Is your app becoming difficult to maintain or are you not even sure what you should build yet? I help turn unclear product ideas and problematic existing apps into practical, maintainable products - from technical discovery to MVP, launch and beyond. I’m a senior mobile developer and full-stack developer with 8+ years of experience and $900K+ earned on Upwork. I don’t just write code. I help you figure out what to build, how to build it and how to avoid wasting development budget. How I can help 🔹 From idea to product Got an idea, but aren't sure what the actual product should look like? I start with a discovery phase to understand the business goal, users, workflows, requirements and constraints. Then I help define the scope, architecture, MVP roadmap and technology stack. The goal is to validate the idea and build the right MVP, not spend months on features nobody needs. 🔹 Technical discovery & audit Already have an application but aren't sure what needs to be fixed or rebuilt? I review the codebase, architecture, integrations and release process to identify risks, technical debt, priorities and the best path forward. You will get: - Key risks and dependencies - Recommended options with trade-offs - A prioritized roadmap - A phased estimate separating urgent work from improvements 🔹 MVP development & product delivery I take the product from discovery through architecture, UX implementation, development, integrations, testing, release and ongoing improvements. You get one technical partner who can see the whole picture instead of coordinating multiple specialists. 🔹 Technical feasibility & proof of concept If your product depends on difficult assumptions - GPS, background processing, BLE/NFC, AI output, camera workflows, offline sync or third-party APIs - I build a focused proof of concept to test the riskiest assumptions before a large build. 🔹 Modernizing legacy applications Running Xamarin, WPF or another aging technology? I assess the existing codebase and create a phased modernization path - such as Xamarin to .NET MAUI, WPF to MAUI or Flutter, while preserving valuable business logic, APIs and workflows. 🔹 Rescuing existing applications Inherited a problematic codebase? Original developer left? Production bugs keep returning? I diagnose architecture, integrations, platform and release issues, then create a clear path to stabilize and extend the product. 🔹 Cross-platform applications I build maintainable applications across iOS, Android, Windows, macOS and web, using cross-platform technologies where they make sense and native integrations where they don't. This includes offline-first workflows, GPS, BLE, NFC, cameras, background processing, local storage and synchronization. 🔹 Integrations & product workflows I connect APIs, authentication, databases, payments, analytics, cloud services, third-party SDKs and AI services into reliable end-to-end workflows. 🔹 Release & ongoing development I take working code through CI/CD, builds, signing, App Store / Google Play releases, deployment and post-launch improvements. 💻 Working with your team I can work independently or alongside your developers, designer, CTO, product manager or existing agency. I’m comfortable joining an established codebase, working from tickets and documentation, participating in code reviews and owning a defined technical area. ▶️ Typical ways to start - Technical discovery: audit an idea, codebase, architecture, or integration. - Focused rescue: fix a production issue, release blocker, or failing integration. - MVP delivery: define scope, build the foundation, and launch. - Modernization: migrate, refactor, or rebuild a legacy product. - Long-term development: add features and improve reliability. ⚙️ Technologies Mobile: Flutter, Dart, .NET MAUI, Xamarin, native iOS & Android integrations Frontend: React, Blazor, Blazor Hybrid, Flutter Backend: .NET, C#, Node.js, Firebase, PostgreSQL, AWS, REST APIs Integrations: payments, authentication, analytics, third-party APIs, BLE/NFC/GPS, AI/LLM APIs 🤖 AI-assisted development I use AI where it genuinely improves development speed - codebase exploration, documentation, research, prototyping, testing, refactoring and low-risk implementation. This keeps more of your budget focused on architecture, product decisions, complex integrations, testing and quality control. AI is a productivity tool, not a substitute for engineering judgment. I review, test and take responsibility for the code delivered. 🚀 Whether you're starting with "I have an idea", "I need an MVP", "this app needs to be modernized" or "this codebase is becoming impossible to maintain" - I can help you figure out the right next step and take it through to a working product. The first step is choosing the right solution. Send me a message or invite and let’s get started today.

Hi, I'm Ranjit — a HIPAA certified mobile and PWA developer who helps healthcare, wellness, and fitness founders turn their web prototypes into production-ready iOS and Android apps without rebuilding from scratch. If you've built something on Lovable, Base44, or Replit and now need it live on the App Store and Play Store, that's exactly what I do. Using Capacitor, I wrap your existing PWA into native iOS and Android apps — preserving your codebase, cutting your timeline by 60–70%, and giving you full access to native features (push notifications, camera, HealthKit/Google Fit, biometric auth, in-app purchases, background sync). Where I focus: Women's Health & Fertility — IVF/IUI cycle tracking, period & ovulation logging, clinic portals, telehealth flows Gym & Fitness — Coaching apps, workout tracking, multi-location gym management (attendance, billing, trainer portals) Wellness & Nutrition — Mindfulness, habit tracking, meal planning, hydration, sleep Healthcare adjacent — HIPAA-aware data handling, secure auth, EHR/clinic integrations What you get working with me: A working app on TestFlight / Internal Testing within 2–3 weeks (typical PWA-to-mobile conversion) Full App Store and Play Store submission handled end-to-end (certificates, provisioning, store listings, review responses) Native features bolted on cleanly — push notifications (Firebase/OneSignal), offline mode, biometric login, native sharing, deep linking Code that your future team can actually maintain — clear structure, documentation, and a deployment guide My stack: React Native, Capacitor, Ionic, React, Next.js, TypeScript, Firebase, Supabase, REST/GraphQL APIs, Stripe/RevenueCat for subscriptions. I respond within a few hours, work in overlap with US/EU time zones, and I'd rather start with a 20-minute discovery call than send you a generic proposal. If you've got a PWA, prototype, or web app that needs to become a real mobile product — let's talk.
