Petr Chlíbek 

Backend developer focused on building reliable, scalable server-side systems.

I design APIs, distributed services, and infrastructure that handle real-world traffic while staying maintainable.

I value clean, purposeful code and dig into issues to understand the root cause rather than just patching problems.

A lightweight TCP proxy server written in Go that filters incoming connections based on IP reputation using IP2Proxy.

It acts as a middleware between clients and your backend service, automatically terminating connections from known proxies, VPNs, and high-risk IP addresses before they reach your application.

• TCP Proxy: Transparently forwards traffic to a backend service.
• Bot Filtering: Blocks connections from known proxies and suspicious IPs.
• IP2Proxy Integration: Uses the IP2Proxy database for accurate IP reputation data.
• Docker Ready: Includes a multi-stage Dockerfile for easy deployment.

A minimal HTTP server implementation in Node.js designed for simplicity and educational purposes.
