A full-stack voting and decision-making application engineered with strong emphasis on system architecture, data integrity, and real-time visualization. Designed to handle concurrent submissions atomically and present live interactive analytics.
The Problem
Traditional polling methods often suffer from ballot duplication, lack of real-time result updates, and convoluted creation workflows for administrators.

System Architecture
Layered MVC & Event-Driven Voting Pipeline
The system decouples the client interface from the backend API gateway, ensuring all incoming votes pass through verification guards before committing to the relational store.
Technology Stack
Technical Challenges
Preventing race conditions during concurrent voting spikes was solved using strict SQL transactions with row-level locking mechanisms.
Engineered Outcome
Delivered an intuitive, zero-duplicate polling experience capable of processing concurrent votes smoothly with instant visual feedback.
