MUHAMMET ÇİMEN // BACKEND & SYSTEMS ENGINEER

High-performance backend & serverless systems.

Building scalable backend architectures, privacy-focused software, custom network tunneling protocols, and low-level Android daemons with Go, Rust, Python, and Cloudflare.

RUST // LOW-LEVEL SYSTEMS & TUNNELING ● AURA ACTIVE

Zero-cost abstractions, memory safety without GC, custom high-speed WireGuard socket tunneling, and Tokio async runtime concurrency.

< 1.0ms P99 Socket Latency
100k+ Concurrent Streams
10+ Protocols & Tunnels
01 // CLOUD & SERVERLESS EDGE INFRASTRUCTURE

Distributed Cloudflare Edge & GCP infrastructure.

Architecting zero-cold-start distributed compute on Cloudflare Workers, KV, Durable Objects & Zero Trust Tunnels combined with scalable Google Cloud Platform (GCP Compute Engine, VPC Peering & Network Routing) backbones.

Cloudflare Ecosystem: Edge workers, KV data stores, smart routing, DDoS mitigation, and Cloudflare Tunnel zero-trust gateways.
Google Cloud Platform (GCP): High-availability VPCs, custom firewall rules, load balancers, and bare-metal compute nodes.
02 // NETWORKING, VPN & ENCRYPTED PROTOCOLS

High-throughput VPNs, proxies & stealth tunneling.

Deep expertise in low-level socket programming, anti-censorship protocols, virtual network interfaces, and encrypted DNS architectures.

TUNNELING & VPN:
WireGuard OpenVPN v2ray (VLESS/VMess) Hysteria (QUIC) Shadowsocks
PROXIES & ENCRYPTED DNS:
SOCKS5 / HTTP Proxy DoH (HTTPS) DoT (TLS) DoQ (QUIC) DNS / Geo-DNS
