👋 Hey, thanks for stopping by my profile. 🚀 Flutter Developer | AI-Powered Builds | Top Rated Plus on Upwork I've spent the last 8 years turning app ideas into things people actually use. Most of that has been deep in Flutter, building cross-platform apps that feel native on both iOS and Android — but I've also worked with native Java/Kotlin, full-stack web, and a handful of other languages along the way (JavaScript, PHP, HTML/CSS, Dart, Vue Js, React and AWS). Lately, I've been a bit obsessed with how AI changes the way I work. I use AI-assisted tools to prototype faster, catch bugs earlier, and iterate quicker — which means you get the same quality, just sooner and often for less. And when a project calls for speed over a full custom build, I'll reach for no-code and low-code tools to get an MVP in your hands fast, so you can test the idea before sinking a budget into it. 🌟 Why Choose Me? ✔ Expert in Flutter: I craft cross-platform apps with native-like feel and performance — one codebase for iOS and Android means lower cost and faster time-to-market. ✔ AI-Powered Productivity: I integrate AI tools into my development process to accelerate delivery without cutting corners — faster prototyping, smarter debugging, automated testing, and quicker iterations. You get the same quality, delivered sooner. I also build AI features into apps: chatbots, smart search, content generation, and API integrations with leading AI models. ✔ No-Code & Low-Code Solutions: When speed and budget matter most, I leverage no-code and low-code platforms to stand up MVPs, internal tools, and rapid prototypes — so you can validate your idea quickly before investing in full custom development. ✔ Custom App Development: Whether you need a sleek UI, complex functionality, or third-party integrations, I tailor your app to your exact specifications. ✔ Strong Problem Solver: I thrive on challenges. No matter the complexity, I'm committed to finding the best solution to meet your goals. ✔ Responsive Communication: Clear, transparent communication drives successful projects. I'm available to discuss progress, answer questions, and address concerns promptly. Here's what I'm good at: 🌟 Flutter & mobile Development: ✔ clean, responsive UI ✔ Firebase ✔ push notifications ✔ Google/Facebook/Apple sign-in ✔ Maps ✔ ads ✔ API integration ✔ Basically, everything it takes to ship a polished app. 🌟 AI features & automation user of AI tools ✔ adding chatbots, smart search, and content generation into apps, plus integrating the major AI models via API. I also automate the boring parts of a workflow so the app (and the team behind it) runs leaner. ✔ Claude code, Cursor, and many more 🌟 No-code / low-code ✔ Fast MVPs, internal tools, and quick prototypes when validating an idea matters more than a from-scratch build. 🌟 Full-stack ✔ REST and GraphQL APIs, auth, SQL and NoSQL databases, deployment, and third-party integrations. Comfortable across AWS too. What it's like working with me: I'm a straightforward communicator — I'll keep you in the loop, flag issues early instead of at the deadline, and tell you honestly if I think there's a better way to do something. I genuinely like solving hard problems, so the messy, complicated projects don't scare me off; they're usually the fun ones. If you've got an idea — I'm committed to your project's success. Let's collaborate to create an app that exceeds your expectations. Talk soon, Sheetal S.
