Freelance Loyalty & Rewards Engine Programmer: Transactional Points Ledgers & Gift Card Systems in Go

Enterprise retail loyalty programs, airline/hospitality point exchanges, and closed-loop digital gift cards require the exact same double-entry accounting rigor and row-level locking as core banking ledgers. Without strict ACID isolation and idempotency keys, concurrent redemption requests allow users to double-spend balances.

As a Senior Freelance Golang & FinTech Programmer, I have architected high-concurrency loyalty point exchanges and digital wallet ledgers. Hire Aldian Fazrihady on Upwork (aldianf).
