top Rated on Upwork since 2018 · 5.0 on Clutch · 4.93 on GoodFirms
If you're starting a Flutter app from scratch, I take it from concept to the App Store. If your iOS or Android app has stalled, I get it shipping again. If a previous mobile app developer missed what you actually needed, that's where I usually come in.
𝗪𝗵𝗮𝘁 𝘆𝗼𝘂 𝗴𝗲𝘁
✔️ As a Flutter developer I ship one codebase to iOS and Android at once, up to 40% cheaper than two native builds.
✔️ The mobile app design and the mobile app development come from the same person. No handoffs, no two contractors blaming each other.
✔️ Healthcare apps that pass HIPAA and GDPR. Logistics apps that keep working when the signal drops.
✔️ Hire the wrong mobile app developer and the scope gaps surface at the first build. I flag them earlier, and clients have brought me in to redo exactly that.
✔️ 80+ apps in, I have already hit the problems your build will run into. One app I built passed 2M+ users.
Send me what you're building and I'll reply with a scope estimate and the first technical decision I'd settle. Clients come back a year in after hiring the wrong mobile app developer first; early hires save months.

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.
