Ahmedabad, India - 3:03 am local time
If you're looking for a 𝐌𝐨𝐛𝐢𝐥𝐞 𝐀𝐩𝐩 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫, 𝐢𝐎𝐒 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫, 𝐀𝐧𝐝𝐫𝐨𝐢𝐝 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫, 𝐑𝐞𝐚𝐜𝐭 𝐍𝐚𝐭𝐢𝐯𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫, 𝐅𝐥𝐮𝐭𝐭𝐞𝐫 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫, or 𝐀𝐈 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧 𝐄𝐱𝐩𝐞𝐫𝐭, you're in the right place.
My focus is simple: build mobile apps that are fast, maintainable, and ready for scale - whether that's a native iOS app, a cross-platform React Native product, or an AI-powered Flutter application.
Over the last decade, I have worked with startups, product agencies, and enterprise teams across eCommerce, Healthcare, SaaS, Education, and Enterprise - taking projects from early idea all the way to App Store and Play Store.
--------------------------
𝐂𝐨𝐫𝐞 𝐄𝐱𝐩𝐞𝐫𝐭𝐢𝐬𝐞
𝐍𝐚𝐭𝐢𝐯𝐞 𝐌𝐨𝐛𝐢𝐥𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭: Swift & Objective-C for iOS · Kotlin & Java for Android · Full lifecycle from architecture to deployment
𝐂𝐫𝐨𝐬𝐬-𝐏𝐥𝐚𝐭𝐟𝐨𝐫𝐦 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭: React Native & Flutter for high-performance apps that work across both platforms without compromise
𝐀𝐈-𝐏𝐨𝐰𝐞𝐫𝐞𝐝 𝐌𝐨𝐛𝐢𝐥𝐞 𝐀𝐩𝐩𝐬: This is where modern development is heading and I am already building here:
➜ OpenAI / GPT integration for smart in-app features
➜ Claude AI for content generation, logic handling, and code assistance
➜ Cursor IDE for AI-assisted development and clean, scalable architecture
➜ Chatbot development, AI automation, and intelligent app features
➜ Rapid MVP delivery using a Vibe Coding approach
--------------------------
𝐅𝐮𝐥𝐥-𝐒𝐭𝐚𝐜𝐤 𝐌𝐨𝐛𝐢𝐥𝐞 𝐒𝐞𝐫𝐯𝐢𝐜𝐞𝐬
✦ Firebase
✦ REST API
✦ GraphQL
✦ Push Notifications
✦ Payment Gateways
✦ App Store / Play Store Submission
✦ Performance Optimization
✦ Ongoing Maintenance
--------------------------
𝐇𝐨𝐰 𝐈 𝐖𝐨𝐫𝐤
Idea → Planning → UI/UX → Development → Testing → Deployment → Ongoing Support
Every project gets clear communication, honest timelines, and a developer who takes full ownership - not just of the code, but of the outcome.
--------------------------
𝐓𝐨𝐨𝐥𝐬 & 𝐓𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐢𝐞𝐬:
➜ 𝐌𝐨𝐛𝐢𝐥𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭: Swift, Objective-C, Kotlin, Java, React Native, Flutter
➜ 𝐀𝐈 & 𝐌𝐨𝐝𝐞𝐫𝐧 𝐓𝐨𝐨𝐥𝐬: OpenAI API, Claude AI, Cursor IDE
➜ 𝐁𝐚𝐜𝐤𝐞𝐧𝐝 & 𝐀𝐏𝐈𝐬: Firebase, REST API, GraphQL
➜ 𝐃𝐞𝐯 & 𝐕𝐞𝐫𝐬𝐢𝐨𝐧 𝐂𝐨𝐧𝐭𝐫𝐨𝐥: Git, Postman
➜ 𝐃𝐞𝐬𝐢𝐠𝐧: Figma, Adobe XD
➜ 𝐏𝐫𝐨𝐣𝐞𝐜𝐭 𝐌𝐚𝐧𝐚𝐠𝐞𝐦𝐞𝐧𝐭: Jira, Trello, ClickUp, Asana, BaseCamp
If you need a senior mobile developer who can own the full process - from planning through to launch - I'd be glad to connect.
