I have been building reliable mobile apps across iOS and Android for the past 5 years, focusing on production-ready apps that scale from MVP to full products used by real businesses.
I work across Flutter and React Native, and also develop native modules in Swift and Kotlin when platform-specific functionality is required.
What I Build
Cross-platform mobile apps using Flutter and React Native (Expo, TypeScript)
Native iOS apps with SwiftUI and Android apps with Kotlin when needed
AI-powered mobile apps — chatbots, smart recommendations, LLM features
Real-time and video calling apps — WebRTC and live data systems
Maps and location apps — Google Maps, Mapbox, GPS tracking
MVPs — production-ready in weeks and built to scale
SaaS, FinTech, IoT, inventory, on-demand, and business apps
Technical Stack
Mobile: Flutter, React Native (Expo), SwiftUI, TypeScript, Native Modules (Swift, Kotlin)
AI: OpenAI API, LLM integration, AI chatbots, recommendations
Maps: Google Maps SDK, Mapbox, geolocation, GPS tracking
Real-time & Video: WebRTC, real-time communication systems
Backend: Node.js, NestJS, REST APIs
Database: MySQL, MongoDB, Firebase, Supabase, Redis
Payments: RevenueCat, in-app purchases, Stripe
Integrations: BLE, IoT, push notifications, text-to-audio
Deployment: App Store, Google Play, CI/CD, GitHub Actions, EAS Build, Firebase Analytics, AWS
What Sets Me Apart
I focus on building production systems, not just app screens.
My work often involves:
Mobile apps with an offline-first architecture that work without the internet
AI features that add real product value
BLE and IoT hardware integrations with a mobile app.
Real-time communication and video platforms based on a mobile app.
MVPs that are built clean, so they don’t need to be rewritten later
I have shipped mobile apps involving live data, device communication, and scalable backend systems where reliability matters.
MVP Development
If you need to validate an idea quickly, I can build lean, production-ready MVPs in weeks, not months.
The architecture is designed from day one so the mobile app can scale without being rebuilt.
How I Work
Clear project scoping with realistic timelines
Weekly progress updates with working demos
Thorough testing before delivery
App Store and Google Play submission support
Ongoing support and post-launch updates
Industries
SaaS, FinTech, IoT, On-demand, Inventory, Real estate, Healthcare, Business productivity

Hey, I'm Ankit. I have been a full-stack engineer for 8+ years. I worked for some large scale corporates including DHL: a leading logistics company, Everise: customer experience outsourcing company based in the United States, Neptune Mutual: a decentralized insurance protocol company based in the United Kingdom, Station DEX: a top tier decentralized exchange on X Layer blockchain and others.
I specialize in creating beautiful, pixel-perfect, efficient and performant web and mobile applications (especially SaaS applications) using MERN Stack and Flutter. I once had worked for a startup, dynoCRM: a CRM SaaS, launched their MVP single-handedly in 3 months (which now makes around 1 million dollars per year in subscription fees alone).
When you hire me, here's what we'd do:
1. First, you'd invite me to your job posting.
2. Once everything is accepted, we'd get on a call.
3. Discuss through what the idea is about, and finalize on various things like deadlines, functionalities, and other details.
4. I get back to you in a day, with a detailed plan, including timeline and milestones and how to execute it successfully.
5. Immediately get started once we have an agreement on the plan.
If this sounds good to you, press the "invite button" and we can get started.
