SIT Feature
Placeholder
Service Status Page
- • Built to explore how large-scale logistics and delivery platforms maintain reliability across hundreds of microservices, where even seconds of downtime can disrupt millions of orders and real-time dispatch systems.
- • A lightweight Service Reliability Dashboard using FastAPI, async schedulers, HTTPX, and SQLite to automatically track uptime, latency, and version drift across services.
- • Includes a GenAI module powered by Ollama with Hugging Face models like Llama 3.2 to generate fast, on-device incident summaries from recent service data.

AI Logistics Dispatcher
- • Inspired by the Vehicle Routing Problem (VRP) that powers real-time dispatch at the world's largest delivery and ride-hailing platforms, where millions of orders must be intelligently matched to drivers under tight time, capacity, and geographic constraints.
- • An AI-powered catering order allocation system that intelligently assigns delivery orders to drivers based on constraints, priorities, and logistics.
- • Supports multiple LLM providers including Anthropic Claude and OpenAI GPT for flexible, intelligent dispatching.

Messaging Service
- • Built to understand the backbone of real-time communication in large-scale platforms, where in-app messaging between riders, drivers, merchants, and support must be instant, reliable, and scalable to millions of concurrent users.
- • A RESTful messaging service built with TypeScript and Docker, supporting real-time chat between users with message delivery status tracking (delivered, read, failed).
- • Features include chat management, message history, user chat lists, chat metadata, and configurable rate limiting.

Personal Portfolio Website
- • Developed a personal website in 2 weeks in September 2024 using Next.js, React, and TypeScript, styled with Tailwind CSS and Shadcn/ui, and deployed on Vercel to showcase projects and achievements.
- • Continuously improving the website by applying lessons learned from work projects and personal exploration, from backend performance tuning to frontend design refinements.
- • I'm planning to eventually (when I have the time) to integrate a blog section to publish technical write-ups, thought processes, and lessons learned, and sharing insights along the way.
