Blockchain infrastructure
NexQloud
VAPT-certified mobile application
Secure mobile control for servers, wallets, NFT licenses, device status, token balances, and care-plan subscriptions.
The assignment
Flutter engineer responsible for mobile flows, secure storage, native hardening modules, and sensitive account workflows.
The hard part
Expose blockchain-backed infrastructure clearly on mobile without weakening the handling of accounts, credentials, or transactions.
Architecture decisions
- Moved sensitive values into protected device storage with explicit lifecycle handling.
- Added native hardening modules to raise the cost of reverse engineering.
- Aligned data flows with VAPT review requirements instead of treating security as a final pass.
What changed
- Delivered security controls that passed VAPT review.
- Unified device, wallet, NFT, and subscription management in one mobile surface.
- Reduced ambiguity around high-consequence account actions.
Need this kind of ownership?
I work best where mobile product quality, release confidence, and maintainable architecture all matter.
