About this gig

Stop gambling with your vision. Hire a Senior Architect with 8+ years of proven delivery.


Most developers build basic layouts, but few handle "heavy lifting" like complex APIs, secure wallets, and SDK integrations. With 200+ apps deployed, I build scalable, secure ecosystems for iOS & Android.


My Specialized Tech Stack:

  • Fintech: Stripe, Revolut, Digital Wallets, & Secure Checkout.
  • Identity/Security: IDverse (KYC), Biometric Auth, & Data Encryption.
  • Real-time: PubNub, Firebase, Chat/Call, & Lottie Animations.
  • Infrastructure: Deep Linking (Branch.io), Google Maps API, & RESTful Architecture.
  • Advanced: Custom SDKs, Media Galleries, & QR/Barcode Scanning.


Solutions I Excel In:

  • On-Demand & Marketplaces: Real-time tracking & multi-user roles.
  • Fintech & E-wallets: Secure, transaction-heavy applications.
  • Enterprise Tools: Complex ERP/CRM mobile extensions.
  • Social & Auth: Scalable chat, video calling, & custom logic.

Why Me?

  1. Clean Code: Modular, documented, and maintainable.
  2. Store Ready: 100% App Store/Play Store approval rate.
  3. Security: Bulletproof data & payment handling.
