Software Developer 1

A nationwide loyalty rewards program was experiencing recurring downtime. The proximate cause was load; the underlying cause was an abuse pattern that had not been identified.

Worked back through transaction logs until the duplicate-transaction pattern was clear. Built an automated identification and remediation tool to detect and act on the pattern at write time.

Outages stopped. The business recovered significant revenue that had been leaking through the abuse. The investigation led to a promotion to Software Developer II four months into the role.

The loyalty rewards program had no internal surface for administrators to manage the program, review submissions, or monitor activity.

Implemented the admin website against provided designs, covering management pages, an approver-facing receipt OCR review interface, and dashboards.

The business gained a centralized surface to manage the loyalty rewards program. Approvers could review OCR-processed receipts directly within the system.

Multiple teams were maintaining separate voucher logic for promotions. The implementations were nearly identical and inconsistently buggy.

Built a generic voucher engine with the abstractions teams required: eligibility, expiration, redemption, and fraud signals.

Adopted across the program. Teams that had been maintaining separate voucher implementations migrated to the shared engine.
