Replit-Built Marketing ROI Calculator for Marketing Teams

Description: Built SwiftROI as a professional, browser-based ROI calculator that helps marketing teams quickly model campaign scenarios, understand real-time financial returns, and make data-driven budget decisions. The app lets users plug in spend, revenue, and channel metrics, then instantly see ROI, break-even points, and performance comparisons across campaigns in a clean, UI-driven workflow.

Designed a dynamic calculation engine that updates ROI, CPA, and LTV-based metrics in real time as users adjust inputs.

Implemented campaign presets so teams can save, duplicate, and compare multiple campaigns or channels side by side.

Built a responsive, accessible UI with modern form components, iconography, and keyboard-friendly interactions.

Enabled PWA support so SwiftROI can be “installed” and used like a native desktop or mobile app.

Integrated observability with browser RUM and tracing to monitor performance and user behavior.

Deployed the app from a Replit-based development environment to production with CDN caching and HTTP/3 for fast global loads.
