Need a FlutterFlow mobile app that works like a real product, not just a few screens connected together? I help founders, startups, small businesses, and product owners turn app ideas into working iOS and Android MVPs using FlutterFlow, Firebase, Firestore, Supabase, Stripe, APIs, and clean mobile UX. My focus is on building mobile apps with real user flows, backend logic, and the core features needed to test, launch, and improve a product. Whether you are building a fintech app, marketplace, subscription app, community app, booking app, delivery app, AI-powered mobile app, or internal business tool, I can help you structure and build the MVP properly. I can help with: FlutterFlow mobile app development iOS and Android MVP development Firebase and Firestore backend setup Supabase backend setup User signup and login User authentication User profile creation Dashboards and tracking screens Stripe and payment gateway integration Subscription and in-app purchase flows API integration Push notifications In-app search Chat and messaging features Map integration and location-based services Admin dashboards Mobile app bug fixing Mobile app testing Firebase cleanup and app flow improvement UI/UX prototyping for mobile apps If your app needs users to create accounts, make payments, join groups, search content, message other users, track activity, view dashboards, receive notifications, or interact with backend data, I can help you build the right structure. Many app projects fail because the first version is either too basic, too messy, or too disconnected from the business goal. The screens may look good, but the authentication breaks, the database is poorly structured, payment flow is unclear, dashboards do not update correctly, or the app becomes difficult to improve later. That is the problem I help solve. My process is practical. I first clarify the app goal and user flow, then map the screens, define the backend structure, build the frontend in FlutterFlow, connect Firebase or Supabase, set up authentication, integrate APIs or payments where needed, test the core actions, and clean up the flow before handoff. I work best on apps that need real business logic, such as: Fintech MVPs Savings circle or ROSCA apps Marketplace apps Subscription apps Community apps Booking apps Delivery apps Learning apps AI chatbot apps Customer portal apps Mobile dashboards Internal business apps Location-based apps For example, if you are building a savings circle app, I can help structure user signup, verification, create/join group flows, weekly payment tracking, dashboard views, security deposit logic, member status, payment records, and Stripe or payment gateway integration. If you are building a marketplace app, I can help with user profiles, listings, search, filters, chat, map/location features, saved items, admin control, and backend data structure. If you are building a subscription or membership app, I can help with authentication, subscription access, user dashboards, payment flows, push notifications, and account management. If you already have a FlutterFlow app, I can also help fix broken Firebase connections, authentication issues, Firestore query problems, payment errors, navigation bugs, slow user flows, API issues, dashboard data problems, and mobile responsiveness issues. Tools I work with include FlutterFlow, Flutter, Dart, Firebase, Firebase Cloud Firestore, Firebase Realtime Database, Supabase, Stripe, REST APIs, OpenAI API, push notifications, Google Maps API, and mobile app testing workflows. You can expect clear communication, structured app planning, clean FlutterFlow builds, reliable backend setup, careful handling of user data, payment/API integrations that match the user flow, testing before handoff, and practical feedback on what should or should not be in the MVP. I am a good fit if you need a developer who can help with both the build and the structure behind the build. I am not here to just connect random screens. I focus on building mobile apps that users can actually sign into, use, pay through, interact with, and test in the real world. Send me a message with your app idea, feature list, wireframe, or current app link, and I will help you map the best way to build it.

Check my portfolio at stargazerstudio.net/portfolio I mainly work with UK/US brands, often picking up projects where a previous developer stalled or disappeared mid-build — including complex headless setups where standard Shopify assumptions don't apply. In today's global economy, my goal is to give you senior-level, agency-quality work at a fraction of agency overhead. Over 10 years of experience working with brands and agencies. Shoot me a message and I'll give you a quote! My work blends engineering, CRO principles, and product thinking — focused on reliability, performance, and revenue impact.

Your Shopify store should be converting. If it isn't design, speed, product pages, checkout flow, or post-purchase experience — that's the gap I close. I'm a Shopify Expert and ecommerce CRO specialist with hands-on experience building high-converting Shopify stores from scratch, customizing Shopify themes, and optimizing the full customer journey from product discovery to checkout. I also run my own Shopify brand, so I understand the business side, not just the technical side. WHAT I BUILD AND FIX FOR YOU → Shopify store setup — Full end-to-end store build: theme selection, product listings, collections, navigation, payment gateway, shipping rules, and policy pages — live and ready to take orders → Shopify theme customization — Custom modifications to Dawn, Debut, OS 2.0, and Shopify 2.0 themes using Liquid, HTML, CSS, and JavaScript — without breaking speed or mobile responsiveness → Figma to Shopify — Converting Figma designs into pixel-accurate, fully responsive Shopify pages and sections with clean, maintainable code → Conversion rate optimization (CRO) — Identifying exactly where buyers drop off and implementing layout, messaging, and UX improvements that increase add-to-cart rates and average order value → Product page optimization — Rebuilding product pages with trust signals, visual hierarchy, benefit-led copy, upsell and cross-sell sections, and mobile-first layouts that reduce friction at the decision point → Speed optimization — Improving Core Web Vitals, image compression, and lazy loading so your store loads fast on every device and doesn't bleed customers before they even see a product → Shopify app integration — Installing and configuring reviews, loyalty programmes, subscriptions, post-purchase upsells, and shipping tools so every part of your store works together → Dropshipping store builds — Setting up supplier connections via Shopify Collective, Syncee, or product feeds, with automated order routing and stock sync to prevent overselling → Store migration — Moving your store from WooCommerce, Wix, or Squarespace to Shopify cleanly, without losing data, design integrity, or SEO equity → Klaviyo email marketing — Welcome flows, abandoned cart sequences, post-purchase campaigns, and list segmentation that recover revenue on autopilot TECHNICAL SKILLS Shopify / Shopify Plus · Shopify 2.0 · Liquid · HTML · CSS · JavaScript · Figma · Shopify CLI · API integration · Ecommerce Website Development · SEO · Klaviyo · Landing page design · Ecommerce CRO HOW I WORK Every project starts with understanding your customers — who they are, what stops them from buying, and where the current store is losing them. I don't apply templates. I apply thinking. I deliver clean, bug-free code. I communicate proactively, flag issues before they become problems, and I don't disappear mid-project. When I mark something complete, it's client-ready. Most clients return because stores I build stay fast, stay on-brand, and keep converting months after handover. WHO I WORK BEST WITH — Ecommerce founders building their first Shopify store and wanting it done right from day one — Store owners with traffic but low conversion rates who need someone to diagnose and fix the drop-off — Brands migrating to Shopify and needing a clean, professional transition with zero data loss — Businesses that want Klaviyo set up alongside the store, not bolted on later — Clients who value a single point of contact across design, development, and optimization READY TO BUILD A STORE THAT ACTUALLY SELLS?
