01 Context → 02 Challenge → 03 Architecture → 04 Implementation → 05 Outcomes

01. Context & Objectives

Consumer brands run targeted sampling programs to introduce new formulations to interested cohorts and collect structured qualitative feedback.
Architectural Mandate

Ensure fair sample distribution per household, manage regional sample inventory quotas, and capture structured post-sampling survey feedback.

02. The Architectural Challenge

Scaling Constraints & Critical Bottlenecks

Preventing duplicate sample claims across consumer accounts and managing surge traffic during social campaign announcements.

High-volume campaign launches create instantaneous concurrency spikes that risk depleting promotional quotas past available stock.

03. Engineering Approach & System Design

Decoupled Architecture & Execution Strategy

Implemented address deduplication heuristics, Redis-based rate limiting on campaign claims, and asynchronous survey ingestion pipelines.

04. Implementation & Key Deliverables

What Urjasoft Built & Deployed

Engineered a promotional sampling platform featuring campaign quota enforcement, claim deduplication, and structured consumer review collection.

Atomic Redis increment operations enforce strict per-campaign quotas without database race conditions during traffic surges.
Implementation Details

Created dynamic sampling campaign landing pages, automated quota exhaustion indicators, and aggregate rating collection components.
