Most companies I work with are running on Excel sheets, email threads, and CRMs stretched to do things they weren’t built for. I replace that with real internal systems. Ops portals, dashboards, workflow automation, and then layer AI on top where it actually earns its keep. I’ve done this end to end for a Canadian telecom operator. Activations, port ins, moves, DID inventory, all moved off spreadsheets into a central operations system with role based access, audit logs, escalation flows, and CRM integration. Before that, across a university covering HR ERP, archive, publishing, media. Writing FRDs, designing workflows, delivering systems. On AI, I build automations that take work off people’s desks. LLM pipelines using OpenAI GPT and Claude, RAG, n8n workflows and custom AI agents. Lead gen pipelines that search, scrape, qualify, and draft personalized outreach. Content generation with multi platform publishing. Voice to text using Whisper. GPT powered analysis inside shipped products. When a mobile or web app is the right answer, I ship that too. Senior Flutter engineer on ScreenCoach, running on five platforms from one codebase across Android, iOS, Web, macOS, Windows for an Australian startup. CarbonVoice with complex real time animation for a US startup. Matchark in the UK. Also AI native products like Voice Journal AI using Whisper, GPT, and RevenueCat. Top Rated Plus on Upwork. 100% Job Success. 70K+ earned. 2,100+ hours. What I lead on: • Digital transformation of operations. Replacing manual workflows with internal systems. Admin portals, approvals, dashboards, audit logs, role based access, and integrations with your CRM, ERP, and other tools. • AI automation and AI agents. LLM, RAG, OpenAI, Claude. Lead generation, content, qualification, document processing, internal workflows. If someone is doing the same thing twice, I take it off their desk. • Workflow automation. Approvals, notifications, escalation flows, cross system sync. If the process lives across tools, I connect it. • Mobile apps. Flutter across Android, iOS, Web, macOS, Windows. Firebase, REST APIs, RevenueCat, Stripe, real time sync, push notifications. • Web systems. Node.js, React, TypeScript, PostgreSQL, Firebase. Admin dashboards, internal portals, SaaS MVPs, offline capable systems, real time backends with WebSockets. • Requirements and system design. FRDs, acceptance criteria, workflows, low fidelity wireframes. Useful when the client is not fully clear on what they need yet. If you are running operations on spreadsheets and inboxes, or you have a team doing the same work again and again, we should talk.

I build high-quality mobile apps with over 10 years in the field and 6+ years focused solely on Flutter. I deliver clean architecture, reliable performance, and production-ready code. I’m the creator and maintainer of several widely used Flutter libraries—including auto_route, injectable, smooth_page_indicator, and skeletonizer—so you’re working with someone who understands frameworks at their core, not just at the usage level. I can help you: - Develop new Flutter apps from scratch - Modernize or scale existing codebases - Improve performance, architecture, and maintainability - Integrate APIs, authentication, and backend services Clear communication, predictable delivery, and professional execution—every time.

Passionate Flutter developer with 6 years of experience in turning ideas into meaningful mobile experiences. I believe every app has a story to tell, and I’m here to help yours shine through smooth, intuitive design and flawless functionality. With a focus on both performance and user experience, I craft apps that users love to interact with. Let’s bring your vision to life and create something that not only works but feels right at every touch.

