I'm Neelam, a mobile and web app developer specializing in AI-powered applications, native iOS and Android, and cross-platform apps in React Native and Flutter. I hold a 100% Job Success Score and Top Rated status on Upwork, backed by 10+ years building products — much of it outside this platform. I don't just write code. I think through your product, challenge weak assumptions early, and build things that hold up in the real world. My edge? I've shipped across enough domains — health, fintech, social, ecommerce, sports, media, edtech — to know what works before the first line of code. My sharpest focus right now is AI-powered mobile and web apps: products that don't just look smart, but genuinely behave that way. WHAT I BUILD ➜ AI & Intelligent Apps — LLM integrations, automation pipelines, OpenAI, custom AI workflows ➜ Native Android — Kotlin | Java | Android Studio ➜ Cross-Platform — React Native | Flutter | FlutterFlow ➜ Web — React.js | Next.js | HTML/CSS ➜ Backend & APIs — Python (FastAPI, REST) | Node.js | Express.js ➜ Database & Cloud — PostgreSQL | MongoDB | Firebase | AWS | Google Cloud | Azure ➜ AI-Assisted Development — Claude Code, Cursor, Windsurf, GitHub Copilot, Replit, Lovable WHAT WORKING WITH ME LOOKS LIKE No ghosting. No vague updates. No surprises at the finish line. I follow Agile Scrum, communicate proactively, and treat your deadline like it's mine — because my reputation depends on it. Need more firepower? When a project calls for it, I can scale up with a dedicated senior team — same standards, more bandwidth, with my oversight at every stage. If you're serious about building something that works, hit "Invite Now" and let's talk.

🎯 Top Rated | 100% Job Success | Trusted by global clients React Native & MERN Stack Developer | 10+ Years | 77+ Projects Delivered I have spent the last 10+ years building full-stack web and mobile applications that don’t just work, but scale smoothly as products grow. With 77+ completed projects and a consistent 100% Job Success Score, I focus on delivering systems that are reliable, maintainable, and ready for real users. My core strength sits at the intersection of React Native and the MERN stack, helping founders and teams build connected web and mobile experiences without fragmentation. What I Do: I build complete products end-to-end, from frontend to backend to deployment. ▸ Mobile Apps: React Native apps for iOS and Android with clean architecture and smooth performance ▸ Frontend (Web): React.js, Next.js, responsive UI, dashboards, SaaS platforms ▸ Backend: Node.js, Express.js, REST APIs, authentication, scalable architecture ▸ Database: MongoDB (design, optimization, schema structuring) ▸ Integrations: Third-party APIs, payment systems, real-time features ▸ Deployment: AWS, Vercel, CI/CD pipelines, production-ready setups How I Work ▸ Plan architecture that supports scale from day one ▸ Keep code clean, structured, and easy to extend ▸ Maintain clear communication with regular updates ▸ Work closely with product teams to align tech with business goals ▸ Deliver features that are stable, tested, and production-ready Clients usually come to me when: ▸ They need one developer who can handle both mobile apps and web applications without handoffs ▸ They’re building a product and want a strong foundation for both web and mobile from the start ▸ They need a React Native mobile app connected seamlessly with a web application backend ▸ Their existing mobile or web app needs fixing, scaling, or proper completion ▸ They want clean, maintainable code that’s built for long-term use, not quick patches Experience Snapshot ▸ Web applications with dashboards, user flows, and subscription systems ▸ Mobile apps with real-time features, notifications, and live data ▸ Marketplace and booking platforms across web and mobile ▸ Mobile apps fully connected with scalable backend systems ▸ API-driven products with multiple third-party integrations Approach I start by understanding the product, not just the features. Once the direction is clear, I build with proper structure and clarity, avoiding shortcuts that cause issues later. The focus is always on creating web and mobile applications that run smoothly now and are easy to scale over time. Let’s Talk If you're working on a mobile app, web application, or both, I can help you plan, build, or complete it the right way. Send me a quick message with your idea or current setup, and I’ll take it from there.

Most founders reach me at the same moment: the app was built fast, and now it's showing the cracks. Features that passed testing behave differently in production. Performance drops on Android and iOS. A launch deadline has quietly turned into a long maintenance problem. I step in, understand the product, the users, and the real state of the code, then set the right direction, whether that's a fresh React Native build or an existing codebase that needs a steadier hand.

The only thing users noticed was that the app finally felt fast. → Another app had Supabase RLS rules open enough that any logged-in user could read any row in the database. I caught and fixed it before launch, well before it could become a breach. That's the real work: not just shipping features, but reading what's already there, finding what's quietly broken, and fixing it before it costs real money.

Most developers build what you ask for. I help you build what your business actually needs. Whether you're launching a SaaS platform, developing a custom web application, or building a mobile app, I focus on creating software that's scalable, maintainable, and aligned with your business goals. Over the past 8+ years, I've delivered 50+ web and mobile applications across healthcare, marketplaces, logistics, fintech, business automation, and enterprise software. Most of my work falls into four buckets: marketplace/on-demand platforms, social and dating apps with real-time features, custom software built around a specific business process, and backend integrations (Twilio, Stripe) that other developers get stuck on. Technologies I work with: Flutter • React Native • React.js • Next.js • PHP (Laravel) • Python • Node.js • Firebase • AWS • MongoDB • PostgreSQL • Stripe • Twilio • OpenAI APIs 𝐖𝐡𝐲 𝐜𝐥𝐢𝐞𝐧𝐭𝐬 𝐫𝐞𝐡𝐢𝐫𝐞 𝐦𝐞: I scope before I code , you'll know what you're getting and roughly when, before I start. When something in the spec doesn't add up, I flag it early instead of building around it silently. And I hand off documented code, not a black box, so you're not stuck coming back to me for every small change. If you're building custom software, a marketplace, a healthcare or on-demand app, or need someone who can actually finish a Twilio or Stripe integration without three follow-up calls" 𝐥𝐞𝐭'𝐬 𝐭𝐚𝐥𝐤 𝐚𝐛𝐨𝐮𝐭 𝐰𝐡𝐚𝐭 𝐲𝐨𝐮'𝐫𝐞 𝐛𝐮𝐢𝐥𝐝𝐢𝐧𝐠."
