High-Performance Cloud Accelerator & VPN Protocol
Direct hands-on technical oversight by Abdur Rahman from architecture design to complete system deployment.
“Arqify exists to help established businesses replace outdated digital experiences and fragmented systems with a clear identity, exceptional presence and infrastructure built for the long term.”
Client & Project Context
Privacy Tech & Cloud Network Client (Identity protected under NDA). Engineered for high-speed cross-border network acceleration, zero-leak packet encryption, and Microsoft Store client distribution.
The Challenge
Commercial VPN tools often suffered from high latency, packet loss on international routes, DNS leaks, and rigid all-or-nothing routing. Users lacked the ability to selectively proxy web browser traffic versus system-level desktop application traffic.
- •High latency and packet loss on international cross-border network connections
- •Inability of legacy VPN tools to selectively route web browser traffic vs. system-level desktop applications
- •Potential DNS and IP leaks in standard system proxies under heavy multi-threaded network loads
- •Need for a lightweight Windows desktop client meeting strict Microsoft Store publishing guidelines
- •Absence of an integrated referral growth and daily reward mechanism for user retention
The Solution
Designed and engineered a native cloud accelerator application powered by a custom tunneling protocol, dedicated high-throughput server nodes, and a 4-tier network routing engine.
- •Quad-Mode Routing Architecture: Engineered 4 distinct routing modes — WEB Smart (intelligent browser proxy), WEB Global (full browser proxy), TUN Smart (system TUN virtual adapter smart routing), and TUN Global (full system packet tunneling)
- •AutoNode Intelligent Switching: Implemented dynamic ping measuring and auto-routing selecting optimal low-latency server nodes
- •ChaCha20-Poly1305 Encrypted Tunnels: Built zero-log, zero-leak packet encryption across custom regional and international server nodes
- •Microsoft Store Desktop Client: Developed native, lightweight desktop app published on Microsoft Store with PEGI 3 certification
- •Integrated Growth & Affiliate Engine: Built automated QR code referral tracking (20% commission engine), daily check-in rewards, and rebate logs
My Role
As Lead Protocol & Security Architect, led low-level TUN driver interface engineering, routing state machine design, and client application development.
- •Architected custom VPN tunnel protocol and 4-tier network routing state machine
- •Implemented native Windows desktop UI with real-time connection status monitoring
- •Optimized network packet throughput and sub-30ms routing latency for regional endpoints
- •Managed Microsoft Store submission, security compliance auditing, and cloud server deployment
The Result
Delivered a bulletproof, ultra-fast cloud accelerator suite published on Microsoft Store with thousands of active desktop users.
- •Zero DNS/IP leak verification under heavy multi-threaded stress testing
- •Sub-30ms routing latency for regional target endpoints
- •4-tier routing flexibility providing seamless switching between browser-only and full-system TUN acceleration
- •Successfully published on Microsoft Store with high user retention powered by built-in affiliate and daily check-in reward mechanisms
Client Value
Provided enterprise users and privacy-conscious clients with an uncompromised, high-speed secure cloud accelerator engineered from the ground up for maximum routing flexibility.