Are you building a mobile app from scratch and need it done right the first time? Or is your existing app built on React Native, Cordova, Ionic, or a legacy native stack and it's costing you time, money, and users? Either way, you're in the right place. I'm Vishal, a Senior Flutter Developer with 9+ years of professional experience, where I've delivered 50+ production-grade mobile apps across industries. Whether you're a founder validating your first MVP, an SME scaling your product, or an enterprise modernizing a legacy system - I build Flutter solutions that are clean, scalable, and built to last. 𝐖𝐡𝐚𝐭 𝐈 𝐒𝐩𝐞𝐜𝐢𝐚𝐥𝐢𝐳𝐞 𝐈𝐧: - App Migration (My Strongest Differentiator) Migrating from an old or unstable stack is one of the most high-risk, high-reward moves a product team can make. I've done it multiple times — successfully: ✔ Cordova → Flutter: Women's Club (business networking app) — crash rate dropped from 8% to under 1%, full feature parity preserved ✔ Flutter GetX → Flutter Bloc: Z Ride (ride-hailing platform, Nigeria) — 45% crash reduction, improved booking reliability, full backend and payment overhaul ✔ Legacy Android (Kotlin/Java) → Flutter: complete cross-platform rewrites with zero data loss I understand the complexity of migrations - legacy code, undocumented APIs, fragile state management, and client anxieties. I de-risk every migration with a structured audit, phased plan, and parallel testing before any cutover. 🚀 Building From Scratch → Startups to Enterprises From idea to App Store / Play Store, I've built complete products end-to-end: ✔ Startups & MVPs: Fast, lean, production-ready. I help founders move from wireframe to live app in weeks, not months. ✔ SMEs: Feature-rich, backend-integrated apps with CMS panels, admin dashboards, role-based access, analytics, and payment systems. ✔ Enterprises: Scalable Flutter apps with complex state management (BLoC, Riverpod), CI/CD pipelines, multi-environment builds, Firebase/Supabase backends, and team collaboration support. Real examples: ✔ Flowkar — Social commerce and creator rewards platform. Built from scratch. Scaled to 100,000+ downloads and 32,000 daily active users across 3 countries. ✔ Evbooth — EV charging platform with real-time charging control, Google Maps, and UPI payment integration. ✔ IPBEE — Healthcare mobile app (rated 5.0 ⭐ by client). 🤖 AI Integration into Flutter Apps AI is no longer a nice-to-have → clients expect it. I integrate AI features directly into Flutter apps cleanly and practically: ✔ OpenAI / GPT-4 chat and assistant features ✔ AI-powered recommendations, smart search, and personalization ✔ On-device ML and computer vision integrations ✔ AI chatbot flows with context-aware conversation management I don't just "add an API call" - I architect the AI layer properly so it's maintainable, cost-efficient, and scalable as your user base grows. 📦 Open Source Contributions on pub.dev I don't just build apps, I contribute back to the Flutter community. I've published production-grade packages on pub.dev under Flexion Infotech. 🌐 Flutter Web & Desktop Flutter isn't just mobile anymore. I build full Flutter Web and Flutter Desktop applications for dashboards, internal tools, admin panels, SaaS interfaces with the same codebase as your mobile app where applicable. This reduces development cost significantly for multi-platform products. 💼 Full-Stack Capability I don't just build the app, I handle the entire product delivery: ✔ UI/UX implementation from Figma, Adobe XD, or Zeplin designs ✔ Firebase (Auth, Firestore, Storage, Cloud Messaging, Crashlytics, Remote Config) ✔ Supabase backend integration ✔ REST API and GraphQL integration ✔ Custom backend development (Node.js, Django, when required) ✔ Payment gateways: Stripe, Razorpay, PayPal, UPI, in-app purchases ✔ Push notifications: FCM, OneSignal ✔ Maps & geolocation: Google Maps, MapKit, real-time tracking ✔ Social login: Google, Apple, Facebook, Instagram ✔ Play Store & App Store publishing, ASO, and update management ✔ CI/CD: GitHub Actions, Bitrise, Fastlane 🛠 Technical Stack State Management: BLoC, Riverpod, Provider, GetX, MobX Architecture: MVVM, MVC, MVP, Clean Architecture, SOLID principles Databases: Firestore, Supabase, SQLite (Sqflite), Isar, SharedPreferences Languages: Dart, Kotlin, Java, Swift (for native integrations) DevOps: Git, GitHub, GitLab, Bitbucket, CI/CD Tools: FlutterFlow, VS Code, Android Studio, Xcode 🏆 Why Clients Choose Me ✔ 100% Job Success Score on Upwork ✔ Top Rated badge & consistent 5-star delivery ✔ Published open-source Flutter packages on pub.dev ✔ 50+ apps delivered across healthcare, fintech, logistics, e-commerce, social platforms, etc. 💬 Let's Talk If you're building something new or rescuing something broken, let's have a quick 30-minute call.
