Project Overview
Engineered native iOS & Android clients with a distributed WireGuard network for instant one-tap encrypted privacy, zero DNS leaks, and minimal latency.
The Operational & Engineering Challenge
Mobile VPN clients often suffer from high battery drain, sluggish connection handshakes, connection drops across cellular/Wi-Fi transitions, and confusing configuration settings. The objective was to build a clean, consumer-grade mobile application that provides instantaneous one-tap connection with rigorous zero-logs privacy guarantees.
- Strict zero-logs architecture with memory-only server tunnels.
- Seamless auto-reconnect across dynamic IP and mobile cellular-to-Wi-Fi network switches.
- Sub-second handshake speed without battery penalties.
- Compliance with strict Apple App Store and Google Play network extension guidelines.
Engineering & Architecture Approach
We designed and engineered native mobile applications utilizing modern WireGuard and OpenVPN protocols via custom platform tunnels (NetworkExtension framework on iOS, VpnService on Android). Backed by an automated telemetry and server health mesh, the client dynamically routes traffic to the lowest-latency server location while maintaining encrypted kill-switch protection.
Custom WireGuard C-bindings wrapped in Swift (iOS) and Kotlin (Android).
Device-level packet filtering preventing unencrypted leakage if tunnel drops.
Granular per-app routing allowing local traffic bypass without breaking encrypted tunnels.
Real-time latency probe system selecting optimal global PoPs in under 150ms.
Key Engineering Decisions
Chose WireGuard over legacy IPsec for 3x faster handshake times and drastically reduced battery consumption.
Implemented offline-cached configuration profiles so users can reconnect even in low-connectivity zones.
Built deterministic telemetry to detect degraded server nodes without logging user IP or traffic data.
Verified Outcomes
Sub-second 1-tap connection handshake time.
Zero DNS or IPv6 leakage across third-party packet audits.
Flawless automated reconnection during 5G/Wi-Fi transitions.
Full App Store and Google Play approval with zero policy violations.
