Lafine Systems Design delivers high-reliability software engineering, specializing in low-level Linux systems programming, network security, high-volume analytics, and native macOS (Apple Silicon) clients.
From kernel-level systems programming to distributed cloud backends and native Mac desktop applications.
Building ultra-low-latency systems using Linux (nftables / iptables / systemd) and macOS (pf / SMAppService / launchd), network namespaces, raw sockets, and POSIX IPC.
Passive port vulnerability auditing (0.0.0.0 bind detection), real-time ARP spoofing mitigation, intrusion detection log pipelines, ClamAV antivirus integration, and container bypass prevention.
High-speed time-series ingestion pipelines, statistical analysis, and ML inference engines on Linux backends. Real-time multi-threaded processing with Redis and PostgreSQL.
Secure container architecture (Docker / Podman), Linux kernel (sysctl) network stack tuning, and strict resource isolation using cgroups and namespaces.
Native macOS menu bar tools communicating with Linux backends, crafted with SwiftUI and Swift Concurrency adhering strictly to Apple Human Interface Guidelines.
High-performance gRPC, REST, and WebSocket microservices in Go, Rust, Python, and Node.js with secure end-to-end encrypted communication protocols.
Three foundational pillars that guide every system architecture decision.
Strict least privilege enforcement, decoupled packet filtering layers, and eliminating unauthenticated access vectors.
Maximized CPU and memory efficiency through native asynchronous I/O, kernel primitives, and event-driven design.
Uniting Linux server stability with macOS client intuition for robust 24/7 continuous operation.
RoamSwitchKit (the SDK) is free and open source, and ready to use right away for integrating with an already-installed copy of RoamSwitch. If you'd like to bundle and redistribute RoamSwitch itself with your product, we offer plans scaled to your volume — per-seat OEM pricing, annual site licenses, or metered pricing based on active devices.
| Item | Example Terms |
|---|---|
| Billing unit | A dedicated license pool is issued to the partner, billed monthly based on the number of activated devices tied to it. |
| Reference rate | Roughly 20–25% of the $19.99 retail price — about $0.3–0.5 per device/month, or $4–5 per device on a one-time basis. |
| Minimum guarantee | From $500/month. |
* These are general example terms. Final terms are negotiated individually based on scale and requirements.
Whether you need Linux security tools, custom macOS integration, or cloud architecture design, feel free to reach out from the initial concept stage.
