I built a modern AI Chat Assistant web app with a clean, responsive UI and real-time streaming responses. The project focuses on delivering a smooth chat experience (sidebar chat history, message rendering, and fast interactions) while keeping the codebase production-ready with strong TypeScript typing, linting, and scalable structure. On the backend side, I implemented a Next.js API route that streams model output and supports “tool-like” capabilities (e.g., weather/search/calculation style workflows). On the frontend, I designed reusable UI components and handled common React/Next pitfalls like hydration issues and render loops to ensure stable production builds.

Project: Resilient Web Automation & Monitoring System (Python) Built a production-style automation framework in Python to query and monitor product endpoints at scale with strong reliability features. The system supports proxy/profile rotation, configurable request headers/session settings, and automatic detection of protection challenges (e.g., 403 responses and challenge URLs) to safely stop, rotate, and continue processing without breaking the run. It includes structured logging and response validation (e.g., distinguishing genuine 404 “not found” from access blocks), plus clear error handling and retry controls for long-running jobs. The result is a maintainable automation codebase designed for high-volume checks, operational visibility, and predictable behavior in real-world network conditions. Tech used: Python, requests/urllib3, TLS-capable HTTP client patterns, proxies, structured logging, configuration-driven workflows.

The project focuses on delivering a smooth chat experience (sidebar chat history, message rendering, and fast interactions) while keeping the codebase production-ready with strong TypeScript typing, linting, and scalable structure. On the backend side, I implemented a Next.js API route that streams model output and supports “tool-like” capabilities (e.g., weather/search/calculation style workflows). On the frontend, I designed reusable UI components and handled common React/Next pitfalls like hydration issues and render loops to ensure stable production builds.

Project: Resilient Web Automation & Monitoring System (Python) Built a production-style automation framework in Python to query and monitor product endpoints at scale with strong reliability features. The system supports proxy/profile rotation, configurable request headers/session settings, and automatic detection of protection challenges (e.g., 403 responses and challenge URLs) to safely stop, rotate, and continue processing without breaking the run. It includes structured logging and response validation (e.g., distinguishing genuine 404 “not found” from access blocks), plus clear error handling and retry controls for long-running jobs. The result is a maintainable automation codebase designed for high-volume checks, operational visibility, and predictable behavior in real-world network conditions. Tech used: Python, requests/urllib3, TLS-capable HTTP client patterns, proxies, structured logging, configuration-driven workflows.
