Are you stuck with an unfinished FlutterFlow app or need a pro to build one from scratch? I’m a FlutterFlow expert in mobile apps, Firebase, and API integrations — delivering polished apps ready for the App Store & Google Play. 📂 Types of Apps I Build ♦️ Chat & AI-powered platforms (ChatGPT-style, productivity assistants). ♦️ Directories & marketplaces (sports, networking, claimable profiles). ♦️ SaaS & business platforms (CRM, HR apps, admin dashboards). ♦️ Consumer apps (payments, subscriptions, notifications). ♦️ E-commerce & integrations (Stripe, revenue tracking, analytics). 🔑 What I Offer ✔ FlutterFlow Expertise - Build apps from scratch (mobile-first, web-responsive, admin portals). - Convert Figma designs into fully functional FlutterFlow apps. - Extend FlutterFlow with custom actions and widgets in Flutter/Dart. ✔ Integrations & Backend - Firebase: Auth, Firestore, Functions, Storage, Analytics. - Supabase, Xano, Bubble, and REST APIs. - Stripe, RevenueCat, and in-app purchases. - Third-party APIs (Google Calendar, Gmail, CRM, Maps, Mapbox, ActiveCampaign, OneSignal). ✔ Authentication & Security - Firebase Phone Authentication + reCAPTCHA setup. - OAuth, multi-role user permissions, and secure Firestore rules. - SHA1/SHA256 certificate configurations for mobile environments. ✔ Push Notifications & Analytics - OneSignal, Firebase Cloud Messaging, APNs. - Google Analytics, Facebook SDK, custom event tracking. ✔ AI-Powered Features - GPT-4, Gemini, and other AI API integrations. - AI-driven virtual try-on apps (image + garment recognition). - Smart assistants for productivity, chat, and task automation. ✔ UI/UX & Deployment - Pixel-perfect Figma → FlutterFlow builds. - Smooth animations, clean layouts, accessibility support. - TestFlight, App Store & Play Store submission. - CI/CD setup for automated builds and testing. ✔ Maintenance & Performance - Troubleshoot bugs and optimize performance. - Offline handling, scalability, and clean architecture. - Long-term support and feature expansion. 📈 Why I’m Different on Upwork --- Most developers say “I can build your app.” I go further: ♦️ I speak the client’s language. I know you care about deadlines, clean UI, and working integrations, not just “lines of code.” ♦️ I prioritize fast delivery. I use FlutterFlow to get you results quickly without sacrificing quality. ♦️ I help you launch. From prototype → MVP → full release, I guide you through the launch process. ♦️ I build long-term relationships. Many of my clients return for ongoing enhancements, maintenance, and scaling. 📂 Portfolio (What You’ll See in My Profile) ♦️ Social Networking App → FlutterFlow + Firebase Auth + Push Notifications. ♦️ E-commerce App → Stripe Integration + In-App Subscriptions. ♦️ Meditation App → Flutterflow + Firebase Auth + Cloud Functions ♦️ Fight Booking App → Figma + Flutterflow + Firebase Auth + Revenue Cat + Stripe ♦️ AI Chatbot App → OpenAI GPT-4 integration in FlutterFlow. ♦️ Business CRM Dashboard → FlutterFlow + Supabase + API Integrations. Each project is displayed with screenshots + results so you can see my work clearly. ⭐ Client Promise When you work with me, you can expect: ♦️ Clear communication - I am very active and ready to communicate via texts and calls (daily or weekly updates, your choice). ♦️ On-time delivery (I scope properly and avoid over-promising). ♦️ Problem-solving mindset (not just a developer, but a partner). ♦️ 5★ quality (my goal is always to make you a repeat client). 👉 Click “Invite” or “Hire” to start a chat about your project. Let’s turn your idea into a launch-ready FlutterFlow app. PS "I don’t just build apps—I help you build your business. With a focus on speed, scalability, and user experience, I create apps that solve problems today and grow with you tomorrow."

⭐⭐⭐⭐⭐As a Notion Consultant, I specialize in building powerful, easy-to-use systems that streamline your workflows, automate repetitive tasks, and give you full visibility over your operations. Whether you're overwhelmed with scattered information or struggling to scale your processes, I design tailored Notion workspaces that actually work for you. If your Notion workspace feels confusing, unorganized, or takes too much time to manage, it can slow down your work and make simple tasks feel harder than they should be. A clear and well structured system helps you stay focused, saves time, and makes your daily work easier to handle. You get a setup where your tasks, projects, notes, and client work are all in one place and easy to find. No more jumping between pages or trying to remember where things are stored. Everything is arranged in a simple way that fits how you already think and work. Your dashboards can show what matters most to you. This can include your daily tasks, project progress, deadlines, or client updates. With everything in one clear view, it becomes easier to plan your day and keep track of your work without stress. Automation also helps reduce repeated tasks. With tools like n8n, some actions can happen automatically in the background. This means less manual work and more time to focus on important tasks that need your attention. The focus is always on making your system simple, clear, and easy to use. A good Notion setup should support your work, not slow you down. When everything is organized the right way, you can work faster, stay focused, and feel more in control of your workflow every day. 💥I design Notion systems for: ✔Clear project management ✔Organized administrative support ✔Team communication and visibility ✔Structured documentation hubs ✔Scalable operations systems For advanced needs, I integrate Artificial Intelligence into Notion workflows. I work with OpenAI, GPT, and Claude to help generate content, summarize data, manage information, and support better planning. These Notion systems are simple to use and easy to maintain, identify weak points, and design a Notion system that supports growth, clarity, and better decisions. If you want a clean, reliable, and scalable Notion system for your team or business, I can help. My approach is simple: understand your workflow, eliminate inefficiencies, and build a system that saves you time every single day. I don’t just build dashboards, I build systems that think.
