TechCorp SaaS Dashboard

This is an excellent summary of a high-stakes, large-scale project that directly ties technical work to a massive business metric (customer retention). This is exactly what employers want to see.

Here is the extended, portfolio-ready version, emphasizing your leadership role in the front-end rebuild and the engineering decisions that led to the 25% retention boost:

Project: TechCorp Flagship Dashboard Rebuild

Leading the complete front-end overhaul of a critical enterprise analytics dashboard using React, TypeScript, and D3.js. The goal was to transform a slow, static "report" into a high-performance, real-time interactive "tool" to combat significant customer churn.

🚀 The Challenge

TechCorp's flagship analytics product was facing a critical liability: its core dashboard. It suffered from being slow, required constant page refreshes to load new data, and presented users with overwhelming, static tables of numbers. This severe lack of usability and real-time insight was directly responsible for a high rate of customer churn. The mandate was clear: rebuild the dashboard from the ground up to deliver speed, intuition, and real-time value.

🛠️ The Solution & Technical Leadership

I led the full front-end rebuild, focusing on architecture that prioritized scalability, reliability, and real-time data visualization.

• Architectural Foundation: Component-Driven React UI We initiated a component-driven architecture using React. Every UI element, from navigation bars to complex data tables, was broken down into its own reusable, stateful component. This modular approach significantly improved development speed, maintenance, and consistency across the massive application.

• Guaranteed Reliability: TypeScript for Data Integrity The biggest technical risk was managing the massive and complex data models streaming from the backend. I implemented TypeScript across the entire front-end codebase.

  • Impact: TypeScript was critical for enforcing type-safety across all data inputs and outputs, effectively eliminating entire classes of bugs that had plagued the old system and ensuring reliable data flow between components and visualizations.

• The Killer Feature: Real-Time Visualization with D3.js To transition from a static report to a "living tool," I utilized D3.js to develop a bespoke library of custom, interactive charts.

  • This allowed for real-time data binding: charts could update instantly via WebSockets or polling without requiring a full page refresh. Users could now "play" with their data—filtering, zooming, and drilling down—with zero latency, unlocking actionable insights.

• Assurance & Quality: Unit Testing with Vitest In an analytics product, data accuracy is non-negotiable. We implemented Vitest to write comprehensive unit tests specifically for all data transformation and filtering functions. This engineering step guaranteed that the numbers presented on the screen were always 100% accurate, establishing user trust.

📈 The Outcome & Impact

The new dashboard was a transformation—fast, intuitive, and, most importantly, highly useful. By turning data into an interactive experience, we directly solved the core problem of customer dissatisfaction.

• Business Impact: Increased user retention by a massive 25%. This direct result validated the technical investment and stopped the customer churn that was threatening the product's viability.

• Product Transformation: The dashboard transitioned from a liability to a key competitive advantage, making the analytics tool truly valuable to its users.
