URL Shortner
A full-stack URL shortening service that converts long URLs into short, shareable links. Features cryptographically secure short code generation, duplicate detection to reuse existing short URLs, fast redirects, and a responsive UI. Built with a scalable architecture supporting high traffic with collision handling, health monitoring, and structured logging.
Real-Time PubSub System
A production-ready WebSocket-based publish-subscribe system built with Go, demonstrating essential concurrency primitives including goroutines, channels, context management, and graceful shutdown patterns. Features a simplified architecture that balances production readiness with code clarity.
The Career Vault
Built an AI assistant that uses LangChain and ChromaDB to automate job applications. Implemented a RAG pipeline to dynamically tailor resumes and cover letters by matching candidate experience to job descriptions using local LLMs (Ollama/DeepSeek).
