Abstract

I'm a computer science undergraduate based in Sri Lanka, building full-stack web applications with Laravel and Next.js, and experimenting with applied machine learning in Python. I like projects where real-world data meets clean product UX: dashboards, automation tools, and AI-assisted workflows. Recently, I built an AI weather companion that recommends location-aware activities using real-time weather APIs and Gemini, and a spoiler-blocking browser extension that classifies social content and blurs spoilers with user feedback loops. I'm actively seeking projects where I can contribute as a developer while sharpening system design and software architecture skills.

1. Introduction & Highlights

The primary focus of this site is to demonstrate the practical application of full-stack engineering principles combined with modern AI capabilities. Key contributions include:

  • Integration of LLMs in Consumer Apps: Utilizing the Gemini API to provide context-aware data processing in real-time environments.
  • Privacy-Centric Design: Implementing local-first filtering where possible before offloading to cloud inference.
  • Scalable Architecture: Leveraging Laravel's ecosystem and Next.js for high-performance frontend delivery.

2. Selected Works

2.1 WeatherCraft AI Companion (2024–2025)

Problem: Tourists need alternative activity plans when weather changes unexpectedly, but static weather apps lack context-aware recommendations.

Methods: Implemented a real-time weather tracking system coupled with Gemini Pro to generate dynamic activity suggestions based on current meteorological conditions and user location.

Stack:Laravel (Blade/Breeze) · Tailwind · MySQL · OpenWeatherMap · Gemini API

2.2 NPZ Spoiler Blocker (2024)

Problem: Social media feeds often contain spoilers for trending media, ruining the experience for users who haven't caught up.

Methods: Developed a browser extension utilizing a keyword filter followed by LLM-based semantic classification to identify and blur potential spoilers. Includes a user feedback loop inspired by RLHF principles to improve accuracy.

Results: Achieved high precision in spoiler detection with low latency impact on page load.
