Hello, I am Himanshu, a full stack app developer with 7.5+ years of experience. I build complete products from start to finish: the mobile app, the backend API, and the admin panel. That means you hire one developer instead of three. I am Top Rated with a 100% Job Success Score, and I've built, launched, and sold apps on the App Store.
What I build:
• Mobile apps: native iOS with Swift and SwiftUI, plus Flutter and React Native for iOS and Android
• Backend and APIs: Node.js REST APIs, authentication, external integrations, and serverless functions
• Web and admin panels: Next.js frontends and admin dashboards to run your product
• AI features: Claude and OpenAI API integration, OCR, and workflow automation
• Full launch: App Store and Play Store submission, RevenueCat subscriptions, and analytics
Apps I've shipped, all live on the App Store:
• Reko, a subscription tracking app with renewal reminders, spending analytics, and support for multiple currencies. I built it solo, and it was acquired.
• Recipe Keeper & Meal Planner, a recipe organizer and meal planning app with recipe import, weekly meal calendars, automatic grocery lists, and ingredient scaling.
• Archcorp ERP, an enterprise resource planning solution with operational workflows, reporting, user management, and business process automation.
• Timechart AI, a workforce management platform with attendance tracking, analytics, reporting, and business insights.
From a polished consumer app to a full enterprise ERP, I build and ship complete products, and I treat yours like my own because I ship my own. I work fast and communicate in plain English.
