Wallet, loyalty & gift-card development
Money apps are trust apps. I built the admin and operations behind AmarWallet, a loyalty and gift-card platform in Bangladesh — balances you can audit, campaigns vendors actually use, and reconciliation that adds up.

BangladeshCommon questions
How do you keep balances trustworthy?
An append-only ledger as the source of truth, with reconciliation and clear audit trails — never mutating a balance field in place.
