Featured Projects

Neural Network Visualizer

What is this?

Understanding backpropagation is intuitive for humans but difficult to visualize in real-time. The goal was to create a tool that renders network weights dynamically without freezing the browser thread.

How to do it?

I utilized WebGL for rendering the node connections, allowing for 10,000+ interactive elements at 60fps. The state management logic was offloaded to a Web Worker to ensure UI responsiveness. I also implemented a custom shader pipeline to handle the glowing connections efficiently.

EcoTrack Analytics

What is this?

Aggregating sensor data from disparate sources into a unified dashboard for municipal energy tracking. Data consistency and real-time alerts were critical requirements from the city council.

How to do it?

Designed a microservices architecture using Go. Implemented a time-series database (TimescaleDB) for efficient data storage and retrieval. Created a custom React dashboard with D3.js visualizations that update via WebSockets for real-time monitoring.

Geometric Portfolio

What is this?

To create a personal brand that reflects both architectural precision and organic growth. The challenge was to implement complex overlapping geometries without sacrificing semantic HTML or accessibility.

How to do it?

Leveraged Astro for its zero-JS default to ensure maximum performance. Used modern CSS features like Grid, clamp(), and custom properties to build a responsive design system. The geometric shapes are pure CSS, reducing the need for heavy image assets.
